Many PCs don’t meet the official system requirements for Windows 11. Most notably the infamous TPM 2.0 is often missing. Don’t worry: with a small fix, you can perform a Windows 11 in-place upgrade without TPM. In this guide, we’ll show you how to bring your system up to date using a CMD file and the official ISO, no TPM required.
A PC running Windows 10 or an older Windows 11 version
The latest Windows 11 ISO (download from Microsoft)
The file InPlace_fix.cmd (see below)
Administrator rights
Create a new file named:
InPlace_fix.cmd
File contents:
@echo off echo Windows 11 Upgrade Bypass get activated... echo Adminrights needed! :: Checks if the skript got executed as an admin. net session >nul 2>&1 if %errorLevel% neq 0 ( echo Please execute as admin! pause exit /b ) :: Regedit for AppCompatFlags\HwReqChk reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\HwReqChk" /f /v HwReqChkVars /t REG_MULTI_SZ /s , /d "SQ_SecureBootCapable=TRUE,SQ_SecureBootEnabled=TRUE,SQ_TpmVersion=2,SQ_RamMB=8192," :: Regedit for MoSetup - Bypasses not supported CPUs/TPM reg.exe add "HKLM\SYSTEM\Setup\MoSetup" /f /v AllowUpgradesWithUnsupportedTPMOrCPU /t REG_DWORD /d 1 echo Success echo Pleasse reboot system, before advancing. pause exit
Open Notepad.
Paste the content above.
Save the file as InPlace_fix.cmd (ensure the .cmd extension).
Important: Run the file as an administrator.
Right-click → Run as administrator
This CMD file sets specific registry keys that bypass the hardware checks during setup.
Mount/open the downloaded Windows 11 ISO.
Launch setup.exe.
Click through the setup.
Important: Choose Keep personal files and apps to preserve your data.
After the restart, your system should be updated to the latest Windows 11 version even without TPM.
Verify the version with the command:
winver
Just type it into the Start menu and run it.
Some users encountered the following issue: during the upgrade process, Windows wanted to install updates. If you select this option, the upgrade freezes and won’t complete.
Solution: Uncheck that option.
Note: This option doesn’t appear for everyone.
If you still have problems, you can create a bootable USB stick. With this you can also bypass the Windows 11 requirements. Here’s a brief outline for creating the stick:
After you click Start, you can tick the checkbox to remove all requirements.
Important: If you boot from this stick and proceed through the setup there, everything will be erased.
If you’re unsure, feel free to request a consultation.
Windows 11 officially requires TPM 2.0—but with a simple registry hack via the InPlace_fix.cmd file, you can elegantly work around this limitation on virtual machines or older PCs. This way you keep your system current without having to change your existing infrastructure.
