Windows 10 Pro Version 10.0.19042 Build 19042 control panel app will not launch

Maybe try launching PowerShell as an administrator, as in right-click and "Run as Administrator?" I don't know, honestly, but that seems like the best thing to try based off what response you're getting.

I feel so dumb right now! I had hidden the admin folder, so... yeah, permissions issues, I've restored the permissions, now the Control Panel is back!

Hi! LAByte

I'm James, An Independent Advisor, and I will help you with this issue

Actually the control panel is available for all versions of Windows, if your control panel does not start it is because you have some corrupted update files, you can try the following solutions:

Re-register all the store apps:

1. Press the Windows Key + R keys
2. Type powershell and press Enter.
3. Enter this command on the PowerShell and press enter:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

3. Restart and check if the issue persist.

Fix the Windows corruption errors with DISM & SFC tools.

This will help you to repair the Windows 10 system files and check for any issues, follow these steps below:

1. Open the Start menu, in the Search box type cmd or command prompt.
2. Right-click on the command prompt and select Run as Administrator.
3. When you Open it type the following command & press Enter:

Dism.exe /Online /Cleanup-Image /Restorehealth

Be patient until DISM repairs component store. When the operation is completed, (you should be informed that the component store corruption was repaired), give this command and press Enter:

sfc /scannow

4. When SFC scan is completed, restart your computer.
5. Try to update your system again.

Note: Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If you need more help with this issue, just let me know and I will help you.

I'm glad that the problem is solved, have a great day and a happy December!
