Windows Program Compatibility Assistant can be a real pain in the ass when you often use programs, scripts or applications that runs just for a second or two and then terminates itself. It can be also painful, when you run some software by a mistake and quickly close it right after starting. In each such scenario you’ll be nagged with a stupid message asking, if you want to run this program again.
To completely disable Program Compatibility Assistant follow these simple steps:
- Run Registry Editor (regedit.exe).
- Navigate to
- Create new key named
DisablePCAof dword type and give it
Or… save the following code as a .reg file somewhere:
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\AppCompat] "DisablePCA"=dword:00000001
Then double-click saved file and confirm addition to Windows Registry.
