100% Disk Usage during startup/opening new programs


Hello,
Awhile ago, I was still on Windows 7, and my system began to be incredibly slow, especially during startup. I wasn't sure back then what the problem was, or what I had done to make it so slow. I figured it was linked to BlueStacks, and uninstalling it did help a lot. Startup took about 10 minutes, instead of over 30. However, it was still very slow to open programs, right click, and play games. I thought upgrading to windows 10 might help, but I was unable to because of an error. It only worked after I used CCleaner to fix up the registry. Windows 10 allowed me to see the cause of the sluggish behaviour, as task manager reports 100% disk usage during starup. The problem is, no program in the list actually uses the disk activity, and idles around 0.3MB/sec. It was still always 100%, and only started dropping to normal levels after I messed around with skype (see below for the list of things I tried). Now after startup, if left for a long while, it will eventually finish and drop to idle around 0%. But if I open a program for the first time (ie. WoW, Firefox, Documents, Word etc.) it spikes to 100%. For most programs, it will return to 0%, such as firefox. I am able to browse with no problem, but it will occasionally still spike to 100%, though this seems random. It is most noticable when playing games, such as WoW. If opening for the first time, it spikes to 100%. Some time later it will return to 0%. If I log in, or switch zones when playing, open my bags etc, it again spikes to 100% and makes the game almost unplayable, as it freezes until disk usage returns to 0%. It only behaves this way on lowest settings. If I play on max settings, it almost always stays at 100% (my laptop can easily handle max settings btw). Other games are similar, but the less complex the game is, the less spikes happen. Here is a list of things I have tried to fix the 100% disk usage:
-Turn off tips about windows - no effect
-Turn off BITS - no effect
-Turn of prefetch and superfetch - no effect
-Turned on read/write for skype using the security tab in properties - Disk usage is no longer always 100%, but still spikes as told above.
-Turned off cloud protection and real time protection for windows defender - no effect
-Uninstalled/reinstalled nvidia drivers, and geforce experience - no effect, also worth mentioning that when I restarted after uninstalling, the system took almost an hour to startup, disk usage was again always 100%, and took ages to reinstall the latest drivers. After using CCleaner and getting rid of system files/registry cleanup, the system was as before, 0% disk usage, but 100% spikes.
-Increasing the RAM cache - no effect
-turning off disk fragment scheduling
-Disabling all startup programs - startup takes a lot less time, but disk usage is still 100% during startup
-Disabling all non-microsoft services - no effect
-Check disk using cmd, no errors reported
I installed HD sentinel, and it says disk health is at 98%, with 3 weak sectors, but no action required. Disk temperature is also normal, but if disk usage is 100% for long enough, it begins rising, up to 60+ degrees (C).
Im running out of options, as I've tried nearly everything suggested by google. The only thing that had any significant effect was the read/write enabling for skype, but even that didnt solve the problem entirely. I even tried uninstalling skype, to no avail.
Please help, the new patch for WoW released, and I really want to be able to play normally. Sorry for the lengthy post.

 

100% disk usage when opening ANY program

ýes but that's the thing, any program i open will make it go to 100% so a screenshot wont really make a difference, if i open lets say world of warcraft, it says world of warcraft is using a huge amount of disk, if i open discord, it says discord is using
an insane amount of disk, if i open microsoft edge it says microsoft edge uses an insane amount of disk. its like this for every single program and it doesn't matter how small or big it is. so there's no specific program that does this.

 

How do I stop my disk usage being at 99% or 100% on Windows 10?

How do I stop my disk usage being at 100% on Windows 10? Below is what I've tried

• Changing Link Storage Technology in Intel Rapid Storage to be off
• Restarting or Disabling Windows Search service
• Restarting or Disabling Windows Superfetch or SysMain service
• DISM and SFC scans
• Checking for hard drive errors in CrystalDiskInfo
• Running programs as administrator
• Changing the security of backup programs and high disk usage programs to give my user all the permissions in the Properties
• Looking at Task Manager to find the cause (the processes listed don't add up to 99% or 100%)

I'm using Windows 10 20H2
Is there any other suggestions I can do?
