- * Network Interoperability: Many of the familiar simplistic network and file sharing functions of XP are much more involved in Vista. The selling point is supposedly that this makes the operating system more secure and more granular regarding ability to allow or disallow certain operating system features. Yet, when it takes undue effort and trial-and-error to simply share a folder between Vista and an existing Windows XP network, with no clear indications as to the exact steps needed; nor adequate troubleshooting guides, this becomes an incredible hindrance to productivity.
- * UAC - User Access Control: This allegedly makes Vista more secure, but is a huge annoyance and hindrance, in basically having to say "Yes, I meant it when I asked you [Vista] to run this command." UAC can be disabled and, granted, likely does provide yet another measure of 'defense in depth,' by not allowing an automated script to inadvertently run without explicitly getting the user's approval. Therefore, if UAC is enabled, it is unlikely that a mere hijacking script would be able to easily circumvent the controls of your workstation, since the process effectively would be running only in the 'user' context and not the elevated 'administrator' context.
Conclusions
This article points out that it is apparent that Microsoft made some erroneous and not-well-thought-out assumptions when it assumed that Vista would be quickly and readily adopted, no questions asked, by the private and business sectors. In short, Microsoft did not anticipate the thoroughly entrenched XP user base to be so fiercely loyal as to be resistant to upgrading to Vista. Microsoft also must have had some false assumptions in thinking that it had effectively "sold its case" for the need of businesses to upgrade to Vista. Clearly, a combination of existing happy XP users, cost-conscious IT managers, wary hardware and software manufactures, and shrewd consumers know better what they want than Microsoft thinks it knows.
