Explorer Disk Usage Stats Extremely Different
Feb 5, 2016
I'm currently on a PC with a 250GB SSD (Samsung EVO850 M.2). Recently my PC suddenly was out of storage and I wondered why, since I though I still had at least half of the storage free.
So I decided to run WinDirStat to figure out which directories were taking up all the space. As you can see in the screenshot it shows completely different values for the used space by the C drive. For your info, I only have a C drive, no second disk or second partition.

From sometime in October, after an update, there have been periods, sometimes intermittent, sometime persisting for a long time, when Disk usage spikes up to 100%, and makes a lot of things unusable.
I did some researching, and disabled a bunch of stuff, like Windows notifications, Windows search, background intelligent transfer and superfetch, even OneDrive, but even on Windows 10 version 1511, Disk usage spikes to 100%, the offending application / service being anything from System to memory compression to 3rd party applications...
This is becoming extremely irritating, and my video playback or something else stutters a lot when disk usage jumps up, often at chronic levels, then backs down, or stays at that usage for some time.

For some reason iexplore.exe consumes extremely high cpu resources. Only IE and only cpu. I have done a myriad of scans:
Roguekiller
TDSSKiller
ESET
Malwarebytes
Bitdefender
and none indicate a Trojan or rootkit. I have also deactivated most extensions and followed dozens of articles on the net. I know I am supposed to use Edge, but it lacks features that I want and has other limitations that make it cumbersome. Likewise Chrome and other browsers react differently for many of the sites I use.

So up until this morning my Windows 10 desktop has been performing really well. When the machine is idle the CPU use is only in the 1-3% range.
For some reason my idle CPU use is now CONSTANTLY 30-40% (even after a reboot)! Task manager says its "Service Host: Local System (15)". If I expand this process in task manager it lists:
Why is this happening all of a sudden? I have all Windows Updates installed and I run an i7-3770 CPU.
My machine is now slow/sluggish with 30-40% being hogged by these services!
I don't have any Malware installed as I run Malwarebytes Premium and the scan comes back clean. Some goes for a full anti virus scan.

My Windows 10 laptop, which previously had Windows 7 (I upgraded through Windows Update) is now having problems with the file explorer.It all started last night, when I was listening to some music with the windows media player, then it froze, a windows popped up asking me if I wanted to end the process and I said yes. From there, it all went downhill. My File Explorer is now EXTREMELY slow, I open a folder and it takes 1 or 2 minute for a new window to even open. Then it takes like 2 more minutes for the new window to even show things. When it does load i can't even scroll up or down or open another subfolder because it freezes and shows "Not responding" at least 3 time before even doing something.
At first I thought it was a performance Issue, but Steam, Task Manager and even games work perfectly fine. Maybe it's worth to mention that my task manager sometimes displays as if my disk was being completely 100% used, but then it goes back to 98%, then back to 100% again, and after a while it calms down and displays the actual percentage. My HDD is more than half free.
Also, when I first installed Windows 10 I had a BSOD Issue. Managed to solve my issue through dump files provided by the W7F Diagnostic Tool. I am trying to back up my most important files to my external hard disk right now in case I have to reset/format my PC, but since the File Explorer is extremely slow, the estimated copy time is more than a day.
Google Chrome won't open and using the Windows 10 search tool at the bottom left makes File Explorer crash sometimes.

So I just took part in the Windows 10 Insider Preview a couple of days ago, and I have to say, Windows 10 is a great step up from Windows 8, they did an excellent job so far. There's just one problem: File Explorer is extremely hard to use. Not only does the file explorer freeze all the time (even on folders with almost nothing in them), when it does freeze, it goes back to the top of the folder when it unfreezes.
What I mean is that I can be half-way down a 260-count file folder, like this:
Then it will freeze, and after it unfreezes, it goes back to the top of the folder, like so:
Doing simple tasks such as moving, copying, renaming, deleting and even scrolling and clicking causes File Explorer to freeze, sometimes even when it's idle!
And what's weirder is that the glitch doesn't happen when your opening a file for a specific program (say you click 'open' in Word and you get the 'Open' dialog box where you can pick a file).
I posted this over to Windows Feedback too, but I don't think it supports user comments, so I'm posting here to see if there's any fix. If there's any fix for this, let me know. It's been annoying me for a while now.

For some reason whenever I open Task manager it says that 100% of my Disk is used, this can be even if all the processes add up to like 2mb or if avast! is running and using 50mb. It will say 100% Disk Usage either way.I sent my HDD back to DinoPC.com a few months ago and they said nothing was wrong with it.

