Windows 11 Upgrade on Unsupported Hardware

Windows 11 normally requires both SecureBoot and TPM 2.0 in order to be installed on a computer, but using the following steps you can perform an in-place upgrade on a Windows 10 or Windows 11 machine that is running unsupported hardware.

• Download the Windows 11 iso you will want to be installing (they are pre-downloaded on the PC Tune Up USBs in the PC folder).
• Double Click the .iso file to mount it.
• In the folder it opens (likely something ala CCCOMA_X64FRE_EN-US_DV9), navigate into the “sources” folder.

Click up in the navigation bar so the folder path is highlighted. Type “cmd” and hit enter.

• • This should open a command prompt window with the first line showing something like, “E:sources>”.
  • If a command prompt doesn’t open, wait a few seconds and try again.
• In the command prompt, type “setupprep.exe /product server” and hit enter.
• You should see a window open called “Windows Server Setup”. Progress through the dialogue to install the OS making sure to select “Keep files, settings, and apps” and then it will begin installing the Windows 11 upgrade.
  • Don’t worry about the window being labelled “Server” or the installation dialogue mentioning Windows Server, when the install finishes it will have installed the same edition (Home, Pro, etc.) the computer was running before.

After the install completes, make sure to check for and install any available Windows Updates. Once those are all installed, run the Tune Up Utility batch file as well.
