If you are using a Windows PC, probably you’d have seen this message, especially while trying to install applications from some not-so-popular vendors on your computer.

How to unblock a file from windows’ “publisher could not be verified” warning

There isn’t anything to worry about this message- it’s just a warning that you can simply ignore. Here, I can summarize the cause of this problem in one sentence, “Windows fails to recognize publisher of that program.”

How this explanation seems to you? If you’ve doubts, try to install programs from any recognized software vendors. For example, let’s try to install Remo Recover 4.0 on the same PC. Perhaps, you’d see a pop-up like this.

How to unblock a file from windows’ “publisher could not be verified” warning

Here you can see Windows has identified the program as a verified publisher – which did not happen with the first program. This happens because of Microsoft’s policy that asks vendors to get the approval as verified publisher. For this, the vendor needs to earn a code signing certificate for their product from a trusted third party provider like DigiCert. Consumers often trust programs powered by these certificates like shrink-wrapped programs they purchase from a retail store. Actually, a code signing certificate is nothing more than a document for validating a program in order to prove it has not been altered by a third party.

But, what’s the guarantee that such programs do not harm your computer? The reality is, any software vendor can acquire a code signing certificate for their program for a sum of money. So, how can you assure that such programs do not have malicious nature?

Also, you can’t blindly consider that an unverified program will disrupt your system. So it doesn’t matter if a program is verified or unverified, sometimes these programs can put your PC at risk.

Precaution you should take before Running an Unverified Program

It is always best to run a verified program, but if you still want to run a program from unknown source ignoring the security warning, it is recommended to at least create a system restore point. So that you can always restore the system to a previous working state if something goes wrong.

Users need to unblock downloaded files from the Internet to stop Windows 11 from blocking access to them. When you click such a file in Explorer, it shows a security warning. Also, for some files like executables (*.exe), Windows blocks them from opening. Here’s how to unblock such a file and stop Windows 11 from blocking them.

By default, Windows adds a zone information to each of the files downloaded from the Internet or received by email. When you are opening any file, the operating systems analyzes that data. If the zone info presents and is refers to the “unsafe” source, you see a warning.

This functionality is implemented in the Attachment Manager component. It writes the zone information to a special area called “alternate data steam” which is invisible to the end user. Such streams, also known as “metadata”, only exist on NTFS partitions.

Attachment Manager identifies how risky the downloaded file can be for you by several factors. In short, it checks with what program you open the file, the type of the file, and the source from where you obtained the file.

There are three levels of security warnings you may see when opening a downloaded file.

  • High – You see the message like “Windows found that this file is potentially harmful. To help protect your computer, Windows has blocked access to this file.” This warning typically appears for download executable files that don’t have a digital signature and aren’t known for SmartScreen.
  • Moderate – This applies to certain documents and executables received from LAN. For the latter, you may see the “The publisher could not be verified. Are you sure you want to run this software?” message.
  • Low – For files that are “safe” regardless of the source, Windows doesn’t notify the user and allows opening them.

If you find inconvenient to see such prompts every time you open the downloaded files, you need to unblock them. Here is how.

When downloading files from the Internet, Windows will look at the file and categorize it as High Risk, Moderate Risk, or Low Risk and decide if it’s safe for you to run the file. Windows will then allow or block the file. If you know a file is safe, but blocked from running by Windows Security, here are some options to unblock a blocked file.

Fix Downloaded Files from being Blocked in Windows 10: When you try to open or execute the files you just download over the internet you may receive a security warning stating “The publisher could not be verified and the file might be a security threat“. This happens when Windows can’t verify the digital signature of the file, hence the error message. Windows 10 comes with an Attachment Manager which identifies an attachment either safe or unsafe, if the file is unsafe then it warns you before you open the files.

How to unblock a file from windows’ “publisher could not be verified” warning

Windows Attachment Manager uses the IAttachmentExecute application programming interface (API) to find the file type and file association. When you download some files from the Internet and save it on your disk (NTFS) then Windows add specific metadata to these downloaded files. These metadata are saved as an Alternate Data Stream (ADS). When Windows adds metadata to the download files as an attachment then it is known as Zone Information. This zone information is not visible and is added to the download file as an Alternate Data Stream (ADS).

