CF31 Windows 11

For fun, ive just chucked Win11 on my CF31J seems to run rather nicely - Windows update filled in most drivers, the rest installed from the win7x64 infs.

Had to modify the Boot.wim to bypass the CPU check on my VL media to use the second gen i5.

Had an issue with DPC Watchdog violation at first, tracked that back to windows update selecting a generic SATA controller - installing the original Intel series 6 drivers seemed to have fixed this.

Sadly while the fingerprint scanner worked with Win10 Hello, Win11 pegs it as not compatible with Hello, I may investigate more, but currently happy that everythign else seems to work.

Of course, this is my toy laptop and the install, while working isnt supported in any way by any vendor! but it certainly shows that old hardware can run Win11 without any issues!

 

ok, so fixed the fingerprint scanner... this requires a WBF driver which can be downloaded from the windows update catalog manually...

extract the cab and update the driver from the extracted inf

 

as for performance, its snappy and belies the fact that this is a ~10 year old machine! cold boot to logon screen is 14 seconds. Login with biometreics and a functioning start button is ~28 seconds from off.
these times are actually as fast as my 1yr old Dell!! granted, when made to work, the CPU will probably show its age.

Ive been using it today for a few hours and I still have 62% battery - the remaining 4h is a bit optimistic, but it is no less power hungry than when Win7 or 10 were installed.

 

Hi Matt, what processor is in your 31? 3340?

 

Hi Stew, I wish! its a 2540M

 

Good to hear that W11 is working so well on an older processor. I'm reluctant to go to 11 since I've gotten 10 exactly the way I want it--classic shell, Winaero, etc. . . Anyway, good to know that my 10 yr old 31 will work if I'm forced into W11. Thanks for providing the info.
