100% Disk Usage in Windows 10 Tips 

I liked that you explained why disabling each service might help instead of just blindly disabling them without explanation. +Sub

I had that problem. I tried everything in the last video. Got rid of my crappy hard drive for ssd. Now it runs beautiful.

Been having Disk Usage problems for some amount of time, and all the other videos don't go into exact detail as to why you need to disable these specific programs you showed. But unlike them, you point it out and you explain enough for those whom aren't tech savy to understand why these services are even there to begin with. Thank you, CPU Tech.

Took my disk usage from 100% down to 8%. Absolutely wonderful. Thank you so much.

You are one of the best tech teachers I have ever seen, not exaggerating. Clean, clear and concise. Thank you so much.

THANK YOU so much - your first tip was missing from EVERY other video I've watched on this. Disabling Superfetch worked at first but the next time i went a week or so without using my laptop it was back at 100% - i did everything short of chkdsk because my settings wouldn't let me run one (?). The Connected user Telemtry function was the new culprit. You are a goddamn hero, my man!

I’ve tried various things for years but your tips actually helped the problem! I was also scared of doing some of the things others suggested because I had no idea what it would do to my computer. Thank you so much.

The best part of this video that others fail at is, explaining what each disabling does. 10/10

Thank you so much for explaining what disabling the services you mentioned does. I really appreciate this. I have an online exam tomorrow morning and the disk usage slows down my laptop's performance dramatically. So this helped a lot.

A fun tip that I always suggest: let you laptop run idle every so often, especially if you rarely use it for long period of time. It lets Windows rearrange items and complete tasks that would otherwise bog down your sporadic usage!

I only today found your site and have already learnt more than I know what to do with. I'm looking forward to checking out your back catalogue. Thank you.

You did an EXCELLENT job with this video. Easy to watch, clearly explaining what you are doing and why. Well done. Fixed my issue with editing the registry regarding that storehci driver.

Wow. You are absolutely amazing! I love the way you explain things (as other comments have also mentioned). I've been looking for a solution to my disk issues for a long while now and only this video has helped so far. Subbing for sure!

In the section about editing the registry (that is the section about the disk controller), the Regedit tool has a SEARCH function - much better than trying to visually match the string with the listing in Regedit. If you click on "Edit" at the top of the Regedit window, one option is Search.

Dude, I watch like 5 other videos before I found yours. Yours was literally the only one that did anything. Thanks

Thank you! This was a great video. You were clear, consice, and easy to follow. The 100% disk useage has been plaguing me and making it difficult to get important work done. Fixing the driver bug was what resolved it for me. I know I need to just give in and buy an SSD but in the meantime this has made life much easier.

You're a lifesaver. Disabling SysMain did the trick for me. Disk usage went from 100% to hovering around 10-15%. Excellent tips that actually works! Thanks man.

IDK how this ended up in my recommendations, but gat damn am i glad it did! Thanks d00d!

I searched so many videos in RU-vid none of them worked. Your tips worked . Thankyou for educating us in tech side

Thank you. I don't know which step help me but one of them did. I've seen some people in these comments say none of these steps help their problem but I'm glad I'm not one of those people. I'm glad to report that all of these tips still work in 2022.

Thanks for awsome video man, I also really liked the last part that the way you spoke so sincerely

From 83-100% to 5% below disk usage. Thank you so much! I'm now a new subscriber

The step involving the IDE Controllers worked for me. Thank you so , so much. You have no idea how relieved I am to finally fix this!

You're an absolute legend. Was about to heave the thing in the bin. Thank you for taking the time to explain everything so clearly. Liked and subbed.

Appreciate your insight into what they actually do and why disabling htem is no big deal. SysMain was the culprit on my computer. I was CONSTANTLY hovering at 100, to the point where the computer was becoming unusable. Disable SysMain and it IMMEDIATELY dropped down to hovering around zero (albeit still bouncing around.) Thanks brother!

I would "apply" the disable prior to stopping the service. some start up right away and will be running even after you disable. Wsearch did this.

Dude. Finally i find someone that provides very complete instructions to help my friends and family with this problem (when MS pushes win10 to old pcs, it is a nightmare). Thank you! Subscribed as well!

Great advice, worked like a charm!! I've been having this issue for some time now and yours was the only solution! Thanks!

By far the best explanation how to fix your pc. My laptop is already super fast from up to an hour waiting to open a darn program. Thank you very much.

This video is great to follow along with and gain understanding. A+ video. I still have high disk usage - however disabling the driver in the last tip solved the hang-up problem that had me wondering why my disk usage was high in the first place. I'll update to an SSD to keep up with the times, but for now this totally solved my problem of browser tabs needing 5-10 minutes to load after re-start.

