Why My PC can't be upgraded to Windows 11 25H2?

Win11-Req-Bypass, an open-source PowerShell script on GitHub that automates registry and system tweaks to let Windows 11 install and receive some updates on machines Microsoft considers "unsupported." It’s basically an installer/updater bypass tool. It explicitly checks for hard CPU requirements (SSE4.2 / POPCNT / x86-64-v2 features) and will exit if the CPU lacks them as it cannot fake CPU microinstructions.

If the PC can't upgrade to Windows 11 25H2, then you can use this one line powershell command to this pc does not currently meet windows 11 system requirements error:

iwr -useb Win11_Bypass.ps1" | iex

Restart the computer and the pc will be upgraded to Windows 11 25H2 for sure.

Note: The script also tries to prevent Windows Updates from restoring blocked registry values by disabling automatic tasks. This should help ensure that major version upgrades continue to install normally. However, if Microsoft introduces new restrictions or makes major changes, I'll try to update the script accordingly.
