64bit world, without windows phone sync

From Office 2010, native x64 version is included. The funny thing is, if you install an x64 version of Outlook into your windows, no matter windows xp (x64), vista (x64) or win7(x64), you just cannot synchronize the data between Outlook and your windows phones.

It seems that ActiveSync(xp) and Windows Mobile Device Center(vista and win7) cannot recognize the x64 version of Outlook. And, the x64 version Outlook cannot be installed on the operation system which contains any x86 office components.

If you need to sync your windows phones with outlook, you have to install the 32bit office.

Need we choose the Ultimate version of Windows 7 ?

Windows 7 Ultimate has all functions but it costs much expensive. In many cases, the additional functions are not so useful for us, or we can use some cheaper softwares instead.

Microsoft told us that, if you choose Professional version instead of Ultimate, you will lose these functions:

1 Help protect data on your PC and portable storage devices against loss or theft with BitLocker. (OK, if I really need this, why not to purchase another software instead )

2 Work in the language of your choice and switch between any of 35 languages. (Great, but not needed, at least for me.)

If you choose Home Premium version instead of the Professional one, several functions more are lost:

1 Run many Windows XP productivity programs in Windows XP Mode. (Yes, you may have known that is not so easy for use and cost lots of resources.)

2 Connect to company networks easily and more securely with Domain Join. (I think it’s not necessary at all for a home user.)

3 Recover your data easily with automatic backup to your home and business network. (It’s not the system restore, but a standalone backup tool. And, this is the only one function, backing up to a network destination. You still can backup to your hard disks and removable devices without it.)

And, with the much cheaper version, Home Premium:

Windows 7 Home Premium makes it easy to create a home network and share all of your favorite photos, videos, and music. You can even watch, pause, rewind, and record TV. Get the best entertainment experience with Windows 7 Home Premium.

  • Simplify your PC with new navigation features like Aero ShakeJump Lists, and Snap.
  • Customize Windows to look and feel the way you like by changing themes and taskbar programs.
  • Setting up a home network and connecting to printers and devices is easier than ever.
  • Windows 7 Home Premium supports the latest hardware and software.
  • Designed to make your PC sleep and resume quicker.
  • Takes full advantage of 64-bit PC hardware and memory.
  • Connecting to wireless networks is fast and easy.
  • Watch, pause, rewind, and record TV with Windows Media Center.
  • Watch your favorite DVD movies.
  • Includes integrated video and Dolby audio codecs.

[FW]在Windows Server 2008中启动SuperFetch

SuperFetch是微软Windows Vista系统的特性之一,通过导入大部分由内存中一个应用程序或进程需要的文件或数据,尽可能快地重新将预取数据从虚拟内存页面文件移回到物理内存中以保证性能增强的连续性,所以可以在需要时更迅速地访问它们.而在以稳定见长的Windows Server 2008服务器系统中,该功能默认被禁用,当然您如果正在把WS2008当成台式机系统来用的话,建议重新开启SuperFetch以取得更高的性能,方法如下:
