I think I've hosed this system. I inherited an NT 4.0 Workstation system, SP5, with IE 5.5 on it. It did not have Active Desktop installed. I wanted to install Active Desktop, but had read that the way to do it is to uninstall IE 5.x, then reinstall IE 4 with the Desktop Update option. So I uninstalled IE 5.5. That went OK, but left me with NO IE at all (previous version info deleted, maybe?). Luckily (or not) it had Netscape on it also, so I downloaded and installed IE 4. Now when I reboot, it gets all the way to the desktop wallpaper, then Dr. Watson pops ups saying EXPLORER.EXE caused an access violation at such-and-such address. Close Dr. Watson, and it pops up again with an error from Explorer.exe at a different address. After popping up about 30 times, explorer will finally load...but to a blank desktop with no taskbar, icons, no right-click menu, nothing.
What should I do? One thing I didn't inherit was a set of startup disks (yeah, stupid me, I should've made a set first thing) Any ideas, or am I screwed?
The one thing I can bring up from the blank desktop is Task Manager, from which I can run a few things like regedit and command prompt. Any suggestions on a recovery plan, like exporting the registry?
One thing I should mention, there is actually a second installation of NT on the hard drive, but that one is only accessible with an Administrator password (from the business this computer originally came from). Any way, like from command prompt, to copy my profile to the second NT to be able to access it?
Man...I have hosed this bitch...all I wanted was the freakin' Quicklaunch toolbar...

Nevermind, I was finally able to get it to the desktop, then uninstalled Active Desktop. Everything's fine now. Now, I shall make some startup disks...
Thanks anyway.
