  1. 1 First, verify that the update you're trying to install is still available. Go to the Microsoft Update Catalog website (catalog.update.microsoft.com) and search for the update by its KB number. If it's not listed, it may have been replaced by a newer update.
  2. 2 If the update is available, try downloading it manually from the catalog and install it by double-clicking the .msu file. This bypasses Windows Update's online check.
  3. 3 If you're using Windows Update for Business or WSUS, ensure your server has synced the latest updates. Contact your IT administrator if needed.
  4. 4 Clear the Windows Update cache: Stop the Windows Update service, delete the contents of C:\Windows\SoftwareDistribution\Download, and restart the service. This removes any corrupted download data.
  5. 5 Restart your PC and try checking for updates again.
