I installed a 60GB SSD for the Windows 7 OS. I want to keep most software off it and install to the D:\ drive. Can I change the default installation drive?

You can change the registry key of


from c:\Program Files to whatever you want to be your default install folder

No, you can't. Most software will let you install to another drive though at installation time if you choose custom. But you can't force it because it uses the %HOMEDRIVE% environment variable and if you change that, Windows will cease to function.

According to Microsoft, this functionality is by design.

Plus some programs just hardcode it. – surfasb Jul 6 '11 at 4:41
I think it is more likely that installers default to %PROGRAMFILES%. – paradroid Jul 6 '11 at 4:53
