Ever since I installed windows 10 on my machine, I noticed a huge ram usage even when idle, around 50-60%, so I finally decided to solve the problem.I installed rammap and checked it out, and I saw that I had almost 3gb of ram driver locked.I then used the assessement console to run a memory footprint, and guess what, I found that Fastboot.sys took a whooping 2.7 gb of ram.
Problem is now, how do I solve this?Thanks in advance.

fastboot.sysis a driver provided by Lenovo. So just uninstall all their crapware I guess? – Daniel B Nov 20 '17 at 17:16
