my laptop is running to slow and cannot def-rag it i would like to reboot it back to factory settings but do not know how to
"reboot" just means to restart - you mean restore.
For that we need the make and model number of your computer.If there is a hard disk error this could stop defrag from running.
Type chkdsk /f in the Run box and hit Enter key. This will do
a scan on startup. There is also chkdsk /r which is more thorough so will
take a lot longer.Have you checked for viruses? Try MalwareBytes on it, from here:

Run your AV scans too.Make sure you haven't got too many unwanted background programs running.
There is a free program called CCleaner that can get rid of a lot of unwanted junk:

If you do a factory restore, you will lose all your personal files, Windows Updates, & any programs you've installed. Make sure you have everything backed up before doing anything drastic. "cannot def-rag"
Could it be your HDD is almost full?
