Hi, Klauwaart
I'm really sorry, I really realize the importance of the start menu when you say that, a lot of approaches need to revolve around it.
For the uninstalling of updates mentioned in method 1, you can right click on the start menu and select Display settings, which also opens the settings screen, and then follow the steps.
For the restore operation mentioned in method 2, you can also open the settings via Display settings.
- Select System > Recovery > Advanced startup > Restart now
- Select Troubleshooting > Advanced options > System restore
It should now operate smoothly, if you have any questions, feel free to let me know.
