Fixing 100% disk usage in Windows 10 with Chrome and Skype running

I have neither Skype, nor Google Chrome on my PC, yet this problem still occurs on my PC.  100% disk usage 100% of the time.  Yet when I look at the Processes tab in Task Manager, the column under Disk will show less than 100% cumulative use from all the processes running.  Yet the top of the tab still says 100% disk use.

Under the Resource Monitor, disk use is being used most by "System," but no where near high enough to account for 100% usage.

Something is using my disk, that isn't showing in any of the places that are supposed to show what is in use, and as far as I can tell I've unhidden everything that can be.

This is on a fresh re-install of windows 10, there are no other programs loaded on my PC after a complete wipe and reinstall, this is something caused by Windows, and nothing else.

Exactly Luka.  Same here. 

This is one of a number of program faults that have existed for many years.  There are no unambiguous solution because they can be caused by any of a number of different system states.  Because of cybersecurity, vendors are forced to patch and update software continually.  The size and complexity of the programs is such that exhaustive testing is not practical.  

You've probably noticed that support fora like this one are full of instances where users report success only to follow-up with a whoops! it's back again post.  

What Microsoft (and every other IT software vendor on the planet) has forgotten, is that the users and user interfaces are a parts of the system.  The way software is designed and remotely maintained, software configuration management does not exist.  The best any of these "crowd-sourced" volunteer operations can do, is tell you what worked in their particular configuration and code base, at the particular state the hardware and software were in at the moment.  (The details of the code changes in are not available to the user for a combination of proprietary and cybersecurity concerns.)  

Sparing the details, one of the things that it appears several hundred thousand of us are struggling with is a recurring inability to access network attached storage.  Some solutions appear to work some of the time or until the next update. (I've been in the digital system design business for about half a century.  I'm not up to following 14 pages of detailed instructions like, "change the XDFG setting in line 341 of the  RRTWQ module to 55t77YHI***h9923llkjlbhh442%!q".  

On the other hand, after 50 years I have a pretty good intuitive sense of the root causes of what I'm seeing.  Yesterday, relying on that instinct I finally got the system to recognize the NAS and display the directory structure with the files, by doing something suggested to solve another problem (the green ribbon of death).  This was a major improvement over the previous two days, when, by rebooting everything I could occasionally get the system to display the drive and the folders but no files.  (Using Properties I was able to determine that I had 208 GBytes of data stored, and a potload of folders with 0 bytes in them.) 

Again, experience cautioned me that it was too soon to celebrate.  I tried to load a file.  The result was simply mindboggling.

A page generated by Microsoft appeared with a prominent banner reading:  "Join the Celebration -- Get the Windows 10 Anniversary Update today!!"  The content of the page informed me "Your App doesn't work with Windows 10,"  and directed me to go to the App developers Website for a solution. 

What App was not specified, and I was clueless, since all I had done was double click on a filename to see if it would load.  

At which point the Windows 10 viewer archly informed me, ""We can't open this file." 

There is no way that an average user can deal with this level of insanity.

I need help nothing here helped me fix this issue usually Windows defender does this to my disk or the system and compressed memory i need help

Ha ha James, I like that last comment, very probably true.

I have managed to solve this for my PC using the following two articles:

1.  https://support.microsoft.com/en-us/kb/3083595

This is medium technical and involves using the registry editor to turn off a parameter for your hard drive controller - something to do with interrupts.

2.  http://www.makeuseof.com/tag/4-tips-fix-100-disk-usage-improve-windows-performance/

Which led me to discover I had some areas of my HDD that needed repairing (following a chkdsk) and I also switched off the 'windows search' and 'superfetch' services.  If I reboot and it comes back, I shall permanently disable 'windows search' and 'superfetch'.

My disk usage slowly started to fall from 100% back to normal 0-5% when idle.

I hope this helps.

I also wonder if Microsoft have kind-of written-off users' HDD issue because newer hardware will be using SSDs instead which are a much better storage solution.  Maybe Windows 10 assumes SSDs will be used and is more geared up for this than for the old HDDs.  I am going to replace my laptop's HDD with and SSD as soon as I can.

Sorry,  I appreciate the effort, but I don't have Chrome, or Skype installed.  My system still consistently stalls because of 100% usage, and when I look at resources in Task Manager, the hogs are my NAS Backup or something Microsoft.  

Honestly, I don't think anyone has a clue what the software does anymore.
