Can confirm. You could also try creating a Windows 11 installation USB and upgrading from that, which sometimes bypasses the issues the in-place upgrade hits.

This. Yeah, that's a solid workaround. One extra tip: if you go the USB route, temporarily disconnect any non-essential peripherals like extra monitors or printers during the install—it can help avoid driver conflicts.

Agreed. Also, before you run the setup from the USB, try disabling any third-party antivirus software temporarily—it can sometimes block the installation.

Same here. You could also try creating a Windows 11 installation USB and doing a clean install instead of the in-place upgrade.
