Is there any way so that I can edit something in the registry or something so that every program gets installed automatically into e:/Program Files instead of c:/Program Files. Since my e:/ drive is much bigger (80GB) than my c:/ (40GB), id rather use it for everything. But I also am too lazy to change every programs path to e:/Program Files. And also some programs install to c: automatically.

Its Home Edition. For reinstalling the software, Its too much time, and I dont have alot of the CD's since i borrowed alot.

  Never got an answer from you here..........this  is the place you can make changes for what you asked for......

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSIServer

Does the image path in the right pane correctly point to: (modify drive letter as needed)
C:\Windows\System32\Msiexec.exe /V

also if  you want there is a tweak from Kellys-Korner on Line 94, there is a link at the link section of this site.....as you know make a copy of this part of the registry b4 so you can revert back if need be.........
