Fix windows has blocked this software because it can’t verify the publisher

Security is perhaps one of the most important characteristics of any computer operating system. For example, Windows has a per-program publisher verification policy that only allows files from verified sources. The rest of the software will constantly require confirmation because of this. We will guide you on how to disable the “Windows Has Blocked This Software Because It Can’t Verify The Publisher” popup in Windows 10.

How to fix windows has blocked this software because it can’t verify the publisher

In fact, each program has its own digital signature, which stores the version, developer, and other information that is more important to administrators than users. Adding this signature is only half the problem because it needs to be verified, in other words, officially confirmed.

To do this, the developer needs to collect a thick package of documents and coordinate the program with Microsoft so that it adds it to the database. The base, by the way, is updated along with Windows updates. If the developer does not follow this confusing algorithm, then his software will constantly open along with a warning notice.

The easiest way to solve the problem is to download software only from the Microsoft Store service because all applications go through preliminary moderation there. Only the service works extremely “crookedly”, and its base is relatively small. That is why we offer alternative solutions.

Although the user is not able to send the file for verification for the publisher, he can do the opposite – prohibit the OS from verifying the digital signature or forge it. Below are some basic tips on how to do this. Some of them require the installation of additional programs.

file unsigned

There are many programs for removing digital signatures, but we recommend focusing on this one because the utility weighs little and also instantly performs the only task. Action algorithm:

  • Download the archive with the required file from the official site.
  • Unzip it anywhere.
  • Create a shortcut on the desktop with the executable file.
  • Drag any file to the program’s shortcut.

The utility will automatically “remove” the digital signature from the file. The next time you start, you won’t need to confirm the installation. The method is only effective if only one file needs to be modified or run.

Disabling UAC

This method works more globally, literally preventing Windows from checking all executable files. With the help of “User Account Control” the user can reduce the degree of control to its complete absence. For this you need:

  • Open control panel. This can be done through the search or the System folder.
  • Open the “User Accounts” section.
  • Select a subsection with the same name.
  • A window with a vertical slider should open. We lower it to the very bottom, to the item “Never notify”.
  • Click OK.

Now Windows will open any files, regardless of the publisher. Be extremely careful, because now some programs can open on their own, without your knowledge.

Configure security policy settings

The result of this method is not very different from the method above, but still worth a separate review. To open a local policy and edit it, do the following:

  • Open the Run window by pressing Win+R.
  • In the application that opens, enter the command “gpedit.msc”.
  • In the left navigation menu, open the sections in the following order: “User Configuration – Administrative Templates – Windows Components – Attachment Manager”.
  • Locate the “Default risk for attachments” item and double-click on it.
  • Move the switch from “Not configured” to “Enabled”.
  • Add permissions for files that you want to open without checking.
  • Click OK.


Opening a file via command line

Next in line is a method for ardent fans to perform any task through the terminal. First of all, we need the console itself. It can be opened through the keyboard shortcut “Win” + “X” or through the search. It is necessary to run the utility as an administrator, otherwise nothing will work. In the open console, specify the full path to the executable file. Done, the file will run without restriction. Alas, this method will have to be used every time you start.

Value Changes in the Registry Editor

Everything that can be changed in the system can definitely be found in the registry, disabling publisher verification is no exception. We recommend that you skip this method if you are afraid of doing something wrong. The registry is a rather fragile tool that should not be played with. Action algorithm:

  • Open the Run panel by pressing Win + R.
  • Enter the “regedit” command.
  • If necessary, enter the administrator password in the window that appears.
  • Expand the sections in the following order: “HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Associations”.
  • In the “Associations” section, create a string value called “LowRiskFileTypes”.
  • Set the value to all file types.
  • Click the “Ok” button.

Ready. Now the OS will not scan files with the selected resolution.

FAQs on windows has blocked this software because it can’t verify the publisher

How do I unblock unverified publisher?

If you’ve tried unsuccessfully to unblock a publisher that you know is not verified, there are a few things you can do. First, make sure that the publisher is actually blocked. If it’s not, there may be a configuration issue with your account or a firewall blocking the publisher’s access. If the publisher is blocked but you still want to try unblocking it, first contact customer support and ask them to remove the block. Finally, if all else fails, you can try using a proxy server or VPN to get around the blocks.

The badge indicates that the publisher has met Microsoft’s high standards for content quality and accuracy.


In conclusion, it is clear that windows has blocked this software because it can’t verify the publisher. While there may be legitimate reasons why a user may want to install software from an unknown or unverified publisher, in most cases this is not advisable. In order to protect your computer and your data, it is best to only install software from publishers that you trust. If you experience problems with a program that has been blocked by Windows, you can try troubleshooting the problem or contact Microsoft for assistance.
