Why are they so many different versions and what are the differences ? The original version identified here was replaced by Revsion 103 in April 12, 2011. Now on May 24th, 2011 there is a WHOLE NEW SP1 with a different update ID and identified as Revision 100 ? We have had problems deploying Revison 102 and were happy to see 103 but why the whole new Revision 100 ?

Hi Hamboney, Thanks for the post! The Windows 2008R2 Service Pack 1 was released at Feb.11 2011, refer to: http://support.microsoft.com/kb/976932 To check your system version, please click Start, input msinfo32 and press Enter. I'm confused about the "Revsion 103" you mentioned. Please clarify the version of your system firstly. Since it's a Server-ralted question, this is Windows 7 forum. I recommend you ask this question in Server forum: http://social.technet.microsoft.com/Forums/en-US/category/windowsserver Regards, MiyaThis posting is provided "AS IS" with no warranties, and confers no rights. | Please remember to click "Mark as Answer" on the post that helps you, and to click "Unmark as Answer" if a marked post does not actually answer your question.
