Slightly OT, erfjr... but there is a little secret regarding Windows "reinstallations.
It's called a non detructive installation, and you can read about it here:
If you already knew about that, please forgive. If not, save that bookmark somewhere. Just rmember, you have to remove SP1 to do it, unless your installation disk from MS is a W7 SP1 disk.
It might save you time and effort.
Also, after you get everything the way you want it, and smart defrag, cleaning your registry and compacting it.... clone your disk on an external HDD.
Will make restoring a breeze in the future.... and keep everything (including your Fences) just the way they were.
