Vista - Windows Update not loading

When I click on Windows Update, it just hangs with the circle cursor spinning. All that opens up is a white box, and nothing happens. I had no issues running Update 2 days ago. It just started this yesterday out of the blue.

IDK if it is related, but I also can't update drivers in Device Mgr. It just keeps searching the web for drivers, and nothing ever happens.

1.Run cmd.exe with administrative previlliges (right click on this file as admin) and type

sfc /scannow

2.Re-register WU:How do I reset Windows Update components?

Have u tried system restore to an earlier point?

Not yet. I thought of that this morning, but I have to wait until I get home to see. If some of the other suggestions do not work, then I will try system restore.

I understand my post 2 don't help -right? Uninstall all protected software -firewall,antivirus,antispyware.Try also this tool Description of the System Update Readiness Tool for Windows Vista, for Windows Server 2008, for Windows Server 2008 R2 Release Candidate, and for Windows 7 Release Candidate
If really nothing help you have probably trouble with CBS keys -and use System Restore

I did try the sfc/scannow, but it did not find any errors. I then tried the FixThis download, which allowed me to access WU, but it would not download. It just sat at 0% for about 10 mins before I quit.

I then did a system restore. After about 30 minutes of running system restore, there was no response. I thought it froze up as System Restore has never taken that long, so I powered off in the middle of system restore. Not a great idea. Registry was corrupted. Luckily, I switched the 1st boot device to the CD/DVD ROM in BIOS, and re-installed Vista clean from scratch. Now everything is fine, and the system is up and running. I just hope I don't encounter this issue again.

Thanks for all the help to everyone.
