Compatibility Troubleshooter Broken

Hi all, first time posting here

I am on a Dutch Windows 10 Pro install

I`ve been having this problem for a couple of days

When I run the Windows 10 Compatibility Troubleshooter, it seems to hang on the detecting issues screen. It used to take some seconds before the next screen would appear, but now it just stays on this screen forever...

I have run the sfc /scannow command, but that does not fix it

My Windows Version number is 1909 (18363.836)

I hope someone can fix this please

Hi, do you see the progress bar continuing to move during this time?
The time it takes may depend on the complexity of the program.

Here's what you might see in the task manager while it's actively scanning:


What do you see as you say


- does the task manager show the process actively using CPU time if you leave it running long enough, or something else?

Please try this diagnostic step:
Create a new user for test purposes. Log in as that user and try the troubleshooter and report the outcome.


- what happened a couple of days ago?

Did you
- install something
- uninstall something
- receive an update
- make some other change?

Do you have a System Restore point created before this started to happen that you could use?

Hi, thanks for helping me out

I have updated W10 to 2004, but the problem still persists.

When I run taskmanager there is no activity regarding the Diagnostics troubleshooting wizzard, it has 0% CPU use. After a minute it has a 0,1% use...

I restored the system from a restore point yesterday, to a date when it still worked, but that did not fix the problem..

I also created a new user, and tried to run the program, but no dice...

Odd- so something common and not 'Windows' as you've upgraded.

What happens if you boot to Safe Mode and run it? (It should).

Have you tried it with different exe files or shortcuts?

In normal mode, try using Shellexview (free) to disable non-MS shell extensions (no need to log off).

It works in safe mode!
