Running Windows 10. Survived a failed May 2019 Windows update. Trying to uninstall all 3rd party apps before update runs again. Speccy throwing multiple werfault.exe errors and will not uninstall.
CCleaner is also throwing werfault.exe errors when attempting to uninstall. Unable to uninstall.
Can you confirm your versions of CCleaner and Speccy? Also, what are you using to uninstall the apps? Windows uninstaller or the uninstaller in the CCleaner > Tools menu?
I usually use Option 6 described there - the 'Hard Reboot' option using the power button.
Use the power button to turn on, then turn off again before it gets to the login screen, doing that 3 times should boot into Advanced Startup.
(But you should read the other options as well, it's always useful to know about the other Advanced Startup options).
