What is Factory Recovery?
Restoring everything like it was a new computer. Everything is cleaned out - just like when you bought it.
On many systems less than 6 or so years old, it is possible to do a Full System Recovery with a few key strokes. In others, this requires Recovery CD's, which came with your computer, [or are available from the manufacturer].
The ROI of a full system restore
The effects of a full system restore on PC speed are the most dramatic, but there is a cost.
The process can take hours to complete, and require backing up personal files and re-installing software.
And, if your computer has too little Memory (RAM) or your fans are full of dust for example, the fix will be short lived.
