Windows 11: can't open anything as admin, I'm stumped

Hey everyone, I'm stuck on something weird and could use a second pair of eyes.


I'm definitely an admin on my PC, but the moment I try to open anything as admin (Task Manager, cmd, PowerShell, Event Viewer...) I get "An administrator has blocked you from running this app." No UAC prompt (Yes/No), it just closes immediately. Non-admin, everything opens just fine.

I've already checked a bunch of stuff (group policy, registry, AppLocker, IFEO via Autoruns, the AppInfo service, leftover Avast bits): nothing unusual anywhere. An sfc /scannow found 462 corrupted files but none related to the blocked tools. ESET caught a suspicious .exe and quarantined it, but it had never been executed, and nothing changed after removing it + rebooting.

The weirdest part: I can't even read the event logs from the command line (wevtutil), "Access denied" on Application and System, which shouldn't happen to anyone normally.

If this rings a bell for anyone, I'm all ears!

We need you to enable Admin account to work on troubleshooting the problem.

This video guide provides a detailed walk-through on enabling the built-in Administrator account using Hiren's BootCD.

How are you going to install the program and use it with administrative privileges if you don't have that option?

This guide will show you how to enable the hidden built-in Administrator account from Windows Recovery Environment.

That's quite a few...

I would keep running it until it finds none.

Failing that, you might have a corrupt user profile.

Create a new admin account, and see if that works.

So is the Media Creation Tool ISO...


In-Place Upgrade -

Download, mount the ISO, open an elevated Command prompt, and cd to the drive letter of the mounted ISO.

On supported hardware -

Run setup.exe

On unsupported hardware (bypasses checks) -

Run setup.exe /product server

Done.
