How to Unblock a File on Windows 10

Windows 10 can prevent you from opening files that it considers as a threat. More often than not, .reg files. If you want to unblock a blocked file, then you’ve come to the right place.

There are generally a couple of methods to go through this and we’ll look at both of them.

Unblock a File From Smart Screen

If your file is blocked by smart screen, right click on the blocked file of your choice, click on properties and on the bottom of the window click on the tick box which says Unblock”

Do keep in mind that you’ll need administrator permissions to do that. You don’t necessarily have to be logged in to your administrator account, but you do need to know the administrator password.

Unblock a File From “Open File”

With “open file”, every time that you open a program which needs to perform changes on your computer, you will be greeted with a warning which asks you if you want to really let that program run.

All you have to do in order to prevent “open file” from coming up every single time that you want to run your programs, is untick the “Always ask before opening this file” box.

This only works for one program at a time. So, if you want to apply this to another program as well, then you’re pretty much forced to repeat the process.

Unless you’re interested in completely turning off UAC which completely disables the “open file” warnings. However, do keep in mind that this is generally not recommended.

Even still, I’ll mention this and one more trick just in case that you want to take the leap of faith.

Trick 1: Disable UAC

If you disable UAC, then you’ll never see the warnings of the “open file” again. And the process of doing so is quite easy as well. Of course, you’ll need administrator permissions for this.

All you have to do is type “UAC” in your Windows search bar, run User Account Control Settings with administrator permissions, drag the bar down to never notify, hit OK, and you should be good to go.

Again, this is generally not recommended as it might decrease your overall computer security. If you wanna do it then do it at your own risk.

Trick 2: Use Power Shell To Unblock a File

Another way of unblocking a file is using the unblock command via Power Shell. Type “Power Shell” in your windows search bar and launch the program.

After that, copy and paste this command “nblock-file -path” and proceed to insert the file path of the file that you want to unblock. Easy.

Once again, you’ll need administrator permissions to perform this.

Why Would Windows Block a File/Program?

Mostly as a security precaution. It’s no secret that the internet is full of trolls, malware, viruses, scammers, hackers, you name it.

The more that you dwell on untrustworthy websites, the more likely that it is that you’ll experience a file block at least once. Especially if the programs that you’re downloading mess with your system files in any way.

Unblock file in Open File – Security Warning box does not have the options stated above! Windows Smartscreen doesn’t open!! Checking the unblock box blocks the file completely!!!!!!!!!

None of the above are helpful, even when all files are unblocked manually, the application will not load……
