Windows 10 on Dell Optiplex 755?

[bistwo]

I have an old Dell Optiplex 755 which runs Window 10 quite well. I know that Dell does not officially support Windows 10 on this system, but has anyone had any luck?

dell likely just doesnt have windows 10 drivers for this machine.but windows will find drivers that work so it should be no problem.im running it on older hardware than that with no problems.it actually runs a little better than 7 did.

I just upgraded to Windows 10 pro 64 bit (from Windows 7 pro 64 bit) on 12/23/2015 without any noticeable issues (other than there are a lot of things about W7 I like better than 10) on a Dell Opti-plex 755. I had upgraded the BIOS (A22) and graphics chipset (Q35) to latest before upgrading to Windows 10.

Intel Q35 Chipset
Intel Core 2 Duo E4500 2.2Ghz
8GB DDR2 Ram (4x 2GB)
1x 250GB WD blue
on-board graphics
pci DVI graphics board (presently not used)
no sound card (haven't tested onboard audio, and the Dell system tests didn't find it before upgrading to W10 anyway)

EDIT 12/22/2016: still working great without issue, plugged one of those little 808 sound cans into it and the audio is excellent. BTW the 3.5 internal floppy drive works too although Dell said it didn't provide W10 drivers for it and the W10 pre-test said it wouldn't work last year when upgraded.
