[citation][nom]demonhorde665[/nom]i neer do "upgrade" versions , always get a new os , not looking forward to any kind of upgrade at teh moemnt thiough , 1. would have to back up EVERY thing school related (3ds , max files jepgs , of art work , flash presentations, adobe premiere presentations this alone would eat up teh better part of my day 2. would ahve to back up game saves (less time than the otehr stuff but still a hassle 3. would avhe to reformat HD , (and ntot eh quick reformat , not when i do a enw install) 4. install new os , can gbe long process in it's self5. last but not least the killer - reinstall every peice of school software (3ds max , photoshop , illustrator , ms office aps , adobe priemere, maya , adobe acrobat pro., ect ect) then reinstall every game i was playing prior to the new os , as wlel as re d/l any custom content for said games ...this step woudl liekly be a 2-3 day thing with me installing shita round the clock[/citation]
Backup the whole USERS and PROGRAM DATA (or if your using ancient windows xp - DOCUMENTS AND SETTINGS) folders to somewhere safe, wipe the system and install fresh - how hard is that? and when you need the software you simple REINSTALL it when needed - i do the same thing between all the pcs im on - need firefox? reinstall it etc - NOT hard.
Its not difficult - your list there would take me well under 2 hours and the benifits - a much cleaner fresher system, more free space, no errors, no issues at all.
If the down time is that bad and that important you should have a decent backup system in place, and even the i would suggest copying all your required items to the backup so when needed you can install it from the backup - i do all my stuff over the network, i copied the office cd contents to my server and install it directly - installs as if it was from a cd but 10x quicker - most other software allows it too.
Also look into microsofts own software and settings transfer wizard (http://en.wikipedia.org/wiki/Windows_Easy_Transfer) - been around for ages but never touched it my self.
