Open up your control panel, then open user accounts. Click on user accounts, then click on manager user accounts.
Now add an account - give it full administrator priviliges.
Now what you can do is use the Windows Easy Transfer utility and save all your information to an external USB drive/key (do you have one?).
Once done - re-login with your new account and just transfer the files back using the windows easy transfer utility. It may say computer to computer - but you can easily transfer the information to the same computer.
Using this shouldn't copy the file association.
Orrr...you can just live with it it's not really that big of a deal - is it? Do you play around a lot with CFG files?
Lol..you dont need to reload windows....just reassociate the .cfg file with the program its MEANT to be associated with...
All the best Brett
Hey brett FYI - CFG files are not associated with any program (by default), and as i've stated already "You cannot change an association for a file type or protocol and leave it blank or disassociated. You must select a new program. "
And i've listed a few ways he can change it back without re-loading windows
For what it's worth... in the future change the .cfg file extension to .txt. Then edit the file as a test file in notepad, and save the .txt file. Then rename the file again, this time changing the extension back to .cfg. I know it's an old thread, but I came across it searching with Google as I'm sure other will. I just had to chime in and suggest people keep it real real simple. I hope someone finds the solution I'm offering here useful.
