I have only had Win7 installed a few days, and so far I like itvery much,but I think it is basicallyVista with the problems solved that should have been solved a year ago.It's great that the problems with UAC and other issues (like slow copying, etc) have been fixed, butother than that, many of the changes seem cosmeticand not really worthy of being called a new OS. I truly feel it should be a service pack(orthere should be a minimal upgrade price for those who already own Vista.) Just making things work as they should, such a hardware drivers, does not merit a couple hundred dollars for an upgrade. It looks as if there are some Network security changes, as well, but they should have been in Vista based on the way it was promoted as being so secure.Perhaps for system administrators there are worthwhile changes which I wouldn't know about, but for the average home user, it would be a ripoff to have to pay several hundred dollars to upgrade to Win7. Vista should work the way Win7 works. If you have been usingWindows 7longer than me and know of other changes, please post. (And will the home version have fax capability, something I feel MS was very remiss in not including in Vista Home Premium?)

Hi JoRene Go to the following website.Welcome to Engineering Windows 7There are 3 dozen articles there written by the Windows 7 Development team that detailsmost of the core changes that are beingdesigned and implementedin Windows 7.Windows 7 also includes support for newer technologies that were not availabe when Vista was released.Hope this helps.

Plus there is considerably more than what is described in the E7 blog (good pointer Ronnie), such as functionality thathelp millions of business and laptop users:DirectAccess, BranchCache, Agile VPN, rewritten power management, rewritten offline files, thousands of new group policies, PIV/PNP smartcard system, rewritten software restriction policies, offline domain join, massive kerberos and NTLM capabilities changes, rewritten credential manager, new RSAT tools, powershell V2 with cmdlets added for AD/NLB/Cluster/GP/etc. And the changes in Windows Server 2008 R2 are far more considerable.As well as all the things outlined here in Kernel changes by Mark Russinivich:http://channel9.msdn.com/shows/Going%20Deep/Mark-Russinovich-Inside-Windows-7/"How has Windows evolved, as a general purpose operating system and at the lowest levels, in Windows 7? Who better to talk to than Technical Fellow and Windows Kernel guru Mark Russinovich? Here, Mark enlightens us on the new kernel constructs in Windows 7 (and, yeah, we do wander up into user mode, but only briefly). One very important change in the Windows 7 kernelis the dismantling of thedispatcher spin lock and redesign and implementation ofitsfunctionality. This great work was done by Arun Kishan (you've met him here on C9 last year). The direct result of the reworking of the dispatcher spin lock isthat Windows 7 can scale to 256 processors. Further, this enabledthe greatLandy Wang to tune the Windows Memory Manager to be even more efficient than it already is. Mark also explains (again) what MinWin really is (heck, even I was confused. Not anymore...). MinWin is present in Windows 7. Native support for VHD (boot from VHD anyone?) is another very cool addition to our next general purpose OS. Yes, and there's more!"No one is forcing you to upgrade to Windows 7. We will be releasing Vista SP2 before you know it and Vista will be supported until 2017. That isthe beauty of Windows - wewrote the book on backwards compatibility and long lifetime operating system support.However, if you want new functionality, you must purchase it.
