Tim Sneath links to the online documentation on Windows XP SP. 2 (beta) and says “Lastly, I don't think it's quite as bad as people are fearing. The changes that are being made protect end-users from the increased threat posed by worms, trojan horses and spyware today, and for most applications will go unnoticed. Once you read the specifics about the changes made, you'll hopefully agree that only a very few niche applications will require modifications to work in the new environment.“ There is a good documentation which helps you configure your system if some of your apps are not working after installing Windows XP SP. 2.
I feel that this is true, although not many people who complain have used the Windows XP SP 2 beta, they keep on complaining and sometimes just based on the screen dumps they see on the Internet, not fair I think. Sometimes I see people don't know what they are talking about, but still want to join the band wagon and start complaining about the MS products and when I ask them why don't they start using a non Microsoft OS they say “other OS are not good as a desktop system“!!
I would rather prefer that these people instead of complaining help Microsoft by giving feedback on what to improve and how to improve.
