Just curious really, I've run it on my tablets and my 2 x Dual Core Xeon workstation, and I've heard lots of you with much higher spec machines .... ... but whats the oldest / slowest PC you have found it to be usable at? I have an old P4 3.2ghz that I am tempted to install the x86 edition onto just to see how it runs for a laugh.
So far I've tried the 32bit version on an old MSI Wind Netbook with 2GB ram and it runs OK. Better than 7 did. The good thing I can finally use modern apps on it now because they got rid of the 1024*768 requirement. Also tried the 64bit version on an old Dell Optiplex GX620 which has a Pentium D (Dual Core Pentium 4) @ 3GHz with 4GB of ram and an old 160Gb mechanical drive that actually runs really well. I'm actually surprised by how well it runs. I'm only using the Intel integrated graphics too. With a modern PCI-e video card and an SSD it would actually be usable for me.
ach, what a sad question.. i used to have a room full of antiques, from 8086s, through, 80286s, through 8036s, 80486s, etc.. until i moved house, and there was no longer any room for them. now, some are worth dollarz.. but i no longer have them.. i still have some old dual core pentiums lying around, and they can still roam the www, under xp, so long as you not try to reinvent the wheel, and they can attract some virusses very well... so that is their performance, i guess..
Just installed on an old laptop. It has a Celeron M running at 1 GHz and 512MB ram. Win 10 runs absolutely fine - much better than either XP or Win 7. I have this PC stuck in a cupboard where it performs routine non processor intensive tasks. I have disabled all Apps and live tiles so it is not constantly accessing the network. I think. That is the major difference with old operating systems and Win 10. Win 10 definitely performs better but not if you allow it to be constantly 'helping' you keep abreast of non-essentials over the internet.
i like this post, nicmil54, even if i cannot press the thanks button.. but i would still detest to use win 8 and higher on such a machine.. EDIT; because it is highly unlikely that they will work any better than they will on xp or 7.
My antique Dell Latitude D410 NB with Pentinum M 1.86 Ghz and 2GB RAM will not upgrade (Intel 915 chipset unsupported) but it's doing just fine on W7Ultimate) as that's my "sterile" PC to play with. Latitude D630, T7250 chipset, Intel graphics & 4 GB memory is running just fine on W10Pro 64 bit, ditto the same for Optiplex 380, also C2D E5300 2.6 Ghz with 4GB is running W10Pro 32 bits and also fine. Have a Optiplex D620 MT, P4 chip with 4GB, triple boot to Linux, Vista & W7 - function as server with 3 HDD - doing fine now and I don't think I want to mess with W10 for now, maybe I will change my mind in month #10 - poor thing has been in service for 8 to 10 years now, new power supply not too long ago. After dinner project (update): add my semi-retired Latitude D620 (T2300 CPU @ 1.67 Ghz) to the successful W10Pro (32 bits, of course) activation roster, 2 GB memory with 350G HDD (3 partitions) - took just about an hour from start to finish, a little extra time to tweak those non-Express and privacy/sharing settings, etc. (not about to auto-share/enable WiFi/hotspot, etc.) Everything looking good, can't quite tell whether it's slower or sluggish compared to W7 before. Not bad to have a spare laptop.
How many GB of free space do you need for Windows 10? I have an old Acer netbook, but it's only got like 15 GB spread over 2 drives.
I am try to run it on Lenovo Q190 HTPC Intel Atom 2550 and it work just the same like windows 8.1.Maybe a bit faster.
Old IBM ThinkPad with Intel(R) Pentium(R) M processor 1.86GHz, 2GB RAM and <40GB drive. Works fine but with the Microsoft Basic Display Adapter. That machine originally came with XP.
The downloaded file is under 5 GB (MS said 3.x GB, but the ~BT folder on both laptop & desktop were bigger than that. Then, you need space for the installation & to store the old OS. You probably have just enough space for everything, move some of the data/docs/pix, etc. to USB/external for now, and then hit that Upgrade/Install button. If you install from USB - possibly less space but I haven't done that route, yet.