When you try to open the downloaded file then Windows File Explorer also checks the zone information and see if the file came from an unknown source. Once Windows recognizes that the file is an unrecognized or came from unknown sources the Windows Smart Screen warning will appear stating “Windows smart screen prevented an unrecognized app from starting. Running this app might put your PC at risk“.

If you wish to unblock the file then you could do that manually by right-clicking on the downloaded file and then select Properties. Under properties window checkmark “Unblock” then click Apply followed by OK. But users don’t prefer this method as it’s very annoying to do that every time you download a file instead you could disable the additional zone information which means there won’t be any smart screen security warning. So without wasting any time let’s see How to Fix Downloaded Files from being Blocked in Windows 10 with the help of the below-listed tutorial.

25 thoughts on “How to unblock files downloaded from Internet in Windows 10”

it’s very annoying message! thanks!

Don’t mention it.

Thank you for this! My problem is a little more complex. I have sub-folders and sub-sub-folders with files to get unblocked. Is there a way to unblock all files on a drive, or at least all files within folders & sub-folders. I have also been unsuccessful at getting downloads to not be blocked in the first place.

Open Powershell and run the command below.
This will work for you silently:
dir c:\users\winaero\downloads -Recurse | Unblock-File
This one will report which files will be unblocked, but WILL NOT UNBLOCK them (the report only):
dir c:\users\winaero\downloads -Recurse | Unblock-File -WhatIf
Enjoy.
It is a good idea to cover it tomorrow.

I was really kicking myself for having forgotten to ‘Unblock’ a ZIP file containing a TON of files I had to take off Copy.com (because they’re shutting down) and this really saved me from having to sit and do this by hand, which would have taken, well, quite some time.

To prevent sites from having this error in the future, you need to add them to trusted sites. This is useful when you download often from a particular site.

This can be done (in IE8 onwards) by setting the following registry keys:

Create new Key under:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains\exampledomain.com]

Create a DWord Value for each protocol you need to trust; for example
“http”=dword:00000002
“https”=dword:00000002

Quality – how annoying is that and painful to do one by one – simple things and all that.

Thanks for this, although is there a way to make it do entire folders and subfolders?

Sure. Use
Get-ChildItem -recurse

Is this the correct way it write out the command to unblock all files in folders and subfolders? ‘Get-ChildItem -recurse | unblock-file’ ? Thanks.

I use the following command

Another way to bulk unblock files is to ZIP them, delete the originals, then UNZIP them.

-Recurse was the switch I was missing to take care of subfolders .
Thanks!

  1. After Command Prompt opens, copy and paste the name of the file you want to run. Make sure you include the “.exe” extension at the end of the file.

Solution 2: Edit the Properties of the File

Sometimes Windows blocks download executable files if its unable to verify its origin. However, if you are certain that the file you are trying to run is safe to use, you can overrun their security settings by editing the file’s properties.

  1. Right click on the file and select Properties at the bottom of the context menu.
  2. After you navigate to the General tab you should be able to see the “This file came from another computer and might be blocked to help protect this computer” message.
  3. Select “Unblock” and click Apply in order to apply these changes. Try running the file again.

Solution 3: Using the Internet Explorer

Since some of the most essential Windows 10 settings can still be controlled if you try using Internet Explorer, this problem can also be addressed if you tweak certain settings in Internet Explorer. Follow the steps below carefully in order to try and fix you issue.

  1. Open Internet Explorer by locating it in the Start menu. It should be located in the default apps list.
  2. On the Tools menu, click Internet Options.

  3. Locate the publisher whose software or file has been blocked and click on Remove in order to get rid of the security warning you have been receiving.
  4. Try running the file again.

Solution 4: Disabling the Security Warning and User Account Control

Since Windows can sometimes overreact with their security warnings and messages, you can turn them off for a short period of time needed for you to install the program you are struggling with. You should undo these changes as soon as you are done with the process since the last thing you want to do is leave your computer unprotected.

*Disable Security File Warning**

  1. Open Internet Explorer by locating it in the Start menu. It should be located in the default apps list.
  2. On the Tools menu, click Internet Options.

How to unblock a file from windows’ “publisher could not be verified” warning

  1. Locate the “Launching Applications and Unsafe Files” which should somewhere between the middle of the list and the end. Click on the radio button next to Enable.
  2. Certain prompt may appear notifying you that changing these settings may be unsecure for your computer. You can ignore them but make sure you undo these changes later.

