How can I upgrade or install Windows 11 26H1 on unsupported computer?

Win11-Req-Bypass is a lightweight, script-based method used to bypass Windows 11 hardware requirement checks, including TPM 2.0, Secure Boot, unsupported CPU, RAM, and storage limits during installation.

Unlike GUI tools, it works by injecting registry keys or using an AutoUnattend.xml answer file that tells Windows Setup to ignore compatibility checks. Because it relies on native Windows setup behavior rather than modifying system files, it remains effective even for newer builds like Windows 11 26H1, as long as Microsoft keeps the same setup logic.

How to install Windows 11 26H1 on an unsupported PC

Step 1: Get the official Windows 11 26H1 ISO from Microsoft (Release Preview / Insider, depending on availability).

Step 2: Use any standard tool to create a normal Windows 11 installer.

Step 3: Place a preconfigured AutoUnattend.xml file in the root of the USB drive.

Step 4:  Return to the installer, select your edition, partition the disk, and complete the Windows 11 26H1 installation as usual.

Win11-Req-Bypass is a clean, script-level alternative to Flyby11 that works well for installing Windows 11 26H1 on unsupported PCs. It does not require modified ISOs or third-party patching tools and can be reused across multiple machines. While it lacks a graphical interface, it offers maximum flexibility and remains one of the most future-proof ways to bypass Windows 11 hardware checks.
