CCleaner says I still have Windows 10 after upgrading to Windows 11

After thinking about it, I remembered what sfc (System File Checker) is. Ah, the fun old days of early Windows versions and AOL hosing your PC. It’s been a long time since I used that! Anyhow, ran it and dism , sfc first like you said. Neither one found any issues. Also let the Windows Update do it’s thing today. rebooted and ran disck cleanup and CCleaner. CCleaner still says I have Windows 10 in the bottom left corner. Funny thing is, my mom has the same exact PC model. HP Pavilion Desktop 590-p0054. I did her upgrade to Windows 11 exactly like I did mine. Hers says she has Windows 11. Go figure. When I go to Windows Settings>System>About it says Windows 11 Home.
