I guess I misspoke (mistyped?). My "irreplaceable" work product (mostly Office docs and .pst files) has been backed up. The point of my post is that I was hoping to avoid the hassle of having to reset everything from scratch, including things like the constituents of Office program toolbars, preferred file locations, my network locations, etc. All of which I'd have to do in addition to downloading the latest version of software and installing it.
