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.
