I set Roxio Backup to do a backup of mydocuments every Friday. When my computer started doing strange things yesterday, I rebuilt in. After quite a long while trying, I finally managed to find the 'Launch_Retrieve.exe' file (I backed up to an external hard drive). There's a fle in my backup (about 2000 out of 4100) 'windowsupdate.log' that it keeps on getting stuck on. Any ideas as to why this is happening?
