If your machine can deal with Vista it can deal with Windows 8 or Windows 10. You have to disable some knobs like Cortana but usually it&#x27;s not slower. I&#x27;m having a Pentium M notebook with 2GB memory and it&#x27;s working fine. Getting 2GB memory for old machines is pretty cheap - a few dollars on eBay.<p>A desktop with at least some 64bit Core2Duo is actually pretty fast if not even faster with Windows 10 instead of Windows 7 &#x2F; Vista - 4GB is fine for office on such a machine.<p>The only caveat are these privacy and spy addons. I&#x27;ve yet to read some conclusive summary of these.
