Windows 7: Help I can't open folders!!

For some odd reason, I cannot open files. I double-click them and a message comes up (below). I even checked the folder options and it is set to double-click folders to open. The only way for me to open folders is to right-click and click open, but that's long.

Could anyone tell me how I can sort out my problem? I've tried system restore but that doesn't seem to work either, it corrupts my system so I undo sys restore.




"this file does not have a program associated with it for performing this action. Create an association in the set association control panel."

This is almost always the result of a virus on your system, as soon as you get them opening again you need to immediately run a deep scan.

Meanwhile look here
Default File Type Associations - Restore

Thanks that worked. Originally what happened is that my system installed windows 7 SP1 and all of a sudden this started happening. Then I removed it. System was still messed up and your thing fixed my problem. And I guess I'll do my virus scan now just in case one sneaked by MSE.

Ah so it was a failed sp1 installation, I suppose that could do it too.
A lot of things are changed during that upgrade so if it didn't go right I suppose that could have been the source of your issue.

alright well thanks anyway. and No virus anyway either.
