yesterday I installed the Creators Update with the Windows Upgrade tool. The installation process did go through flawlessly.
However, after the installation all my programs went missing from the start menu with the exceptions of the "stock" apps and those apps I installed from the MS store (such as Facebook, Twitter, etc.)
The program shortcuts are still there. They are in the proper place in \ProgramData\...
The programs also show up in "Programs & Features" --- so they weren't uninstalled during the upgrade
ClassicShell finds the programs just fine. The programs can be started just fine.
It's the Windows start menu that refuses to display them.
What can I do?