Unfortunately, some users have reported that, even after they have performed this method and they were able to get rid of the annoying error message, another message appear stating “This app has been blocked for your protection”. This is controlled by User Account Control and you may have to disable it for now if you want to install the file. Make sure you re-enable it after you install the file.

  1. Open Control Panel by searching for it in the Start menu.
  2. Switch the View by option in Control Panel to Large Icons and locate the User Accounts option.How to unblock a file from windows’ “publisher could not be verified” warning
  3. Open it and click on “Change User Account Control Settings”.
  4. You will notice that there are several different options you can choose on the slider. If your slider is set at the top level, you will definitely receive more of these pop-up messages than usual.How to unblock a file from windows’ “publisher could not be verified” warning
  5. Try decreasing this value by one if it’s at the top slider and check to see if it helped.
  6. We recommend you turn it off for now as the file should probably install successfully. You may also be able to run the file even if you don’t disable UAC completely, but you should definitely leave it on as it serves to protect your PC.

Also home of the Windows Defender Antivirus, Windows Security includes tools which can block malware before it reaches your data, and this is part of a more aggressive approach that makes prevention a priority on every Windows 10 device.

SmartScreen, for example, is part of this stage, and it warns you whenever files that you want to launch could pose a threat to your device.

Basically, SmartScreen was originally implemented in Microsoft’s browsers to alert whenever users tried to load potentially dangerous websites. In Windows 10, Windows Defender SmartScreen can also let you know when the files that you try to launch could harm the computer.

The warning that Windows Defender SmartScreen displays when potentially dangerous applications are detected is the following:

“Windows protected your PC. Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.”

How to unblock a file from windows’ “publisher could not be verified” warning

Microsoft says it analyzes a bunch of data before deciding whether SmartScreen should block the launch of an application or not:

“Windows Defender SmartScreen uses information from Internet Explorer, Microsoft Edge, and Windows users around the world as well as anti-virus results, download volumes, download history, URL reputation, and many other criteria to determine the likely risk of downloaded programs.

For example, programs that are downloaded by many users over a long period of time without a history of malware are not likely to be malicious. This warning indicates that caution should be taken before running the downloaded program, especially if the download is not digitally signed.”

Unblocking a file that was previously blocked by Windows Defender SmartScreen and preventing the warning from showing up once again is easier than you think, albeit it’s definitely not the most straightforward.

First and foremost, you must find the location of the executable file on your PC. If you attempt to launch it from a shortcut, just right-click the file > Open file location.

Once you locate it, right-click the file > Properties > General. In the lower part of the screen, there should be a message reading:

This file came from another computer and might be blocked to help protect this computer.
Simply check the box next to this option that reads Unblock and then hit Apply in the same window. At this point, SmartScreen should be disabled for the selected app and the warning should no longer show up on launch.

How to unblock a file from windows’ “publisher could not be verified” warning

What’s very important to know is that despite Windows Defender becoming a more powerful security product, it can very well send false positives too. So not all files marked as dangerous can harm your device.

Microsoft recommends users to first check if the file is digitally signed by a software publisher. To do this, right-click the file > Properties > Digital Signatures.

Then, you need to check the download source. “How were you directed to this download? Was the download link unsolicited, such as from an email, instant message, or social networking post? If the download link was unsolicited – even if it looks like it’s from someone you trust – it is more likely to be malicious,” the software giant says.

And last but not least, if you download a game that’s supposed to be popular, but SmartScreen issues a warning that only shows up for unknown files, this should sound like a huge warning.

Eventually, if you’re not sure if a downloaded file is dangerous or not, it’s better not to run it, or at least, to launch the process in a secure environment like Windows Sandbox.

Open System by clicking the Start button , right-clicking Computer , and then clicking Properties .

Click Advanced system settings . If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.

Under Performance , click Settings .

Click the Data Execution Prevention tab, and then click Turn on DEP for all programs and services except those I select .

To turn off DEP for an individual program, select the check box next to the program that you want to turn off DEP for, and then click OK .

If the program is not in the list, click Add . Browse to the Program Files folder, find the executable file for the program (it will have an .exe file name extension), and then click Open .

Click OK , click OK in the System Properties dialog box if it appears, and then click OK again. You might need to restart your computer for the changes to take effect.

