I have installed Windows 7 x64 Professional. At last i can say that the heir of Windows XP is here. The only advantage i find in XP now, is the... folders. They look much more tidy and the preview of media files takes like no time, while in 7 it's a long nightmare. Things that i like in 7: - The number of default running services is already contained (about 40). Even after consulting Black Viper's guide, one can see that from running services, there aren't many that need disabling out of the box. - The new taskbar with ability to pin down buttons. Say goodbye to things like Object Dock, Rocket Dock, etc. You don't need them. - Ready to use Weather Gadget. After Singer's Weather Live had gone payware, this is a relief. - My internet connections works faster than XP. I had observed the same in Vista. Really better browsing experience. - Defragmenter that uses multi-pass technique and "consolidation". Auto-defrag in background. - Aero shake, peek, snap and "show desktop" button on taskbar. They are cosy. - Windows Media Player 12. If it only had the volume mouse wheel control too. Anyway, i decided not to install 3rd party player, it's very good and you can use the 64bit version as default. Very fast and and quite light. - Good hardware support. All my hardware except for printer and scanner, worked with pre-installed drivers. The other 2 worked with Vista drivers. - No need for wallpaper manager. You can set to rotate wallpapers at specified time intervalls. - Built-in 2 way firewall. - The "Backup" utility. It can create "system drive image" and "recovery boot CD". Which means, you don't really need 3rd party imaging software (not sure if all versions have this feature), although size compression seems not the strong point (the image is approximately 45-50% of the original size). But for someone who doesn't want to clutter his system with 3rd party tools, it's a viable alternative. - 64bit native applications do run faster. - It now has native DVD playback and burning ability. - Integrated search can spare you the clicks for going to contro panel. - With the exception of file preview, i don't see much difference in snappiness with XP when opening folders. As a mattter of fact, i didn't feel the need to reduce the visual effects, which is surprising to me. - It's prettier. - It's lighter than Vista and it doesn't "feel" slower than XP. * The bad: - No email client.(One can download Windows Live Essentials, but after reading the EULA about privacy, i went with Thunderbird). - The preview of media files is much slower. - Some folder views are simply confusing. - The photo slideshow forces all photos to fit the screen, on XP you could maintain their original dimensions. - Movie Maker, which on XP was default, isn't in Win7 anymore, but you can download Movie Maker 2.6 as standalone program. - Media codecs are a bit trickier for x64, FFDShow doesn't work properly, you need Win7 Shark's Codecs. - Program uninstalling keeps leaving garbage behind. I wish MS had done her own "Revo uninstaller" built in Windows. - Many security programs won't work. - Some x86 programs won't work too, but the good thing is that it usually alerts you about it in time. Hardcore XP fans, yes, it's time to move on! And if you have 4GB of RAM, then going x64 is the way to go. If not for anything else, Win 7 gives you the chance to get rid of various 3rd programs, which at least in my case, makes the system feel lighter. * For die-hard XP Fans who won't surrender (yes, Bellgamin, you know it's you), a chance to "feel" a bit like Win 7 in XP.
