I have the same problem that I recently discovered when I tried to do a specific search. This was not like that before. This just appeared after a certain upgrade, I don't know which one 'cause I don't keep track of them, there are so many.
Are these "Independent Advisors" on this forum payed my Microsoft in any way? Because if they are, their work and the also work of all MS tech support engineers who write articles on the MS Support site is absolutely pathetic.
For any issue that someone has with Windows, and this since Windows 8, the first answer that tech support gives you is: run the System File Checker tool (SFC.exe) (see the copy and paste answer of Joseph Y. M.) This is totally totally useless.
This kind of answer is as good as the built in Windows troubleshooter, a waste of time.
It is unbelievable how it is possible that Microsoft can allow this kind of obvious bugs.
I am wondering myself if these so called MS tech support people they have themselves Windows with the latest official patches?
If they do they can simply try to find the Search Tools and Menu on their own computers before providing these "copy and paste" answers....
Shame on you Microsoft.
