Windows 7: Program Compatibility Assistant - Enable or Disable

Hello OpTicaL,

I would recommend to use either the REG file or Group Policy in the tutorial. The REG file does the same thing as Group Policy, but I just added it for those that do not have Group Policy in their editions of Windows 7.

Can someone tell me what the default setting for the Program Compatibility Assistant Service is? I was thinking about turning it off so I disabled it but then decided against it and now I can't remember what it was originally set to. I checked Program Compatibility Assistant Service | Black Viper | www.blackviper.com and it says Win7 Ultimate's default setting is Manual but I have a feeling it's supposed to be Automatic or Automatic (delayed start). Can anyone who has Win7 and hasn't messed with the setting yet tell me what it was set to?

Hello Chillz,

The default setting for the service is Started and Automatic.

Quote:
The Diagnostic Policy Service (DPS) and Program Compatibility Assistant Service must be set to Started and Automatic in Services for the PCA to be able to be enabled and to execute.

Rather old post but sometimes old info still works!

On W10TP and tried the Group Policy method. There's a note that states not in this windows version on the final page. I disabled, rebooted but still got the PCA. Would the registry method work?

Hello Bill,

In Windows 10, you would need to use the Group Policy location below instead in OPTION TWO, then use the same steps.

Computer Configuration, Administrative Templates, Windows Components, and Application Compatibility.

I tried that first but still got the PCA blocking an install. There's a note on that final enable/disable page that states that it's not supported in this Windows version. Wonder why they'd have a page to make a change yet it's not supported?

This what it states:

This setting exists only for backward compatibility, and is not valid for this version of Windows. To configure the Program Compatibility Assistant, use the 'Turn off Program Compatibility Assistant' setting under Computer Configuration\Administrative Templates\Windows Components\Application Compatibility.
