After creating a fix in the Compatibility Administrator, we can go to File menu
-> Install
to install it.
My question is how can we undo this and restore the system to the old state?
I believe the install
makes some changes to registry, I can search the GUID and it's in many places. I don't know if deleting this GUID all over is good idea because there may be other changes too. I hope there is a better way.
