NB: There is an issue with the amount of Memory available to the OS depending on the size of the Video buffer. See the section Missing Memory under the Firmware tab.
I have a number of Windows examples here:
In November 2021 I heard from Andrew who decided to go ahead with a straight forward installation of Windows 10:
I don't know what the 'few issues' Jeff Witty encountered when he came to install Windows 10, but his description of building a custom installation of Windows 10 using NTlite did not appeal to me. I thought I'd just go ahead with a standard installation and see what happened.
Installation
My t610 has just 4GB RAM (2 x 2GB) and the standard 16GB SSD module. I removed the 16GB SSD module and fitted a 60GB Intel 520 SSD into the 2nd SATA port (as others have). I used the Windows media creation tool to download and create a bootable USB drive for Win 10 Pro 64-bit (ver 21H1).
After that it was a matter of booting from the USB drive and just letting the installer do its thing. Windows 10 fully installed with no problems and everything in the Device Manager was good (no yellow ! warnings).
Performance
I've been playing with it a bit now and it's definitely sluggish at times - the CPU does spend a lot of time at 99% when it does its regular Windows updates but that's to be expected with the little 1.65GHz (dual core) CPU it has. I've tested a Virtual Box VM (running XP Mode) and that's OK, too.
Chrome is over-bloated these days and so doing anything with that (e.g. Youtube) is a bit of a struggle.
It can play some movies (under VLC) - H264 format is fine but it struggles to play H265 with all the additional CPU overheads for that.
Overall, I think it's a reasonable result.
I don't know what issues Jeff Witty originally encountered with his installation, but we're two years on from his report so maybe they've been fixed in the intervening years.
