If you plan to upgrade your WinFX bits with the yesterday released January 2006 CTP of WinFX Runtime Components consider the following:

You do not need to do a fresh reinstall, even though that is what is suggested in the docs:

• Reinstall procedure works on Windows XP SP2 (x86 and x64)
• Reinstall procesure workd on Windows Vista 5270 (December 2005 CTP)

First, uninstall all December 2005 CTP bits in the following order:

1. Visual Studio 2005 Extensions for Windows Workflow Foundation (December 2005 CTP)
2. Visual Studio 2005 Extensions for WinFX (December 2005 CTP)
3. Microsoft Command Shell (December 2005 CTP, comes with Windows SDK)
4. Windows SDK (December 2005 CTP)
5. WinFX Runtime Components (December 2005 CTP)

Then, invert the installation process:

1. WinFX Runtime Components (January 2005 CTP)
2. Windows SDK (January 2005 CTP)
3. Visual Studio 2005 Extensions for WinFX (January 2005 CTP)
4. Visual Studio 2005 Extensions for Windows Workflow Foundation (January 2005 CTP)

For now, I can't see any major differences in programming model of January <> December WinFX CTP.
