Windows Stops Recording Run History (Run MRU list)
When opening Run via 
+R in Windows Server 2019, there are no items in its history or Registry key: (I believe the situation is the same in Windows 10)
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\RunMRU
- I think it's because I deleted a folder in one of the Windows system directories, and while I can't think of the exact name of that folder, I remember its name contains
history
Is there a way to fix this?
You need to run Settings > Personalization > Start, then enable the option of "Show most used apps":
If that doesn't fix the problem, use regedit to navigate to the key
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced.
Ensure that the DWORD value named Start_TrackProgs is set to 1.
