A couple things

it may be possible to drag and drop it somewhere but I doubt it. System restore is a system file. So I say you may have a virus that has hidden all your main file. so hit the windows key (hold) press e and release, Explorer opens on top left of window should see organize click find folder options go to view and click on restore defaults, then reset folder options. make sure it applies to all files and folders. Then see if you can find restore. If so right click on it and make sure read only is not blue. It should be empty. You can also press Windows Key(hold) press F. Then type a search for recovery which the exe is in system32 folder. The recovery is stored in system volume information also make sure that is not hidden or set to read only as well...
