How to clean and defrag windows 8

Can you please explain on what you mean on the term "clean"?

Do you mean:

* Disk cleanup utility?

*Clean re-installation of windows 8, when you do not have a installation CD?

*Wiping hard drive completely and not installing OS?

If it is the first case, follow these steps:

* Open file explorer or "My Computer"

* select the Hard Drive that you wish to do these actions on. 

* right click on the selected Hard Drive. 

* click on properties.

* Go to the tools tab. 

* This tab should show you three options.  It is up to you on which order you would like to preform the actions.  Both actions are listed there.  Defragmentation is the "Optimize" option. 

If it's the later two, I do not think defragment would be necessary as a clean installation of Windows 8 means, removing all user files and programs, and reinstalling Windows.

And I would check to see if there are corrupted System Files.

Each Method/step below progresses to the next if the first does not fix any corrupted files that are found, etc.

And these eightforums.com Tutorials are very detailed for problems resulting from SFC Scan:

"How to Run "SFC /SCANNOW" Command at Boot or in Windows 8 and 8.1"

http://www.eightforums.com/tutorials/3047-sfc-scannow-command-run-windows-8-a.html

Read this Section there in conjunction with the rest of the information they give in above link.

   Note

If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If not, then run the **Dism /Online /Cleanup-Image /RestoreHealth**command to repair any component store corruption, restart the PC afterwards, and try the sfc /scannow command again.

If still not, then try using OPTION ONE above to run the sfc /scannow command at boot

If still not, then you could do a refresh of Windows 8, or run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.

If still not, then you can use the steps in the TIP box in the OPTION THREE section to manually replace the files that SFC could not fix.

Refreshing your PC goes like this:

• The PC boots into Windows RE (RecoveryEnvironment).
• Windows RE scans the hard drive for your data, settings, and apps, and puts them aside (on the same drive).
• Windows RE installs a fresh copy of Windows.
• Windows RE restores the data, settings, and apps it has set aside into the newly installed copy of Windows.
• The PC restarts into the newly installed copy of Windows.

"When you reset your PC, the drive will be completely reset, and all your apps and files will be removed from it. Windows 8 will be reinstalled, and you'll need to change any settings and reinstall any apps that you want to get back after resetting. If you know if any files that you don't want to lose, then you should back those files up before starting the reset"
