Hi Jeff,
Refer to the following methods and check if it helps:
Method 1: Run System File Checker tool.
Use the System File Checker tool to repair missing or corrupted system files

If the issue still persists, go to method 2.
Method 2: Scan and restore the operating system files health then check if you can open the Regional settings.
a) Press “Windows Key + Q” to open Charms Bar.
b) Type “cmd” without quotes in the search box.
c) On the left pane, right click on the “cmd” option and select “Run as Administrator” on the bottom menu.
b. Type the following commands in the command prompt. Press Enter after each command.
• DISM.exe /Online /Cleanup-image /Scanhealth
• DISM.exe /Online /Cleanup-image /Restorehealth
c. Close the command prompt.
Check if it fixes the issue.
Try these steps and let us know the results.
I have the same issue and after a day of my PC being idle, when I move the mouse/press a key on the keyboard it is non-responsive. In the event log, the last entry before my reboot (can be several hours inbetween) is EventID 10010.
I tried to run the above command but get the following error:
C:\Windows\system32>dism.exe /online /cleanup-image /scanhealth.
Deployment Image Servicing and Management tool
Version: 6.3.9600.17031
Image Version: 6.3.9600.17031
Error: 87
The scanhealth. option is not recognized in this context.
For more information, refer to the help.
The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
Please help, Windows 8.1 is proving to be unstable :(
