Some people are worried about losing the ability to use the old Windows 10 Start Menu in the Windows 11 Upgrade.

There is a way around using the new Windows 11 Start Menu by doing the following:

  1. Open Regedit
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Explorer\Advanced\
  3. Create a new DWord called Start_ShowClassicMode
  4. Set its value to 1.

Hopefully, Microsoft will make a switch in a later, or final version, so users can choose which Start Menu they like to use. Doesn’t seem a big issue to do this.
