Hi,
I faced a similar issue! The following worked for me
- Right click on the Start Button and select "Run"
- Type "regedit"
- Navigate to HKEY_CURRENT_USER>Software>Microsoft>Windows>CurrentVersion>Explorer>Advance
- Create a new DWORD (32-bit) value, call it "EnableXamlStartMenu"
- Restart Explorer from task manager.
Hope this helps!
