Hi Davidhart711. :welcome:
Hence, is the problem skype (that doesn't work)?
Or what?
And if it's skype, did you already try to reinstall it?
If no, you could try now.
If yes, right-click the windows button at bottom-left corner, click
command prompt (admin), a black screen should appear, write in it
sfc /scannow, press enter on your keyboard, wait 15-50 minutes whilst the task completes, post its final result here.
In the meanwhile, you can read
Use the System File Checker tool to repair missing or corrupted system files (click).
Finally, if the result will be
Windows Resource Protection did not find any integrity violations., it should mean you have no problems (from SFC point of view).
If the result will be
Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log., it should mean you had problems but they have been corrected.
If you have a different result than those two above, probably this topic will be moved to the windows update sub-forum.
