User Account Control, or just UAC is a part of the Windows security system which prevents apps from making unwanted changes on your PC. When some software tries to change system-related parts of the Registry or the file system, Windows 10 shows a UAC confirmation dialog, where the user should confirm if he really wants to make those changes.
Thus, UAC provides a special security environment for your user account with limited access rights and can elevate a particular process to full access rights when necessary.
Once you disable UAC, you cannot run Universal apps, previously known as "Metro" apps in Windows 8. All apps installed from the Store, Settings and also the Windows 10 Start menu will not work without UAC.
Windows 10 Creators Update changes this situation. Windows 10 build 15063, which was confirmed today as the final version, finally allows you to use UWP apps even with UAC disabled.
I disabled UAC completely using Winaero Tweaker and restarted Build 15063. All Universal apps still work!
To disable UAC in Windows 10 Creators Update, you can do the following.
- Open Registry Editor.
- Navigate to the following Registry key:
If you do not have such a Registry key, then just create it.
Tip: You can access any desired Registry key with one click.
- In the right pane, modify the value of the EnableLUA DWORD value and set it to 0:
If you do not have this DWORD value, then create it.
- Restart your computer.
Alternatively, you can open the classic Control Panel and go to Control Panel\User Accounts and Family Safety\User Accounts. There you will find the link 'Change User Account Control settings'. Click it.
In the User Account Control settings dialog, move the slider to the bottom (Never Notify):
Click OK and restart Windows 10. This will disable UAC.
Tip: See the article How to turn off and disable UAC in Windows 10.
