How To Fix 100% Disk Usage in Windows 10



Sharing buttons:

hi guys this is dude from ez techs in

this tutorial I'll be demonstrating a

number of ways to fix the problem of

100% disk usage in Windows this problem

has recently become more common among

Windows 10 users some typical signs of

this problem include an obvious slowdown

in the overall performance of your

Windows activities like booting to

desktop mouse movements opening of apps

and windows begin to lag significantly

and sometimes they could become

unresponsive entirely here as you can

see from this laptop after the normal

boot process is taking much longer for

the three icons and other taskbar icons

to show up the second and even more

obvious sign of this problem is that

when you open your task manager click on

more details under the process tab you

should notice your disk utilization

percentage nearing or consistently on

100% as you can see on this laptop

this is accompanied by the bar being in

red now even if yours is not stock 100%

but shows anything above 95%

consistently for 5 to 10 minutes after

you boot up then something is definitely

not as it should be and just in case you

are wondering what the normal percentage

should be it depends on the processes

running on your PC with low disk

demanding processes or nothing really

running it should be nearly zero or less

than 10% it could be a bit more but not

close to hundred percent as you can see

in this case the fed are less common

sign of this problem is an unusually

loud noise from the cooling fan as if

your processor graphics card is on the

extra me use has been here from this

laptop

again this is not very common but you

can also experience that in addition to

one or two of the other signs there are

several possible reasons why you may be

having this problem ranging from

hardware to software issues settings and

processes but in any case the solutions

in this video could help you resolve

this problem if one solution doesn't

work for you simply undo the processes

and move on to the next I will also be

explaining briefly how suggestion could

help me resolve in this issue and now

without further ado let's jump right

into it

[Music]

