Hi
Recently we are facing one issue related to the Windows 7 clients. Some of the Windows 7 Clients are not able to install the update when we deploy the Software Update.
Windows update log shows detected the updates but not able to install the same. so please let us know the resolution.
Action taken so far : Reinstalled the WSUS and Reconfigured the SUP also.
