I am having some trouble with Windows 7 64-bit and changing the default installation folder.
I like to have a partition only for the OS. I think it is a good practice and that's always been recommended to me by various people. So, I normally have a C:\ parition for the OS and a D: for everything else.
The problem is that when changing the default installation folder from C:\Program Files to D:\Programs it doesn't work all the time. I can't really understand why but believe me, sometimes, even though I change the folder on the installation folder to D: it will install on C:!
Furthermore, when I change in the regedit the default installation directory to D:, I automatically lose some Windows 7 functionality like Windows Sidebar, among others.
I have been digging the internet for a solution for this, but still haven't found one.
I suppose someone from superuser.com has already had this problem and maybe could share his/her knowledge.
