Posting this just in case -- I doubt anyone uses Windows Backup, since 3rd party backup apps are so much better.
Microsoft included a disk image backup app with Win7, and they've continued to ship the Win7 app with Win8-11. One of the options is to create a rescue disc, CD or DVD, rather than a bootable USB stick. If you did that, and installed a Windows Update on or after Jan. 11, 2022, that disc will not start.
