Windows 7: removing program compatibility assistant changes?

removing program compatibility assistant changes?

Microsoft's Program Compatibility Assistant popped up and made changes to my system after a photoshop cs6 crash. Since the PCA, according to MS, is designed to make older programs compatible to MS's newer O/S's, and since my version of photoshop was created long after win7, am I correct in concluding that PCA's changes to my system were unnecessary?

If I am correct, I want to remove any and all changes PCA made. From what I've read online, it seems that all changes are only made to the following registry key and that no other microsoft program or service changes or adds values to this key?

HKLM/software/microsoft/windows nt/current version/AppCompatFlags

If that's so, is it safe to delete the value for photoshop in this subkey:
HKLM/software/microsoft/windows nt/current version/AppCompatFlags/Layers

And do I need to delete the value for photoshop in this key, which seems to be for styli and pens, which I may get sometime in the future and since it's so specific doesn't seem as if it would interfere with using photoshop with a mouse:

HKLM/software/microsoft/windows nt/current version/AppCompatFlags/PenService

Thanks for any help.

Hello Ellen,

Yes, you could safely delete those values in that key to no longer have them run in compatibility mode. Using OPTION THREE in the tutorial below as a guide, there's also the same location in HKCU that may contain these values.

Compatibility Mode

Hope this helps,
Shawn
