What is Shell Experience Host?

[NoLoMo]

I just connected an old monitor to my laptop and found that my CPU was being pushed to 80%. What was taking up most of the memory and CPU was Windows Shell Experience Host. What is it, I ended it and the CPU dropped back to its normal 3%.

Uhhh... when was the last time you ran an anti-malware program on that machine? (I like Malwarebytes)

The shell experience looks more like a malware.

Its not malware, its part of windows itself, but tends to be a heavy cpu usage item

Do what @Stardar1 suggested. Run some anti-malware.

I have experience with some computer malware. Virus/malware hide themself by masking them as a core system task.

A brief Google search would tell you all that it is in fact part of Windows, and the fix is hilarious.

On windows 10 (and ive done some research into this app) the shell experience host is what shows the start menu

I think you should be fine, but you may as well do an integrity check.

 

Run command prompt as administrator by right clicking it and type "/sfc scannow" (w/o the quotes)

 

Wait for it to finish

 

After doing that you should be fine if it was actually a virus, but I doubt it was.