Wow. Great video, man. It had crossed my mind that my 100% disk usage came down to the OS expecting an SSD to be in use. I mean, it IS becoming the standard now and for good reason. Thanks for the direct and informative tips, brother. Liked and subscribed.

Thanks for this. My wife's computer was constantly showing 100%. That regedit fix did the trick along with disabling sysmain. Thanks again. Thumbs up!

You are a hero. I was on the verge of getting a new computer, but thanks to you there's no need

i just saw this videos while surfing, i have no doubt your previous content on this topic is most viewed

Awesome tips! I have been having trouble with my lenovo laptop and the Sysmain thing did the trick for me . From 95+ disk usage to almost 35% now. Thanks so much!!!

Just the first 2 steps helped out an insane amount, definitely got a new sub👌🏻 awesome job

Don't have any problems with disc usage, but got this vid in recommended and watching just in case 😄

Wicked. First time I've seen my laptop run this far in years and it was easy to follow.

From 100% to 1% disabling Windows search! Very good, I'm thankful!🙏💖

I switched these off last year and now they are back on. Had to go back to this. Great video. Thanks.

Thanks for the help! Have an extra sub on your computer journey, and good luck!

The only reasons you would want a Hard Disk Drive is: 1) To write/read large data "linearly" in the most efficient manner like Audio/Video. 2) For Archiving in general. Hard Disk Drives last a LOT longer than SSDs in use and storage. Nowadays, the OS drive and general data drives should always be a SATA SSD at the very least or a M.2 for best performance for sure.

Useful tips! I discovered your channel last night. I'll be flipping some older systems to win 10 thanks to you. Right now I'm on an older win 10 build - on a netbook that was just given to me. Perfect if I want a larger screen than my phone when travelling. The more resources I can free up on it the better. I might try slimmed win 10 version later on. Thanks and subscribed!

Can't thank you enough, this video was the most useful, informative and easy to follow guide on this issue!

This dude is a legend 🙌🏾💯

The content was impressive. Straight to the point, clear concise explanation on what we doing , and it works too..damn i was late to find this channel. Thanks!

Windows search fixed it straight away, you are amazing!! Liked and subbed ❤

Hey thanks man this fixed my issue with the 100% disk. Much appreciated. I threw a Like and a sub thanks again!

Thank you for the tips :) One thing to avoid the 100% CPU Usage is to make your dedicated graphics card (if you have one) your default card. Works miracles!

great man. great content. subbing cause you deserve the community

You are a genius man, the part about SATA driver fix for me!...I had not seen it in any other video, subscribed!

Thank you this has been really helpful my PC was working at hundred percent disk usage and I was so frustrated about that but thank you your video really helps me a lot and thank you

Great video, I've done a lot of the work you've demonstrated here for helping friend's & family to lower their 100% disc usage, but the regedit one was new to me. Hence, I haven't had 100% success with every time I've encountered the problem. One minor, if I may; regedit, pronounced rej-edit - as in, registry.. not reg as in regular.

This video is the best video I have ever seen, well presented!!!

I found your channel recently and I'm truly glad I did. 😊

Thank you so much for such an informative and helpful video! I've done most of the tips you mentioned in the video (minus the search one) and I'm hoping this will help a lot with my main SSD usage :)

Thank you so much! My computer was crashing all the time and was so slow. I just found out today, that my disk % was at a 100. I disabled the first two on your list, and now it is at about 2% and 59% when I play a relatively heavy game (for my PC at least). And it surely helped with the speed a lot. Looking forward to see if it has helped with the crashing in the long run too (or if I need a new PSU), but it has not crashed since.

In lieu of this being posted again, I mentioned having 100% disk read issues and a whole layer of wacky problems related to kernal issues. Long story short, repairing Windows 10's system files completely fixed the disk usage problem. Whatever it was that was corrupt somehow some way was entirely fixed after repairing the OS. Its pretty ironic actually, that's usually the last resort method I choose after exhausting everything else and even that rarely works. Usually formatting is the end point. Basically, if you've tried everything here I would highly recommend just trying the most obvious thing outside of windows update and that is just using the repair function for the OS.

i never usually comment on videos but this one definitely deserves it!!!! it really helped be out and brought my CPU from 60% down to 4%. keep up the amazing work!!!!!

Thanks for the detailed info. Spinning disks of the 5400 and not even 7200rpm variety sadly still exist in the workplace and we all make due with what we have. Fortunately for you and Chris Titus Tuning Scripts you've made PCs Great Again. 👍

amazing, the way u explain. !!subscribed !!

