OP i don't run business online and don't understand the amount of tweaking you've done in windows 7. I would back-up all data in a different drive then make two partitions in the main disk. Since i use pc for basic home usage i install 7 only in a 15 gb partition, all my downloads by default go into the D drive not the main system partition hence even if i have to install 7 10 times a month there is no need to back up data as it is already backed up in D partition. I disable all "my pictures/music/movies/downloads" etc because all these are extensions of system C drive. Almost nothing ever goes in my main C drive. Hope you understand. This backing-up thing is way too simpler than what people think all over the world.
I assume u must be using some business related softwares that might need more space so u can make a 50 GB partition for windows 7 and keep all data in the secondary partition usually D.
PS: Since you use ur pc for business avoid useless tweaks for the sake of making the OS look good. I don't use/install anything that i don't really need atleast once a week.
Use:
ccleaner (to clean crap)
revouninstaller: to uninstall softwares
defraggler: to defrag.
All small sized freewares.
