that's what i can think of off the top of my head at work im sure theres alot more lol

again in no particular order.

1. ObjectDock Plus　　　(7)   Docking Program, makes it easier to access your frequently used progs slightly buggy hence not a 10/10
2. KIS 2010　　　　（9）Cool security software, haven't found anything on my system with any other malware scanner since I started using this, keeps my pc clean.  Full scan can be demanding so run overnight, but otherwise very light on resources. Run in safe mode is excellent, like sandbox.  Vulnerability scan is very useful.  Was going free with rebates earlier this year. 
3. Mailwasher　　　（8）Sits in the tray, pulls your email headers down from server so you can delete spam without opening Outlook
4. Firefox　           (10)  Coolest bit of software, add-ons make this a necessity.
5. BackUpFox       (8, would be 10 if it was automated)  Backs up your profile etc, hasn't been updated in years but still works.
6. WinRar             (8)  For all your zip, rar etc files
7. Directory Opus (8)  File Manager for Windows.  Far better but less pretty than Windows Explorer.
8. CrapCleaner    (10 since I found you can customise it)  eh, clean out the crap off your system.
9. EasyBCD          (10 saved me from mistakes when I started multi booting)  Manage/ edit your multiboot systems. Invaluable.  
10. iReboot            (10)  Pick the OS you want to reboot to.  Simple and very effective, from the makers of EasyBCD.
11. NewsBin Pro       (8 would be 10 if it had a live search rather than having to press enter to search)  For all your newsgroup needs, compact view is the one reason I bought this. 
12. VLC                  (8)To play any video files. 

These are usually amongst the first installed when I set up a new windows OS.
