PCA Go figure

Program Compatibility Assistant
I'd love to post an good explaination on this one but I haven't found one.  The best I've got is:

Key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Name:
Path to exe            - Type REG_SZ

Data
VISTARTM         - This is the PCA mode to use. RUNASADMIN can also be used where necessary.

Setting the path to an exe with VISTARTM will stop PCA popping up and annoying you.

You can try this if you like - good luck