Just so you know, the all the High Performance plan does is is stop the CPU from idling at a lower clock speed, it does not affect disk usage at all. I would actually recommend leaving it on balanced unless you know that you definitely need it on the High Performance plan. Leaving it on high performance will likely significantly reduce battery life on laptops when just doing basic tasks like browsing the web or watching videos where the CPU is likely barely being used anyway.

I had already looked into this quite a bit and got my disk from crawling at 100% constantly to about 75%. As soon as I stopped the first service (Microsoft malware) you mentioned, it hit 0% and has been staying in the single digits. Thanks, man!

Had the Storaci Issue and never would've gotten the help elsewhere on the internet, thanks a ton!

disabled sysmain and went from 100% to 3% disk usage thats insane

Champion stuff as usual

WATCHED ALL THE RECENT VEDIOS BUT THIS 2 YEAR OLD VID HELPED MY PROBLEM. THANK YOUUUU

Fantastic. This is the first video that really helped me to solve the problem. Thank you so much Sir.

I disabled “Connected user experiences and Telemetry” and my disk went from a constant 100% all the time instantly down to about 15%

Nice find with the driver issue. You could have pasted the path in regedit as opposed to scrolling to find the string by the way 😉

Extremely helpful! Liked, shared, downloaded!

Thank you so much! After so many videos, your tips helped me to take my disk usage from 100% to 4% 😊

The INSTANT I turned off search my disk usage went from 100% to 1%. Thank you!

Disabling Connected User Experiences and Telemetry fixed it instantly for me, wow.

I've just followed the tips accordingly, and it worked for me. My disk usage dropped from 100% to 7%, sometimes it tends to increase but just for a while, however, I can say that the problem was solved. Thanks

when i tell you i was this close to throwing my pc out my window i mean it fr fr thank you brother straight to the point, explaining and fixed the problem and was way more comforting then watching a video with a robot voice talking to me giving some bullshit solution u earned a sub n a like my man

This guy is awesome it lowered my disk usage but im still going to get a ssd because its worth it

You’re a beast bro!! Thanks a lot!

Thank you so much. I was finally able to fix this problem after trying for so long, and your explanations are top notch.

Hey bro you fixed this problem for me with that bug problem that I couldn’t find anyone else with this info. Thanks!

Installed SSD about 3 weeks ago... now i have 1 SSD for Windows and normal HD for other... SSD IS ANOTHER WORLD.... AMAZING FAST.

Beautiful bro,beautiful! This video is the mash-up of all those tips scattered on RU-vid! All in one. But does disabling automatic pagefile monitoring and setting it to manual also help?

Thanks a lot man! You helped me out a lot and also made me feel like I’m a computer genius! 😂 Subscribed 👍🏼

This helped me solve a slow workstation PC. Thanks!

Honestly, the single biggest improvement I found on older Win 10 PC's regarding high disk usage, especially at startup, upgrade to an SSD. Less then $100 and breathes new life into older PC's and laptops. That and bump RAM to 8GB. Those two changes alone help dramatically.

Nicely ,clearly explaining Work 100% Honestly Friendly ways No ad No bull**** No scam Subscribed 👍

Worked like a charm. Outstanding advice! Thanks a lot for the explanation

Omg!... You just saved my career right now.. My system has been distorting like crazy for months now. I basically couldn't do anything on my music production software until I thought to search RU-vid for help. I'm glad I found your video. Right now my CPU peaks at 15% max..... this is a miracle..... Thank you❤.

Thank you Sir, have a great days to you too.

i tried everything but got nothing.

I love your video, man. It resolved my HDD problem. Thank you!

Thanks dude, the SATA thing was the major issue for me and I watched many videos and couldn't get the right way.Very very thanks you fixed my problem ❤

I didn't know sysmain is the old prefetch. It was the main culprit. Stopped it and now disk usage stopped running at 100% on start up and quickly dropped way down. Also stopped the snooping telemetry service. thanks.

Thank you so much... Now I know wtf these services do and not just disable them blindly...

THANK YOU, was struggling after windows 10 update but this video helps me

Thank You so Much sir🙏❤This helped a loooot...am your long time subscriber and your content is always on point!!

Thanks! With 2 of your applications, looks like I gained a gig in ram!

System main was my problem. God Bless you

This is the most helpful video if your trying to make a gaming pc out of an old computer thank you so much

Hi, before I watched your video, I had just about trashed my HP Prodesk-400. To speed up, I even increased RAM to 32GB and HDD to 1TB but to no avail until I followed you instructions in this video. A BIG THANK YOU! Now my PC flies superfast.
