Windows 10: My laptop started working slower after defragmentation.

I decided to scan my HDD for fragmented files. The results were.. 50% of the files were fragmented! I used an app called O&O Defrag.

Questions related to defragmentation

Hello Bookum,

Thank you for posting your query in Microsoft Community.

I will help you out with the queries regarding disk defragmentation.

Defragmentation will work even if the computer goes to sleep mode.

However, if you face any issue, you can change the sleep mode time.

Follow the steps below:

• Type "power options" in start menu and select Power options.
• Select "Change plan settings" next to "Balanced".
• Change the time for sleep mode.

And, if you interrupt the defragmentation in between, the defragmentation will start from first when you perform again.

I hope this information helps.

Thank you.

• In the window that opens enter chkdsk /f.
  

Method 2:
Run System File Checker (SFC).

Method 3: Check if Disk Defragmenter service is running properly.

This service is required for performing disk defragmentation, and if it’s disable, you won’t be able to run a defragmentation tool.

• Search for services.msc.
• Make sure that Disk Defragmenter service is set to
  manual.
• Also, make sure that following services are set to Automatic:
  
  Remote Procedure Call (RPC).
  
  DCOM Server Process Launcher.
  
  RPC Endpoint Mapper.
  

Let us know how it goes.
