Can You Run Windows 11 on Unsupported Hardware?

Yes. Although Microsoft officially requires TPM 2.0, Secure Boot, and an 8th-Gen Intel or Ryzen 2000 processor, millions of computers with older hardware run Windows 11 smoothly without performance degradation.

Method 1: Create a Bypass USB with Rufus (Recommended)

1. Download the official Windows 11 ISO from Microsoft's website.
2. Download the free, open-source tool Rufus (version 4.0 or higher).
3. Insert a USB flash drive (8GB or larger) and open Rufus.
4. Select your Windows 11 ISO file.
5. When you click START, Rufus displays a customization modal. Check the box:
   ☑️ Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0
6. Boot your PC from the USB and install Windows 11 normally. The setup wizard will skip hardware verification.
