Tried disabling TPM in the bios ?, windows update detects TPM and if you have it disabled it will not offer the win 11 update.
It won't, but it'll still nag me by saying "this PC doesn't meet the requirements of Windows 11" as if I cared. I have a Haswell-based HTPC with no TPM, and it does that every time Windows update opens. Not to mention the constant messages about doing an online account and setting up backup (despite the fact that I disabled both messages multiple times), which is also super annoying.
Windows 10 Pro annoys me with W11 update for a Intel 6200U Processor. Which is not on the Microsoft List of supported processor for Windows 11.
The OS Installation is from the refurbish company. The device should be exactly 1 year old now. My refurbished Lenovo laptop is being repaired for a dead display backlight (RMA - 4 weeks). The backside of the notebook has a nice shiny sticker - certified microsoft refurbisher windows license. (I bought that laptop for the odb2 port for my car)
With every windows update in windows 10 pro you see the banner and other annoyance for windows 11. (on an unsupported plattform)
