If i restore my insp. 2200 to factory settings

Your computer gonna be reformatted like it was when it was new. you get a new installed computer. all programs that you have installed gonna be gone. your computer gonna be as new.
if you run restore remember to save your data to a external media as usb disk or networkdevice because all information you have on your computer gonna get lost.
Also you need to reinstall all programs like office, firefox skype or other program you want installed.
The advantages with restore is that you computer becomes as it was when you bought it = faster then today.. remember to install all windows updates before you begins to install any other programs.
Hope I maid it clear for you what happends :) Good luck..