I am running Windows 10 Pro. Over the last couple of days, for some reason, the OS reports 100% disk usage, even when no application is apparently running. It was quite alright a few days ago, but troublesome over the past 2 days. I had assumed it was running some background task, and would become normal, but the abnormally high disk usage persists even after the machine has been running for half an hour.
In this period, no Windows updates were installed, and only a scheduled checkpoint was created 4 days ago. If I try and restore to the checkpoint during boot, I get an error, saying the PC needs to be repaired. If I try it from the recovery option in Windows 10, it does not shut down for a restart, just keeps on the blank screen saying "Initializing restore". The entire time, according to the indication light, the disk seems busy.
I tried disabling superfetch and background intelligent transfer service, but did not work. The spike in disk usage is not specific to anything, sometimes it is the system, other times the malware service...
I do not wish to reset the laptop, as I had quite a few things installed, but I do not have the installation media for those anymore, and so would not be able to install them again after the reset.I have the installation iso for Windows 10. The laptop is Dell 17R SE 7720. I had upgraded to Windows 10 Pro almost 2 months ago, and it had been running fine.

the fact that in the Task manager Disk usage leaps up to 100%, and stays there for minutes with nothing in the column showing above 0.1MB/s. I have visited many forums and tried many fixes but have not cured the problem. The machine is am HP G62 laptop with an i3 processor and 3GB of RAM, which should cope, shouldn't it? Currently CPU 1%, memory 42%, Disk 100% - trying to install a program.

I upgraded to Windows 10 a few months ago. Immediately I began experiencing very long start times (~5 minutes). I resolved the start time issues by doing a clean install and erasing all programs/files on my PC. After that, the 100% disk usage issues continued. I have disabled Windows tips, disabled SuperFetch & PreFetch, and attempted to monitor exactly what is causing this without success. Looking through solutions, it seems that I have gone through all suggested actions yet the issue persists. My PC can be booted for an hour with only Edge running and yet disk usage continues at 100%. Running on 8.1, I never experienced any slow start times or any slow usage.

For the past week or so I have been having strange stutters and hangs. When it started my RAM was maxing out constantly in task manager. Opening Skype or hitting the windows key would basically completely freeze my computer (this was when I had windows 8.1 a week or so ago). I tried a bunch of things as well as upgrading to windows 10 since I figured it could have been a faulty update or something. After messing around with virtual memory for a while that seemed to fix the ram issue.
Now my disk usage is maxing out constantly at very small usage with the same symptoms of Skype freezing my computer and and windows menus being slow. The things increasing disk usage are all around .1MB/s. I have ran Disk Sentinel as well as defragmenting my hard drive, to no avail. Disk Sentinel says that the drive is 52% (Healthy) so I don't think it is a faulty drive, but it could be. I don't know why these issues are occurring as my computer is pretty beefy, albeit with a rather slow hard drive speed.
These are my computer specs: [URL] ....

This morning my girlfriend woke up and loaded up her PC after an Automatic Windows update last night. She noticed that it was extremely slow and almost unresponsive in some cases.Upon checking the task manager we noticed 100% Disk usage on the Performance Monitor. We've tried a few things suggested in some Windows support threads but nothing seems to be working so far.
Solutions tried so far:
- Disabling Prefetch Resources in Chrome and Allowed Write permissions on Skype (Apparently there was an issue with these clashing?)
- Setting the system Page File manually, this didn't work on manual setting or Automatic.
It's been suggested in some Microsoft support threads that Win10 is too much for older systems and hard drives, any truth in this? We've noticed now that after a short time the Disk usage drops to around 60% and then slowly raises back to 100% again.We attempted to troubleshoot any startup programs so went to the task manager to turn everything off for a startup (msconfig doesnt work on win10 it seems), and suddenly her Disk usage dropped back to 0-3%. Honestly don't know whats going on. Didn't think disabling startup programs would change anything until a restart.Went back to 100% Disk usage after about 4-5mins of 0-3%.

I have had an HP Envy dv6 running Windows 8 for two years, Windows 10 for a week or two. The past two months, my computer has been running so sluggish that it's almost inoperable. Startup time has went from 5-8 minutes to 20, sometimes even 40 minutes. When it does load up to login, it takes an additional 20 minutes for me to even load up task manager.
My disk is constantly running at 100%, despite everything running at 0mb/s consistently. The things that go above that are the system, which will spike to 2.2mb/s, norton/Symantec framework which will hover at 0.2 at most, and a bunch of service host:local services (network) processes. HP support, and a bunch of other system background services also run at 0.1mb/s.
I've done a system reboot, which barely worked. I upgraded to 10, which worked for the first two times turning on, but soon went right back to being unresponsive. I've taken a lot of processes out of startup as well. I was unable to stop indexing services when I was on windows 8, despite running as admin.

So I have recently had my Windows 10 laptop take longer than usual to boot up. When everything finally loads up, I check the disk used and it's always at 95-100% for about ten minutes, even though no particular program/process is running high. I've tried a couple recommended tricks (uncheck tips about Windows, disabled superfetch, turn off cloud-based protection in defender) and nothing as worked thus far. The computer itself is less than a year old, and I have plenty of hard drive space and RAM. I've scanned for disk errors, I've done a disk clean-up - and nothing has worked.

My computer will spike up to 100% disk usage at random, rare times. It always happens upon startup though and it makes my computer go to a snails pace when I'm getting everything launched up. I used Windows 10, I've disabled Superfetch, Windows Defender etc. but it only seemed to make the spikes slightly less frequent. The spikes sometimes stay for an extended amount of time, even as I'm typing this, my Task Manager says disk usage is on 99% and my computer started up about 10 minutes ago.

