Recently I applied some Microsoft Critical and Security updates from December 2008 and Jan/Feb/Mar 2009 to both my Windows 2000/XP Prof. clients and now I noticed few of the machines are very slow, especailly the Internet.Any ideas?ThanksDeep Kumar

After checking the issue, it seems this is a general Windows XP/2000 update issue. As this forum focuses on Windows Vista specific issues, you can submit support incident via the following link: http://support.microsoft.com/oas/default.aspx?gprid=6527 For Windows XP related system performance issue, you can also post it to Windows XP forum: http://social.technet.microsoft.com/Forums/en-US/category/windowsxpitpro The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.Sean Zhu - MSFT
