I’ve seen recently on several Windows 7 computers the following message when you try and run Windows update.
“Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer.”
On further inspection the service is running and everything looks to be as it should be.
The problem appears to be that Windows Defender hasn’t run a scan for several weeks. Once you have run Windows Defender and completed a Quick scan, Windows Update starts working properly again.
In my case the machines were spare Windows 7 machines that only get used for a couple months every year.