I'm getting a constant high disk usage without even having anything running. Here's a screenshot of my problem
And well, so far I've tried the ''deactivate 'windows search' and 'superfetch''' and it hasn't really done the trick.
Also I resetted my pc yesterday, as of now I'm running a clean install of Windows 10.
Did the ''turn off notifications from Windows'' and really nothing, I've also defrag quite some times with Defraggler and DiskDefrag and nothing.

I need diagnosing why my system disk is running at 100% without anything actually running.
My Anti Virus is not doing anything, windows update is not doing anything, and my disk is not defraging.
I would have never noticed this happening if it wasn't for long load times and reduced FPS in anything 3D. My mouse and keyboard even are lagging and hanging.
My system disk is at 100% and a constant write speed of 1-2 MB/s and a constant read speed of about 200KB/s.
How to diagnose what is using my disk 100% of the time?

Since I upgraded to Windows 10 from Windows 8.1 (who knows when, within the week of first release) I've had a plethora of issues, and recently I found the source of the problem. My computer spikes to 100% disk usage randomly, even with nothing open and will suspend all applications on the computer. A couple of random things can set it off (sometimes when I open the "Search the web and Windows", open an application, Ctrl+Alt+Del, and ALWAYS when I boot my computer)
I've tried every. single. thing. that I have seen on the internet including but not limited to: superfetch, registry stuff, Unistack thing in task manager, Windows defender, uninstalling programs, defragmenting my 1TB Western Digital HDD even though it says 0% fragmented, cleaning up my HDD, checking if my HDD died which it hasn't, and updating my drivers, stopping all startup programs, disabling unused Windows apps, though nothing has seemed to fix the problem permanently. I also used to get this "Display driver AMD has stopped responding but has recovered" though I edited something in the registry and it doesn't show this anymore but I still experience the same problem. I'm quite fed up with this, and I'm thinking about buying Windows 7 in an attempt to downgrade.

For some reason, my disk, when i open my computer and at some other point, always spikes up to 100% for a few minutes.
This happens when :
at the start, Something called System and compressed memory always make my pc go to 100% disk usage. Later on, there are all those Service Host going up to 100% and something called RzStatsManager
When i open norton or when i download something new it also goes to 100%, each time I open google chrome too and Steam make the disk go to 100% at the start and every time i open it it goes to 20% and the system memory goes to 80%...
All these times, the disk spiked at 100% for a few minutes.
I disabled all my notification, each time i open my PC i disable Windows search and superfetch but it spikes up every time. What can I do?

I have this issue where windows seems to hang/get stuck every 5 to 10 seconds for about 2 seconds, like right now while I am typing. I type the words and about three words types out and then hangs for 2 seconds and the rest I typed while stuck gets lost and I have to backspace and restart again.... Same happens with mouse clicks, sometimes when I click it does not register (I presume it is right in that 2 sec delay sweet spot) but the mouse cursor movement is smooth and does not get stuck.
SO I checked my Task Manager and found that RAM,CPU and Network are all low in the 10% - 20%, but my HDD Runs at like 80% -100% all the time. See Screenshots of Task Manager and Resource monitor. The disk keeps getting used full load every 5 to 10 sec.
I have tried disabling Disk Defragment service in the Task Scheduler and several other tips I found on the net but no luck.

I'm running windows 10 with 8GB of RAM, an Intel i5, an ASRock z77 Extreme 4 mobo, and a Radeon Sapphire 7950 HD. All of the sudden when I boot up my computer it is extremely slow and I found out that my disk usage was 100%. None of the processes in task manager show any usage that would warrant even 5% disk usage.
I looked up some guides and disabled Superfetch and Windows Search in services.msc then restarted my pc. That didn't work even though they are still disabled. I let it sit there for 10 or so minutes and the disk usage went back to normal at <5%. It turns out that if I hit the windows key or press the windows button in the bottom left it won't work and it just makes my disk usage go back up and within 15 seconds it is back to normal.
Why my disk usage is so high on startup and why the windows key won't work/makes me use 100% of my disk?

I upgraded to windows 10 when it came out.. however many months ago it came out.. 3? I was running this "WD Black 3TB Performance Desktop Hard Disk Drive - 7200 RPM SATA 6 Gb/s 64MB Cache 3.5 Inch - WD3003FZEX" (copied directly off amazon) for about a year before that. But soon after upgrading to 10 I've been suffering from huge amounts of disk usage. 100% at just 12mb/s PC takes forever to boot and ages to load/transfer things. I've just lived with it for a while.
Anyway. I was reluctant to start anew on a new HDD. So I bought another of the same model.. asuming it had just pooped out. As it runs pretty hot. Hotter than I'm used to a HDD getting. But this new one runs hot right of the box as well. After cloning my system onto the new one I have the exact same issue. I no longer think its hardware related. Is there any way out of this without starting formatting and starting all over?
I'll mention I ran a fresh install of windows on the new HDD before cloning onto it. Ran fine then. And I dunno if its relevant or not but since this problem began my audio will sometimes cut out for several seconds before popping back on.
