I have been trying to update Windows 7 Home Premium x64 but after several hours it remains 'Checking for updates...'


I have uninstalled all virus protection software

I have tried turning automatic updates off, rebooting then back on.

I have tried disabling non Microsoft services and startups

I stopped the appropriate services, deleted the cache, re registered the DLLs

I did an inplace update of Windows

I restored the image I took a couple of days ago then asked the already downloaded update to install - that too stalled.

Most recently I have downloaded a fresh copy of the .ISO and burnt it to a USB stick, then replaced the disk drive and did a fresh installation to that.


I looked in the event log and see that "Failed extract of third-party root list from auto update cab at: <http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab> with error: A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file."

I see that my system clock is set correctly. I have deleted all the url cache entries.


I can reach any website I try, and other (admittedly not Windows 7) PCs will update fine through the same router.


The idea bin is now dry and suggestions would be appreciated.
