Ever since I bought this laptop, the Inspiron 5515 (I bought two, one for myself, and one for my wife), Windows Update has reported that this system meets the requirments for an upgrade to Windows 11.  I have done the upgrade a couple of times, but have reverted back to Windows 10 (currently Windows 10 Home), because the upgrade didn't resolve the BSOD errors referenced in the following message thread:

However, enough time has passed that I'm thinking about trying the upgrade to Windows 11 again.  Now, Windows Update reports that my system *does* *not* meet the requirments for Windows 11!  Yet, the PC Health Check app, and other apps I've tried, all report that it does in fact meet the requirements for Windows 11.

On a related note, my wife's indentical Inspiron 5515 laptop, is regularly getting the obnoxious full screen ads from Microsoft trying to browbeat her into upgrading to Windows 11.  Multiple steps and clicks to decline the upgrade, only to have to go through it again the next time her system downloads updates from Windows Update.

Anyway, does anyone have any ideas why a system that regularly "passed inspection" from Microsoft's Windows Update for a potential upgrade to Windows 11, would suddenly not pass inspection?  I tell you, the issues I've been having with these Dell laptops along with the issues with Microsoft Windows, has me looking with some curiousity at the Mac world.  That's almost heretical in thinking.  I've been around since the CP/M days.