okay so the first thing to try is to

disable your Windows search service now

this might sound a bit weird at first

but here's why the windows search could

be the problem the windows search

service is designed to offer a quick

access to files folders application

settings and just about everything on

your windows which in turn are stored on

your hard drive now to accomplish this

the SAS service is designed to

constantly index all files on your disk

so as to make them readily available

when you search for them from here you

can already understand why this could be

the problem simply put the Search

Indexing could overwhelm your disk

readwrite capacity and keep it at such

high usage state hence slowing down your

windows now by disabling the search

service you will still be able to search

for your apps and other files on the

disk

however it will take a little more time

to show your search results so you can

temporarily disable this X service and

check the impact this has on your system

and then decide whether or not you want

to re-enable it again to disable your

Windows search service press the

keyboard combination control shift

escape or simply search for task manager

from your windows search it always it

should have your task manager pop up

here click on the services tab and then

at the bottom of the page here click on

open services you should have the

services window pop up on this window

search for windows search

right-click on it and select properties

on the properties dialog box where it's

a startup type click on the drop down

and select disabled then apply and hit

OK now restart your computer and see if

the problem has been resolved if you are

still see in the high disk usage on the

task manager then the second thing to

check is your disk defragmentation

configuration now the fragmentation as

you may already know consolidates

fragmented files on your hard drive and

enables efficient and quicker access to

storage locations on the drive however

sometimes this process could get

corrupted by some malware or

applications hence creating an undo

process in the disk and causing such

problem 100% disk usage to rectify this

you will need to stop and disable

scheduled defragmentation from your task

scheduler to do that go to your Windows

search and type task scheduler as shown

on the screen click on tax scheduler

from the search results a window like

this should pop up here click on the

arrow next to task scheduler library to

expand the folder then click to further

expand the Microsoft folder then the

windows folder under the windows folder

locate the folder named defrag and click

on it now you will see an item in this

window named scheduled defrock if yours

is not showing fully you can double

click on this boundary to fully display

it now once you click on this item you

should have a list of the actions you

can perform on it to the right here look

for where it says end and click on it

then asks if you want to end all

instances of this task here hit yes now

come back to this action pane and click

on disable to stop the process from

resuming again when you restart your

computer now immediately you do that

your status here should say disabled

then restart your computer and see if

this has fixed the problem

if not then undo the process by simply

going back and changing the settings to

what they used to be and then proceed

with an exhalation here will be of this

in our device drivers now this is more

likely to solve the problem if you

notice this issue just after installing

a fresh copy of Windows in that case

chances are that after installing your

drivers windows would be able to resolve

this problem automatically one way to do

this would be to run a regular Windows

Update to do that go to your Windows

Start and click on the gear icon to open

your settings on the settings page click

on update and security then on the

window that follows click on check for

updates and wait for the of this

download and install if this is your

first time running on update then it

might prompt you to accept the

installation of the updates after

downloading if you see that just select

accept and install it might also prompt

you to restart your PC to complete the

process

now after running the regular updates

check your device manager to see if all

important drivers uninstalled

if not then you can try to right-click

on each one of the drivers and select

update driver from the options then on

this window select search automatically

for updated driver software because you

will need an internet connection to

complete this process if that fails then

you might need to search online for the

corresponding drivers download and

install accordingly

after installing the required drivers

restart your computer and see if the

problem has been resolved if that still

doesn't fix a problem the next thing to

try would be to disable super fetch

service

superfish is a bug round windows feature

that constantly monitors memory usage

patterns and observes what apps you run

most often hidden marks such apps as

frequently used and then preloads them

into the memory ahead of time now just

like windows search service super fetch

could silently be taking up a

substantial amount of the readwrite

capacity of your disk especially if you

run several different applications

frequently on your windows and over time

this could be contributing to the

problem of this hundred percent disk

usage and slowing down your windows as

you can also see from the task manager

here super fetch is one of the services

that keeps coming up as this laptop

suffers from this height disk usage

problem this might not necessarily be

the issue in your case but it's what

checking to see if this Eblen it would

resolve the problem now just like the

search service by disabling super fetch

you will still be able to launch your

apps as usual however it may take a

little more time to open up to disable

super fetch go to your Windows search

and type CMD right click on command

prompt up from the search result and

select run as administrator on the

command prompt terminal type in the

command n 8 e dot exp space stop space

super fetch as shown on the screen and

hit enter now if you see super fetch

service is stopping and then super fast

service was stopped successfully now

wait for a few minutes and check if this

resolved the high disk usage issue

if it helps then you can permanently

disable super fetch until you choose to

turn it back on to do that go to your

task manager using ctrl shift escape

then on the task manager click on the

services tab and then click on open

services at the bottom of the window now

on the services page search for super

fetch right click on it and select

properties on the properties dialog box

where it says that of type click on the

drop down and select disabled then apply

and hit OK to complete the process

now restart your PC and check and see if

this problem has been resolved if the

still doesn't fix the issue then the

next thing would be to try resetting

your virtual memory that your memory is

basically some kind of memory management

technique that extends your arm

virtually into your hard disk with the

goal of improving performance however

sometimes this technique could be

generating a substantial amount of

read/write requests on the hard disk

hence it could lead to high disk usage

to reset your virtual memory go to your

windows search and type control panel

click on control panel from the search

results on the control panel window

where it says view by click on the

drop-down and select large icons then

locate the system icon and click on it

here click on advanced system settings

the systems properties dialog box should

pop up on the Advanced tab click on

settings under performance the

performance options dialog box should

pop up here click on the Advanced tab

once again and then under the virtual

memory click on change then below the

virtual memory window you will see your

minimum allowed recommended and

currently allocated virtual memory sizes

here as you can see my currently

allocated memory is much larger than the

recommended size which should not

necessarily be a problem but in the case

of high disk usage then you might want

to set this back to the recommended size

to do that first uncheck this

automatically manage paging file size

for all drivers then select custom size

on the initial size field put in the

recommended size

[Music]

then on the maximum size field put in

1.5 times the size of your physical RAM

in MB here - 8 gigabyte so for a 4

gigabyte ram it will be 4 x 1024 1024

the number of em being one gigabyte then

time is 1.5 which will give you 6 1 4 4

MB for 8 gigabyte RAM in the same ven it

will be 1 2 2 8 8 MB so here I will type

in 1 - 2 8 8 now you need to type in

what corresponds to your RAM size then

click on the set button to the right and

hit OK

it then informs me that I have to

restart before this change will take

effect

he hit OK then apply ok and ok again now

ensure you've saved your work and then

hit restart now to complete the process

now if the problem persists after

restarting the next solution would be to

check the configuration of your HCI PCIe

especially if you are using an SSD the

AHCI is short for advanced host

controller interface is a technical

standard that defines the operation of

your SATA host controller this hose

control is what connects your computer

to the hard disk now without getting too

deep into the technicalities of the

processes involved there are times when

your disk would not respond properly to

the input-output request when the so

called message signaled interrupts as

MSI mode is enabled

hence leading to such high disk usage

problem this could be due to firmware

box or some issues with the inbox a HCI

driver called store in HCI dot s why is

that the system driver to resolve this

issue you first need to check to see if

you are running the inbox a HCI driver

to do that go to your windows search and

type device manager click on device

manager from the search results on the

device manager search for the ide 80s

slash atapi controllers click on the

arrow next to it to expand the options

he should have the standard SATA HDI

controller right click on it and select

properties then click on the driver tab

and here click on driver details here if

you have the store HDI dot sis driver in

the list then you are running the inbox

driver now close this and go back to the

controller properties window

here click on details then on the

properties use the drop down to select

device instance path then should have a

value like this here you should take

note of this value you can copy it out

or take a screenshot I'll just use my

snipping tool to make a quick screenshot

then the next step would be to disable

MSI mode for the controller in the

registry to do that go to your search

and type registry click on registry

editor from the search results on the

registry editor carefully navigate to

the following folder beginning with H

key local machines then system then

currentcontrolset ennum PCI and then

look at your HC controller does the

value you copied out in my case I have

the screenshot here

then device parameters interrupt

management message signaled interrupts

properties then double-click on the msi

support key and change the value data

from 1 to 0 hit ok and close the

registry now restart your computer and

see if the problem has been resolved if

not then the next suggestion would be to

disable automatic Windows Update again

this should not normally cause this

problem or sometimes due to malware or

some other sort of malfunctioning your

windows of this service could run into a

loop that could be taken off huge

portion of the readwrite capacity of

your disk and slid into such problem as

100% disk usage in that case you can try

to disable automatic Windows Update

service to see if this fixes the problem

I have demonstrated how to do this in

this recent video I will leave the link

down in the video description section

now if none of these suggestions has

worked for you then you might consider

backing up your files and reinstall in

Windows if you said to do that then you

can check the procedures I showed in

this video on how to backup your files

before installing a fresh copy of

Windows hope one of this was able to

help you out if so drop us a feedback in

the comments section which of the

suggestions worked for you and if you

come across some other working solutions

out there that hasn't been covered in

this video please post in the comments