If you have been frustrated by the warning message on Windows computers “This file came from another computer and might be blocked to help protect this computer.”, you are not alone. The warning might pop up when you try to open a file that you downloaded from the Internet. It can cause a decent amount of frustration because of the way it is implemented.

If you right-click on a single file and choose Properties, you can see the Security section at the bottom of the window.

“This file came from another computer and might be blocked to help protect this computer.”

How to unblock a file from windows’ “publisher could not be verified” warning

You can check the box (in Windows 10) or click the Unblock button (in Windows 7/8) to unblock the file. However, if you have multiple files, you cannot select more than one and view the properties to unblock all of the files at once. Instead, you will have to check each file separately and unblock them one at a time. One tip was to always unblock a zip file before extracting it for this reason.

How to unblock a file from windows’ “publisher could not be verified” warning

You can disable the setting through Group Policy by enabling the setting ‘Do not preserve zone information in file attachments’ found under User Configuration -> Administrative Templates -> Windows Components -> Attachment Manager. I don’t recommend this as I prefer to keep security warnings in place. I previously dealt with this several years ago when a script had problems running a blocked file where the solution was to add a UNC path of the file to the Trusted Sites Intranet zone.

Microsoft has a command line utility called ‘streams’ that you can download and tell it to remove the NTFS-attached data stream that identifies a file as downloaded from the Internet. The command for this is streams -s -d [directory path]. Nirsoft also has a utility called Alternate Data Streams with similar functionality.

Rather than having to download a separate executable, there is native PowerShell functionality that will allow us to unblock multiple files at a time. The command is:

How to unblock a file from windows’ “publisher could not be verified” warning

This command will recurse through a directory and all sub-folders and unblock them. If you have a few files that you trust but were downloaded from the Internet, you can quickly get them all by sticking them in a folder and running that PowerShell command on them to have the stream property removed. It certainly beats the weird issues that can be caused by this setting and weird workarounds to zip the files up, unblock the zip and then extracting the files again.

Sometimes, when you try to install software that Windows 10 cannot verify, you might see this dialog that remind you publisher has been blocked in Windows 10.

Windowsin suojausvaroitus -valintaikkuna avautuu, kun suoritat tai avaat tiedoston, jota Microsoft ei tunnista luotettavana tiedostona. Tiedosto on estetty, ellei nimenomaisesti sanota Windowsille, että tiedostoa voidaan käyttää tai avata.

Jos olet ladannut tiedoston luotettavasta lähteestä ja suoritat sen usein, voit poistaa sen tiedoston, jotta et saa Security Warning -valintaikkunaa aina, kun suoritat sen.

VAROITUS: Varmista, että vain tunnistat tiedostot ovat luotettavista lähteistä. Tuntemattomien tiedostojen poistaminen voi lisätä riskiä, ​​että tietokoneesi voi saada haittaohjelmia tai viruksia.

Tiedoston poistaminen käytöstä suoraan Security Warning -valintaikkunasta

Helpoin tapa vapauttaa tiedosto on suojausvaroituksen valintaikkunan valintaruutu. Kun suojausvaroitus tulee näkyviin, poista valinta "Kysy aina ennen tämän tiedoston avaamista" -ruutuun. Napsauta sitten "Suorita" tai "Avaa" avataksesi tai avaat tiedoston.

HUOMAUTUS: Tämä menetelmä estää tiedoston missä tahansa tietokoneessa.

Jos Käyttäjätilien valvonta -valintaikkuna tulee näkyviin, jatka valitsemalla Kyllä.

HUOMAUTUS: Käyttäjätilien valvonta -valintaikkuna tulee näyttöön, jos tiedosto on sijainnissa, jossa käyttäjätunnuksella ei ole käyttöoikeutta oletuksena. Käyttäjätilien valvonnan valintaikkunan näyttäminen riippuu myös Käyttäjätilien valvonnan asetuksista.

Seuraavan kerran, kun suoritat tai avaat tämän tiedoston, et näe suojausvaroituksen valintaikkunaa.

Kuinka vapauttaa tiedoston sen ominaisuuksien avulla

Voit myös vapauttaa tiedoston muuttamalla asetusta tiedoston ominaisuuksiin.

HUOMAUTUS: Tämän menetelmän avulla voit vapauttaa tiedoston vain, jos tiedosto on jonkin käyttäjän kansion paikoista, kuten työpöydän, latausten tai asiakirjojen (tai sijainnit, joilla käyttäjätunnuksella on käyttöoikeus). Jos se ei ole yhdellä näistä sijainneista, sinun on ensin siirrettävä tiedosto johonkin näistä sijainneista, poista se käytöstä ja siirrä tiedosto takaisin alkuperäiseen sijaintiinsa.

