I have a patch policy that searcges for critical and recommended patches for Microsoft products. It runs at 1 pm each day. When I look at the windows update history on the control panel of the pc it shows almost all of the patches as being installed on the day the policy was run. In some cases over 80 patches are being reported as installed that day even though the patches are over a year old. I also have a lot of error messages as the pcs seem to be trying download patches that are not applicable for the o/s. Also since 2017 update 2a quite a few of my pcs are freezing and locking up after the policy refreshes.
