There are many posts on the Internet about Start Menu Programs disappearing. However, none of those cases seemed to be exactly like what I'm experiencing. This has happened to me many times. I'm not sure what I did: the problem might've occured just after uninstalling some small video application, but might be unrelated to that. In any case, almost all items (.lnk files) have disappeared from my All Programs. So there are two locations for those files: C:\Users\USERNAME\AppData\Roaming\Microsoft\Windows\Start Menu C:\ProgramData\Microsoft\Windows\Start Menu The latter is completely empty (just a hidden desktop.ini left) and the former has some 2-3 misc links left, all others are gone. I just did a full undelete/recovery on my hard drive and it seems some of the new .lnk files, or copies of them, are found in a "Lost and Found" directory. Some or most of those deleted .lnk files are just ones I've moved/deleted by myself. So what exactly happened? If the cause is a bug in Win7, then fine, but I'd really like to understand what actually happened to the .lnk files. Did the Programs folder get deleted (by itself) or did some registry get corrupted and that corrupted the .lnk files beyond recognition or what. No, the .lnk files are not in recycle bin or moved to another folder (I searched everywhere).
