Sorry the answer is still no. It's been no since about Windows 95 and has shown no sign of changing.
HOWEVER there a few PORTABLE APPLICATIONS that would work under such conditions. Here's a link about them -> http://portableapps.com/
I currently have Windows XP installed on my tablet PC, but I'd like to test out the Windows 7 Release Candidate. I've watched the cnet video explaining the dual boot process, and I'd like to create a new partition on my internal hard drive for Windows 7. The problem is that I'd like to be able to use my currently installed programs in Windows 7 without installing them again, thus taking up more precious disk space (otherwise, the only thing I'll be able to do within Windows 7 is use the internet and play around with the new OS, unless I'm not understanding dual boot correctly). Is there a way to do this? I REALLY don't want to have to reinstall a bunch of programs. Thanks!
