Welcome to the forum.

A low value for "Free" memory is a good thing, zero being the optimum. The value you need to look at is "Available" and that is 1421 MB. While 64% usage on a 4 GB system may be somewhat high there are numerous legitimate reasons why this may be so. 64% usage on a 4 GB system is not going to be causing performance problems. It does not seem likely that your problem is memory related.

Ok i got it. But why i feel lag? In fresh windows? :?

Is your PC's inside (fans/heatsinks) clean? Download HWInfo and run with sensors to check temperatures (CPU/GPU/Motherboard).

Set a High performance power plan - (Control panel - Power options - select High performance - and click "change plan settings" - change advanced power settings - see "Processor power management section" and set them to 100% if not)

Activate Windows then see if that helps!

And might wan to get SP1 and the rest of the updates

Fans is clear, changed thermo, registered windows, updated to sp1, still feeling lag. :/

if you only have 400MB of memory than your pc doesnt meet the system requirements

4000mb
