Windows Vista

Hello there,
I am a beta tester and I have tested windows Vista(code name longhorn).The first issue I would like to discuss about windows vista code name longhorn is that it has a very powerful sub system powering the graphics and other cool effects which is sure going to churn your c.p.u..

well only graphix are cool but it needs a lot of improvement at this stage to make a successful OS.a lot of bugs are there.

Currently - Windows XP
Service Pack - 2
Additional Patches - 69 (Including Windows Installer 3.1 and Media Player patches)

Upcoming in 2007 (Hopefully) - Windows Vista
Current Status - Released for BETA testers... buggy...
