Hi

See the post http://answers.microsoft.com/en-us/windows/forum/windows_8-performance/windows-8-keeps-slows-down-to-100-disk-usage-and/cd787f8d-e7b4-4872-aecb-6f0cd15ad942

Towards the end there are couple of posts by Jeremy on how this can be solved by cloning the HDD and formatting it and recloning. I too have this problem on windows 8 / 8.1 machine since more than one year but have not tried the solution suggested by Jeremy yet. I have tried several other tricks.

At least of couple of persons have confirmed that this works

Hi,

Thank you for posting the question in Microsoft Community! As I understand, you are facing performance issues on the computer**.** I understand that it must be frustrating, but rest assured, we are here to help fix the issue and guide you in the right direction.

Method 1:

I would suggest you to restart the computer in clean boot and check if the issue persists.

Follow these steps to start the computer in clean boot:

Step 1:

a) Press the ‘Windows + R’ key on the keyboard.

b) In the ‘Run’ windows type ’MSCONFIG’ and click ‘Ok’.

c) Click the ‘Boot’ tab and uncheck ‘Safe Boot’ option.

d) On the ‘General’ tab, click to select the option ‘Selective startup’, and then click to clear the option Load startup items check box.

e) On the ‘Services’ tab, click to select the ‘Hide all Microsoft services’ check box, and then click ‘Disable all’.

f) On the ‘Startup’ tab, click ‘Open Task Manager’. In the Task Manager windowunder startup tab, right click on each startup item which are enabled and select ‘Disable’.

g) Click ‘OK’, and then click Restart.


Step 2: Enable half of the servicesa. Follow steps 1a and 1b to start the System Configuration utility.

b. Click the Services tab, and then click to select the Hide all Microsoft services check box.

c. Click to select half of the check boxes in the Service list.

d. Click OK, and then click Restart.


Step 3: Determine whether the problem returnsIf the problem still occurs, repeat step 1 and step 2. In step 2, click to clear half of the check boxes that you originally selected in the Service list.

If the problem does not occur, repeat step 1 and step 2. In step 2, select only half of the remaining check boxes that are cleared in the Service list. Repeat these steps until you have selected all the check boxes.

If only one service is selected in the Service list, and you still experience the problem, the selected service causes the problem. Go to step 6. If no service causes this problem, go to step 4.


Step 4: Enable half of the Startup itemsIf no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat step 1 and step 2 without selecting the Hide all Microsoft services check box in either step.


Step 5: Determine whether the problem returnsIf the problem still occurs, repeat step 1 and step 4. In step 4, click to clear half of the check boxes that you originally selected in the Startup Item list.

If the problem does not occur, repeat step 1 and step 4. In step 4, select only half of the remaining check boxes that are cleared in the Startup Item list. Repeat these steps until you have selected all the check boxes.

If only one startup item is selected in the Startup Item list, and you still experience the problem, the startup item that is selected in the list is the service that is causing the problem. Go to step 6.

If no startup item causes this problem, a Microsoft service most likely causes the problem. To determine which Microsoft service may be causing the problem, repeat step 1 and step 2 without selecting the Hide all Microsoft services check box in either step.


Step 6: Resolve the problemAfter you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved. Or, run the System Configuration utility, and then click to clear the check box for the problem item.


Step 7:

Note: After you have finished troubleshooting, follow these steps to boot to normal startup.

a) Press the ‘Windows + R’ key on the keyboard.

b) In the ‘Run’ windows type ’MSCONFIG’ and click ‘Ok’.

c) On the ‘General’ tab, click the ‘Normal Startup’ option, and then click ‘OK’.

d) When you are prompted to restart the computer, click ‘Restart’.

Method 2:

I would suggest you to refer to the link and check if it helps:

Ways to improve your PC's performance

Improve performance by optimizing your hard drive

Note:

a.     If the drive is being used by another program, or is formatted using a file system other than NTFS, FAT, or FAT32, it can't be optimized.

b.    Network drives can't be optimized.

c.     If a drive isn't appearing in Optimize Drives, it might be because it contains an error. Try to repair the drive first, and then return to Optimize Drives to try again. For more info, see "To repair a drive" at the end of this article.

Method 3:

Perform SFC (System File Checker) and see if it helps.

a. Right Click at the bottom left hand side corner of desktop (on Start screen).

b. Select Command Prompt (Admin).

c. Type “SFC /scannow” and press Enter.

If you are still facing the issue, please reply and we will be glad to help you.

Thanks.

    Hi,

    Is this Disk or CPU?  The reason I ask is that the Taskbar icon displays CPU.

    TaskManager should identify which services are running, and at what percent.

    It is somewhat common for high disk\cpu usage right after an install, at least for awhile....

    Your machine may still be loading Delayed Startup stuff...Windows Media Player Sharing may be one of them...I turned mine off...

    Windows Defender\Antivirus may be doing it's first scan...

    There could be some indexing activity going on.

    .Net Framework has a service that runs for quite awhile after being installed and\or updated...

    Some of these things may run for over an hour.

    I eventually rebooted my machine and just let it set idle for the most of an afternoon one day, so this stuff could get caught up, and no more problems.

    You may have some other problem, but try letting it finish this background stuff, and then see what happens.

    hello,.. please give me the solution to my problem..

    I am using VAIO E15127CN and it came with windows 8 PRO

    The problem is everytime taskmanager shows 100% disk usage without running any programs!!

    It happens everytime and persists for 2-3 minutes...!!

    Unable to play games smoothly, cant play HD videos continuously and multitasking is just nightmare...

    The configuration is very high for windows 8 64bit.

    Tried almost everything like resetting pc and used it for 2 days without installing any other programs to make sure that any other app is responsible for this.

    Windows is Up to date, BIOS and drivers are up to date also.

    tell me what to do??? Help please!!

    Hi,

    You most likely have a process running at start causing this... If you right click on the Taskbar and select TaskManager it will display the process that are running in the background and display their CPU and Disk Usage percent...

    There are a couple of different tabs that display the processes, so play around until you find the correct one... I don't have Win 8 running at the moment to be more specific, and the Win 8 tabs are a bit different than Win 7's.

    You can also use the Startup Tab to disable unneeded processes...
