Windows showing unusual behaviour.

Recently I was notified that I should be updated (1809) and moreover the whole laptop was showing unusual behaviour. I eventually updated and after that the system has been showing unusual behaviour of which are

-The texts dissapear from incons, task manager and all

-Whenever I try to open Chrome , the whole pc freezes to the point where the only option is a Power kill

-Disk usage is 100% with no processes on task manager. There are processes but they dont add upto 100% usage combined.

The only thing I did prior to the update was force remove some bloatware since I wanted smoother experience.

I tried using DISM and tried to upgrade my pc to 1903 with media creation tool but the problem still persists.

Thank you.

PS : I also tried the windows repair method tutorial from this forum.

 

Unusual application address in task manager for sttray64.exe

I am trying to repair my Win 10, that newly became so slow, in Chrome browsing and startup, by limiting unnecessary startup programs.
I found a "Program" program and did some research about it and decided to remove it from my PC.
But it could not be displayed in add/remove program list.
right click options are disabled in task manager.
What I realized is that, the addres of this file is unusual, there is a double coat in the middle of address, not at the end!.




"C:\Program" files\IDT\WDM\sttray64.exe
I checked, the file is not in this folder.

I have an updated Antivirus, firewall running.

in thhe other hand, after my last Win updates, my sound system not working properly, for example volume meter is not folowing keyboard buttons, and headphone jack could not mute pc speakers and I can hear from both of them.

So I need experts help.
