Blocked by Group Policy message after Reinstalling OS

Hello,

I've just got my computer back after reinstalling Microsoft OS, and I'm currently installing my old programs. However, some programs/functions are blocked by group policy/admin. It seems like the policies may have been modified by default when the OS was reinstalled.

I am the owner/admin, personal home computer, private network, not part of domain.
I've tried some methods mentioned in other threads such as running as admin, changing security policy to prompt for credentials, checking blocked programs in AppLocker.

There is one method I've been looking into before using, which is going into regedit and deleting some registries, but I've read that deleting the wrong file can wreck the OS. I'm hesitant about this because I'm not very proficient with computers.
Are there other solutions to this issue?
If not, perhaps someone could provide advice on how to modify registries.

Where have you obtained this Windows OS from and what media are you using to reinstall it?

It should not throw warnings that items are blocked by GPO on a clean install of Windows 7 Professional x64.

Try following the instructions in this awesome thread:

And see what turns out. Report back.

A computer repair service reinstalled the OS for me. I'm not sure if he used a different cd-key or version from what I had previously, but I did not have these restrictions before the re-install. When asking about the install, he said he uses the same install media and method for all computers he services, so perhaps he set these restrictions as a default? Not quite sure how it works.

I've tried the first two options, both didnt work. However, on the second option, cmd showed that C:\windows\system32\grouppolicyusers and C:\windows\system32\grouppolicy could not be found.
I don't have an installation or repair disk, so I was not able to try the third option.
I've tried manually setting the group policy earlier as advised by another thread, but that method didnt work.

Is there another method to return policy settings to default?

Is it safe/possible to try the third option (using command prompt at boot) without an installation disk?

You can try to use a USB device to boot into as Windows Installation Media.

Attempt running this command in an elevated Windows Command prompt:
