I also downloaded Windows 11 but put the installation on pause for a later date. After I thought about it a few days I decided to try to do a system recovery. I went into the Control Panel, opened system restore and chose a recovery date three weeks prior to my downloading Windows 11. I hit OK and held my breath. It took my computer an hour to recover but IT WORK!!!!!! No more Windows 11. To check and make sure Windows 11 was gone, I brought up "Windows Update". Windows Update asked me if I wanted to download and install Windows 11 or stay on Windows 10 for now. I choose Windows 10 and that was it. Windows 11 download all gone. The only thing I had to do was make sure my updates for Windows 10 were current since I had backdated my computer. All I can say is that it worked for me. Good Luck
