Stumbled upon your remarks after having fixed the same problem: Windows Update not working but no Virus found by NEP or One Care, tried a lot but nothing worked until I discovered %fystemRoot% in Registry entries for Intelligent Updater and Wuauserv under HKLM\SYSTEM\CurrentControlSet\Services Managed to clean them in normal environment but had turned off automatic updates, and deleted CatRoot2 and let Combofix do its work. After that, ran WinUpdate again manually which worked, turned it to automatic after the first 7 updates and now it is still working.
