Vista - New buggy updater

Hello!

I noticed that several weeks ago Microsoft changed the old good Updater to the new buggy one.

Sometimes I cannot install updates because I cannot select them! See the screenshots.

Week ago my hard drive died, so I bought new and reinstalled everything. Fresh system with old Updater updated well, but then new updater installed, and bug returned

Please help me to fix it. I cannot fix by myself because I have no source code of Updater (Microsoft does not publish source code of their products for unknown reason).

Try a couple things:

1.Try reinstall Windows Update Agent How to obtain the latest version of the Windows Update Agent to help manage updates on a computer
2.Try reset the whole WU in aggressive mode How do I reset Windows Update components?
3.Try BITS repair An update is available to fix a Background Intelligent Transfer Service (BITS) crash on a Windows Vista-based computer
4.Run cmd.exe with administrative previlliges (right click on cmd.exe as admin) and type:

fsutil resource setautoreset true C:\

+restart

Thank you for this information.

I already said that reinstall of the whole OS did not help since the new version of Updater is downloaded.

I found a simple solution that work for me: reboot. After the reboot I CAN select which update to install (list is not empty).
