I accidently replaced all security principles on my user folder. Now my metro apps are not opening as I replaced security principles of their local data folder located at %UserProfile%\AppData\Local\Packages. How can I reset these security principles.

Note:

Adding "ALL APPLICATION PACKAGES" to security principles is working. But I want to replace it with individual metro app id for security reasons.

What are needed:

1-> individual App's uid 

2-> adding to folder using powershell or cmd as GUI may not work.

See image for clarity.

Thank You

Hi,

Generally speaking, system restore would be an efficient method to resolve this problem, please have a try.
