Recently all my windows updates are failing to install. They download fine and then restart my pc to install. The PC locks up about 12% during the install process, then fails, and reverts to old settings. Any suggestions?
could be a hardware issue? Maybe problem with the HDD or Operating System is corrupted. You may need to try to reinstall the OS and then see if it happens again. It has happended to me once before turned out that my OS was corrupted. Remember to backup your data before you try to reinstall your os.
Try installing an Anti - Malware software, scan and clean. Then try again. Sounds to be some drivers are jammed and would be fixed when you remove those malwares/trojans, also check if this is due to KB2800095 update.
