How to reduce ram usage on old laptop?

use ggos iso

I'd probably just whack Linux on that laptop instead of trying to jank fit Windows onto it, which will be slow anyway. 

Go to Control Panel > Programs > Turn Windows features on or off. Disable things you don’t need, like Windows Media Player, Windows Defender (if you rely on a third-party AV), or other optional features.

Looks okay to me. Are you experience lags on the system?

Additionally, if possible, try to upgrade RAM.
