I did something bad today. I followed an article which I cannot locate now but it asked me to add Permissions to the HKEY_CLASS_ROUTE... to be honest I am in such a mess at the moment, I can't recall which user accounts they were. I think it was Administrator.
Anyway, now I can't access pretty much most things on my Vista PC since then. All file associations have gone! Even .REG.
Does anyone have any simple suggestions to get EXE associated again so that I can run a registry fix program?
