Get Windows 10 Context Menu in Windows 11

Open Command Prompt and run bellow command. and reboot the computer or go to task manager and restart “windows explorer” process

To Get Old Context Menu:

reg.exe add “HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32” /f /ve

bypass Windows 11 TPM 2.0 requirement

UPDATE 2023-November

HUGE GROUND BREAKING DISCOVERY! To ALL users that don’t meet the artificial requirements for Windows 11, I GOT SOME GREAT NEWS TO SHARE! When adding “/product server” switch to setup.exe in the Windows 11 setup directory, it BYPASSES the Windows 11 hardware requirement checks.

Method: Modify Registry

This method involves simply editing Windows Registry during the installation process of the new operating system. On unsupported devices, if you try to install the new OS, a message will appear on your screen stating that the computer isn’t compatible.

At that screen, you need to press Shift+F10 to open Command Prompt window and modify the registry. In Command Prompt, you need to run regedit.exe and create a new key “LabConfig” under HKEY_LOCAL_MACHINE\SYSTEM\Setup. In the “LabConfig” key, create two new entries:

  • BypassTPMCheck=dword:00000001
  • BypassSecureBootCheck=dword:00000001

Save the changes and compatibility errors will disappear.

Update | 2021 – October – 06

The fix itself is fairly straightforward too. Simply hit Win+r and type regedit to bring up the registry editor. Make your way to HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup and then right-click the main panel and create a new DWORD (32-bit) Value with a name of AllowUpgradesWithUnsupportedTPMOrCPU and set its value to 1
