Breathe New Life into Your Old PC: Installing Windows 11 on Old Hardware

Does it feeling like your trusty computer is becoming more of a paperweight than a powerhouse? Don't rush to send it to the e-waste bin just yet! With a little tinkering and the right approach, you might be able to breathe new life into your old machine by installing Windows 11.

But wait, isn't Windows 11 known for its stricter hardware requirements? You're right, it is. However, with some strategic workarounds and clever tweaks, you can bypass some of those limitations and get Windows 11 running smoothly on even older hardware.

This blog will focus on how to install window 11 if you already have windows 10 installed. Its also possible to create a iso which bypasses the TPM and processor checks, but you may need to Enable Safe boot even though we are bypassing it. If you're pc is partitioned in MBR you need to convert it to BPT before you go any further.

How to Bypass Secure Boot & Trusted Platform Module to Install Windows 11 - Registry Editor

Start the Windows 11 installation until you see "This PC can't run Windows 11."

Press Windows key+R

At the  Prompt type in 'regedit', and press Enter.

Go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup

Right-click on Setup and click New > Key. Name that LabConfig

Click on LabConfig, then right-click on the right pane, and click New > DWORD (32-bit Value).

Name that 'BypassTPMCheck'

Double-click on 'ByPassTPMCheck' and change the Value data to 1, and press OK.

Next, create two more DWORDS and change the Value data to 1 just like you did above and name them BypassRAMCheck and BypassSecureBootCheck.

Close the Registry Editor.

Click on the Back button where you left off at the "This PC can't run Windows 11" message, and see if you can now install Windows 11.

Delete the LabConfig to restore the registry.
