How-to remove Visual Studio 2008 Pro manually?

I've installed Visual Studio 2008 Pro, then installed Visual Web Developer 2008 Express Edition (VWD) using Microsoft Web Platform Installer 2.0.
After few weeks, I decided to remove VWD using Revo Uninstaller. Unfortunately, I've deleted all registry items displayed in Revo Uninstaller's list. So, I cannot using VS2008 any more.
I've tried to remove VS2008 using built-in uninstaller but it's failed. After trying to search through Google, I have found this tool: Windows Installer CleanUp Utility.
Thanks God! Using this tool, I could remove VS2008 and then re-installed it successfully!
