I just finished installing Windows 11 Pro on my Venue 11 Pro 7140 and it works perfectly.

I created a Windows 11 boot USB and did a clean install adding the LabConfig key to the install registry following the procedure described in www.windowsreport.com/install-windows-11-without-tpm

After you boot Windows 11, you need to download and manually install the Windows 10 Realtek HD Audio Codec, Intel 7265 Bluetooth driver and Intel HD4000-5000 Graphics driver for the Venue 11 Pro 7140.

Although Microsoft states that this is an unsupported configuration, I was able to get the latest updates through Windows Update in Settings.
