I recently started having the common, as I realized, problem of not being able to rename folders in Windows 7 (32 bit). I don't understand why it happened after almost a year of ideal use of Windows 7. I haven't removed the libraries nor can I think of anything else that could potentially cause this, at least as far as I know. The only thing I did recently was to change my anti-virus program from the freeware version of Avira to the freeware anti-virus Microsoft Security Essentials. Any idea on what the problem is and how to fix this?
