win 10 help

[#1]

OK my mate called this morning with an issue on his w10 lappy.
He starts explorer using the quick start icon and it takes ~2min to load.
He double clicks on a doc shortcut and it loads immediately.
No network mounted volumes so not that.
Win+E takes same time.
Google on it shows no real answers, I left it doing a sfc check.
Any ideas guys? My knowledge of M$ stops at XP.

it would help if you posted in the windows forum - reported to mods

Opps! force of habit I suppose.

A friend of mine had a similar problem after upgrading. I think IE has problems on some upgrades.
As a quick fix I got her to try the Edge browser as an alternative. That was quick to start up. It was also easy to transfer all her shortcuts. She was happy. I have never found the time to investigate  further.
Try Edge as an alternative.
You might also try clearing the IE cache
Update - Sorry misunderstood the Explorer in question - I would still try clearing any recent files cache.

I think he is using edge, but it is FILE explorer not Internet Explorer.
Browser is fine web pages opening OK. (Bar the fact Bing is carp)

You don't have to use Bing!

[#7]

I don't but it is his default search !
First I noticed when I searched was all the rubbish it came up with.
I have tried to train him with firefox + adblock + google but he keeps going back to ie.

Use DuckDuckGo in place of Google.
