Is this why maybe "Checking for Updates" never finishes, or that when Windows Update is opened or opens on its own, that it may tell the user, "All Up To Date"? or No New Updates Available?
I have been looking through this site, https://www.microsoft.com/en-us/search/downloadsdrillinresults.aspx?FORM=DLC&ftapplicableproducts=%5e%22Windows%22&sortby=+weight&q=&first=337
page by page, and the most recent listings are from May 2016. NOTHING more recent found so far. We may be checking for updates and expecting to be told the list of updates available, but none have been issued. No sense checking for updates which do not exist.
