> I updated to Windows 10 and found it to be so painfully slow

I initially had that problem, but it seemed to be the fact that (on top of some phoning-home options that I missed disabling originally, which seemed to play some role in the slowness -- disabling them helped) the Windows 10 update from Windows 8.1 also, for some unknown reason, rolled WLAN drivers back to the versions that were several years old (pre-Win8.1 at least) and fairly broken and couldn't automatically locate new ones; redownloading the latest (for Win8.1 -- no Win 10 specific drivers were available for the hardware in question) drivers (which is what had been installed prior to the update) resolved the slowness problems.
