Built-in Administrator account has no rights for some actions in Windows 10

Question

At some point I started getting following problems in Windows 10.

Microsoft Visual Studio 15 is showing the following error when I'm trying to run compiled Windows universal application:

Unable to activate Windows Store app ... The activation request failed with error 'This app can't be activated by the Built-in Administrator'

After trying to personalize Windows 10 desktop I'm getting the error message:

This app can't be open Settings can't be opened using Built-in Administrator account. Sign in with a different account and try again.

Few days ago everything was working fine with the same user account. How can I fix it?

Answer 1

The problem was related with User Account Control (UAC) settings. Some freshly installed software has disabled UAC.

Reverting UAC to default level and reboot helped me in both problems.

How to set UAC Settings

• Open User Account Control Settings by clicking the Start button, and then clicking Control Panel.
• In the search box, type uac, and then click Change User Account Control settings.
