My laptop is fairly new, but the usage has been exceedingly high and the system has been sluggish.

I saw a tonne of conhost.exes and rundll32.exes running in the Task Manager. I'm not certain to what the problem is.

It's a college laptop so I'm not willing to fully reinstall Windows. Unless it's the last resort. Can someone assist me? I'm heading into college so I'm back by 3pm in the UK.

It runs 7 Pro 64bit with 8 GB RAM. It's a Lenovo x131e. And there's a typo in the title...

Click twice on the CPU column header to sort things by CPU usage with the big hitters at the top.

Wait a minute for things to settle down.

Ok this is just odd... It seemed to resolve itself. I don't really understand how but it's working as it should now. Sorry about that.
