sdclt.exe is the Windows Backup executable. Do you use Windows Backup? If not, disable. If you do use it, you might want to either run "sfc /scannow" or do a System Restore.
I do use windows backup..or at least I try to..
I ran Scannow and it found nothing. I am not sure what system restore will do for me, as the thing has been a problem ever since I installed win 7..
I am stumped. However recently I just left the "starting backup" window open for about 30 minutes and it finally loaded. Once that happened, it worked fine. Go figure.
