PC lags when moving mouse

[dipsi741]

Hi all, I need help. I have a laptop. My problem is, everytime I move my mouse, my pc lags. When my mouse is not moving, it's all good. It's really annoying because everytime I play a game, it lags like hell. CPU usage is 100%. In task manager it says that windows explorer is causing that. My cpu usage is 100% ONLY when moving my mouse. Using a touchpad is fine. It doesn't lag. Now why is that happening? A few days ago I used the same mouse and it didn't lag... I tried reinstalling drivers but nothing... I also used their official drivers (mouse drivers) but nothing..

My laptop is Dell Inspiron 5567 and my mouse is CND-SGM5N. I am using Windows 10.

Do you have another mouse you can use? This is to rule out the mouse (CND-SGM5N) as the problem.

Not really, but I will buy one in a few days. I'll post here when I try it out. Also I found out that shcore.dll is using the cpu.

So I bough a new mouse and the problem was solved. I dunno why was that happening

Update: It's still happening! But there is less lag in games than it was with the other mouse.

Another update: Making a new user account, or moving desktop icons to another folder solves it, any solutions?
