The Recovery (D:) drive on your computer is a partitioned hard drive done by your computer manufacturer to allow you to simple restore your computer to its factory settings as it came when your first received your computer.
You should not touch, or alter any files or folders in this partition as it may corrupt the files making it impossible to factory reset your computer. If you do corrupt the files, you may also void your warranty.
I need more space, can I delete the files?
No! You may burn the files to a disk for backup just in case, but you should never delete or rename any of these files. If you do, and you want to restore your computer to the factory default settings, you may get an error, and would have to re-install your Operating System manually.
My computer doesn’t work. Now what?
It’s time for a factory reset. A factory reset is much easier and quicker than re-installing windows because you do not have to install the additional drivers a Windows Installer won’t do.
If you call your computer’s manufacturer’s customer support line for help on why your computer is not working, they will probably tell you to do a factory reset. If that does not fix the problem, you may want to consult a computer expert or send your computer repair shop to get repaired.
