I suppose it&#x27;s anecdotal, but I had a desktop machine with 4GB of ram that was bought for Windows XP. It dealt well with Windows 7, but the moment I upgraded to Windows 8 I noticed it was very slow. Unwilling to spend time tweaking it, I downgraded immediately.<p>Now I&#x27;m a developer.<p>My mother on the other hand kept a Windows XP laptop running on a Celeron M processor and 1GB of memory. It felt snappy enough; but I wouldn&#x27;t trust it to run Windows 10 applications because while Windows itself might dial down enough, something like Chrome will happily gobble 500GB of memory because it thinks it can.
