Windows 10: Problem with the task bar, security center, action center and start menu maybe others too

Hi,

I'm currently troubleshooting a laptop of my brother. Windows 10 family with alll the latest update

He decided i don't know why to mess with the security setting autorisation, access, ownership... of his hard drive.

And he ended up with an unopenable start menu and action center, the security center doesn't open too, he can't right click on the taskbar, the search bar doesn't respond, the user creation doesn't show, and the list is long. I can lauch game and use any 3rd party software without any problems.


I managed to install a dual boot to check, everything work but i can't access any hard drive or lauch any 3rd party software games, webrowser...

I followed the step given here :

here


here


and here



Without results.

I wanted to do a clean install but he doesn't have anywhere to store his data over 2TB of stuff.


Is there anything i can do?

If you need more information i can post it...


Best regards ^^

Accent color for start, task bar, action center

 

Disable Action Center in Windows 7?

Unfortunately that doesn't disable Action Center, all it does it cause Acution Center to bitch about the Security Center service not running.

Action Center seems to be a different beast from Security Center...

And telling it to not display any messages gets it out of the way, the same way disabling the icon in the suggestions above does, but Action Center is still enabled and running.

 

Action Center and Start Menu Continually Fail


Device: Surface Pro 4
OS: Fully Updated Windows 10

Issue: Action Center and Start Menu continually fail.
Symptoms: After an unpredictable amount of time, Action Center and Start Menu will not open using multiple prompts. Action Center will not respond to taskbar link or swipe from the right and Start Menu will not respond to task bar click or keyboard button.

Troubleshooting:

• I have done several SFC scans (the first few found stuff and repaired it and subsequent runs find nothing)
• I've done the DISM image restore health hocus pocus to no avail.
• I've executed "Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }" in an elevated powershell. This works, until it doesn't.

EDIT: Nothing is working now for troubleshooting. Going to try a restart and see how long until it happens again.


​None of these are permanent solutions. Any ideas as what is causing this and how to stop it from happening?
