From another forum he suggests opening an administrative command prompt and run:
sfc /scannow
sfc scans protected system files and replaces bad/missing files with windows versions. And the person with the issue claimed that it works, so try that first.
I found that page after going through the process of creating them manually.
To create them manually:
Create a new folder on the desktop (just for organizational purposes and ease of moving them when done)
Right click - New - Shortcut
Paste the path (list included below)
Next
Paste the name
OK/Done/whatever it is
You'll need to repeat that for each shortcut.
When you're done:
Select All (all of the shortcuts)
Navigate to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Administrative Tools
Paste
OK the UAC popup
Now your Control Panel - Administrative Tools should show up and work properly.
Administrative Tools windows 8.1 missing
