So far, many times I’ve found this strange error in Windows Update center stating that “Windows could not search for new updates”.
The reason is your pc is configured to access a WSUS Server that, for some reasons, isn’t accessible.
First question is: what is WSUS (Windows Server Update Services)?
WSUS or Windows Server Update Services is a free patch management tool available to Windows Server administrators allowing them to authorize, publish and distribute updates within a network (most of the times inside a domain).
Anyway, second (and most important) question is: how I can solve that error? It’s quite simple, following that procedure:
- Open registry editor (Start menu –> Run –> regedit)
- Find the following path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
- Chage the value of the UseWUServer from 1 to 0 (double click on it, change the value and click OK)
- Restart Windows Update service (Start menu –> Run –> services.msc, find the Windows Update service and click on Restart)
That’s all. Now you can download updates again.
EDIT 28/08/2013: On Windows 8 I’ve also experienced a different solution. From command prompt (as admin) type “netsh winhttp reset proxy” and then re-check for updates.
