A. Yes, the last build is 2195 which has been released to manufacturing and will be in the shops February 17th 2000. The only difference is the final build will not have the 120 day expiry which the downloaded build 2195 has and that the CD's for 2195 that have been shipped to testers also has. You can check this with WinInfo (http://www.savilltech.com/wininfo.html)
Microsoft have changed there minds about the MSDN version however and the Windows 2000 build 2195 shipping with MSDN will be the FULL, no expiry version. In an effort to stop pirating it will have a hologram visible on both sides of the CD covering the entire surface!
