Steam Client Bootstrapper Not Working ~ Windows 10

Interestingly enough I had this fixed for a couple weeks by deleting everything from my steam install directory except the steam apps folder and the steam.exe file. This no longer has any effect on Steam. Yesterday I came home to it connecting to my account
then never opening the application itself. sometimes it doesn't even get that far. then I have to go into the task manager and kill the steam client bootstrapper (32 bit) along with several background processes it is running. (steam client service (32 bit)
and steam client webhelper (32 bit)). Is this a steam or windows problem? How do I fix it either way?

Windows 10 High CPU usage Fix

Hi i'm writing here to post an answer to the Windows 10 High CPU issue that i found and also ask the Microsoft Team why does this occur so i can understand it.

So to the answer; my CPU usage all of the sudden became high over the last few weeks, i'd tried to trouble shoot as others and Microsoft had suggested, though nothing worked. Microsoft has suggested to create a new account and transfer files which also proved
fruitless after transferring files as explorer.exe again consumed high CPU usage. It was just luck that i stumbled across the solution in one of these threads that linked to an answer from 2011.

Firstly i just want to state that i did download process explorer and it had revealed it was explorer.exe causing high CPU usage and not a .dll file.

The solution:

Broken icons on desktop. That's it. After reading The Solution i found i had 3 desktop files with no
icons at all. I deleted these three files (two shortcuts, one PDF) and instantly the CPU usage by explorer.exe dropped from a constant 38-40% down to 0.2%

I was wondering if someone or Microsoft might be able to clarify what causes this to actually happen?

Thank you
