Windows 10: Unwanted Disk Defragmentation After Windows Update

Thank you Microsoft. After an update to Windows 10 my computer insists on running Defrag after every boot and twice every day. The machine is catatonic because it runs at an insane priority for an hour and a half each time it defrags. You can't run ANYTHING while this goes on. My patience is at an end. Please tell me how to end this insanity for good. I have disabled it in task scheduler but it still runs at boot.Thanks in advance.

Defragmentation not working, and new update causing crashes

Hi,

It is possible that Disk Defragmenter service has been disabled or not properly running on your PC, causing defragmentation issues. To troubleshoot this, kindly try these following methods:

Run System File Checker

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. To do so, follow these steps:

• Right-click the Start Menu and select Command Prompt (Admin).
• Run this command: SFC /scannow
• This may take several minutes to finish. If Command Prompt shows Verification 100% complete, close the command prompt and check if your issue has been fixed.

Check Disk Defragmenter service

Disk Defragmenter service is required to perform disk defragmentation. If Disk Defragmenter service and other services that is required to perform disk defragmentation is disabled, you may encounter issues doing defragmentation. To troubleshoot this, follow

disk defragmentation

Hi,

To defragment your hard disk:

1. Click the Start button. In the search box, type Disk Defragmenter, and then in the list of results, click Disk Defragmenter.

2. Select the disk you want to defragment.

3. Click Analyze disk to determine if the disk needs to be defragmented or not.

4. If fragmentation is above 10%, you should defragment the disk.

5. Click Defragment disk, in order to defragment the disk.

(The above method is based on Disk Defragmenter tool for Windows 8)

Code:

Disk Defragmenter runs but when finished it now shows 14% fragmented.

Hi Jim,

Thank you for posting your query in Microsoft Community.

Provide us with the below details for better clarity on the issue.

• 
  Did you perform the defragmentation internally or on an external drive?
  
• 
  Do you face any performance related issues even after the defragmentation?
  

You can ignore the message if you are not facing any performance related issue
after the process is done. It might be due to some error in the reporting. Then it won’t be an issue to worry about. If that is not the case, and you are still facing performance related issues, I suggest you to try the below steps and check if it
helps.

Step 1: Run a Disc Check on the computer.

You can perform a check disk to spot any error in your hard disk. To do so, right- click on the start button>select command prompt (admin)> type “chkdsk” and press enter.

This will display the exact errors occurring in your hard drive. Restart the computer and try Step 2.

Step 2: Perform a Disk Cleanup on your computer.

Refer the link below for steps to perform a Disk Cleanup.

Now, Run Disk Defragmentation and check if the issue persists.

Hope this information helps and let us know the status of the issue we will be glad to help you further.