Napsauta hiiren kakkospainikkeella tiedostoa, jonka haluat poistaa ja valitse ponnahdusvalikosta "Ominaisuudet".

How to unblock a file from windows’ “publisher could not be verified” warning

Ominaisuudet-valintaikkuna avautuu. Jos käytössä on Windows 10, valitse Yleiset-välilehdellä Poista lukitus -valintaruutu, jotta laatikossa on valintamerkki. Napsauta Windows 7: ssä ja 8 / 8.1: ssa Yleiset-välilehden "Unblock" -painiketta. Napsauta "OK".

HUOMAUTUS: Jos et näe Poista lukitus -valintaruutu tai -painiketta, tiedosto on jo estetty.

How to unblock a file from windows’ “publisher could not be verified” warning

Kun suoritat tai avaat tämän tiedoston nyt, Security Warning -valintaikkuna ei tule näkyviin.

Tiedostojen lukituksen poistaminen SmartScreen-suodattimen avulla Windows 8 / 8.1 ja 10: ssa

Microsoftin SmartScreen-suodatin estää tuntemattomat ja haittaohjelmat toimimasta, ellet anna lupaa tehdä niin. SmartScreen-suodatin, jota käytetään Internet Explorer 8: n ja 9: n osaan. Windows 8: n mukaan SmartScreen-suodatin on kuitenkin integroitu Windows-käyttöjärjestelmään. Voit avata tiedostot SmartScreen Filter -valintaikkunasta, jos kohtaat sen Windows 8 / 8.1 tai 10: ssa.

Muista olla erittäinvaroen, kun valitset tiedoston eston ja varmista, että tiedät, että tiedosto tulee luotettavasta lähteestä.

my question is : how can I get rid of "The Publisher could not be verified. Are you sure you want to run this software"?

This is due to a setting in Windows that flags .exe files as ‘high-risk’. You can unblock them using the Unblock-File command before running the executable.

How to unblock a file from windows’ “publisher could not be verified” warning

1 – Running external executables is a well-documented use case directly from Microsoft.

2 – You must make sure the exe is not marked as from an untrusted source, meaning, you downloaded this from the internet and it is marked with the internet alternate data stream (ADS). You need to remove this stuff on internet-based downloads, using the cmdlet.

. or open Windows Explorer, right-click, select properties, unblock. See the help files for details and examples.

La finestra di dialogo Avviso di sicurezza in Windows viene visualizzata quando si esegue o si apre un file che Microsoft non riconosce come un file attendibile. Il file è bloccato a meno che tu non specifichi specificatamente a Windows che il file può essere eseguito o aperto.

Se hai scaricato un file da un’origine attendibile e lo esegui spesso, puoi sbloccare quel file in modo da non ricevere l’Avviso di sicurezza finestra di dialogo ogni volta che lo esegui.

ATTENZIONE: assicurati di sbloccare solo i file che conosci provenire da fonti attendibili. Lo sblocco di file sconosciuti può aumentare il rischio che il tuo computer venga infettato da malware o virus.

Come sbloccare un file direttamente nella finestra di dialogo Avviso di sicurezza

Il modo più semplice per sbloccare un file è una casella di controllo nella finestra di dialogo Avviso di sicurezza scatola stessa. Quando appare l’avviso di sicurezza, deseleziona la casella “Chiedi sempre prima di aprire questo file”. Quindi, fai clic su “Esegui” o “Apri” per avviare o aprire il file.

NOTA: questo metodo sbloccherà un file in qualsiasi posizione sul PC.

Ho una domanda: perché hai installato così tante app su Android TV? Sai, così tutte quelle cose che hai installato “solo per provare”, quindi non sono mai stato usato di nuovo? Sì, quella roba.

Windows 7, Windows 8, 8.1, 10 e Vista includono una funzionalità integrata in Gestione disco per restringere ed espandere le partizioni. Non sono necessarie altre utilità di terze parti! Vale la pena notare che molte utilità di terze parti saranno più ricche di funzionalità, ma è possibile eseguire le operazioni di base in Windows senza aggiungere nulla di nuovo.
