I wouldn’t be so sure, Windows is famously annoying to goof with the boot loader on from a running install. You usually need to boot from another system to fix/reinstall it (at least, you did last time I needed to bring back the Windows bootloader on a borked dual boot). Although, since UWP doesn’t work it’s a moot point, that means you probably can’t run Windows Update.
