NT4 Workstation upgrade

I just upgraded an NT 4 workstation to window 2000.
All the installed application do not appear when I click on Start Programs, but when I check C;\winnt\profiles\all users\programs there are all there. I also noticed that the upgrade did not create a C:\documents and settings folder. I cannot afford a clean install because I no more have the disk for a host of the applications.
