由于需要开发Windows Embedded CE 6的程序，所以保留了一台XP的PC，但是官方的Windows Phone Developer Tools不支持Windows XP，在网上找了一个曲线救国的方法，成功在XP上安装上Windows Phone Developer Tools。
方法如下:
1. Download the Windows Phone Developer Tools RTM
2. Extract the contents of the setup package by running vm_web.exe /x and choosing a path to extract to
3. Go to the folder you extracted to in step 2 and open the file baseline.dat in notepad
4. Look for the section named [gencomp7788]
5. Change the value InstallOnLHS from 1 to 0
6. Change the value InstallOnWinXP from 1 to 0
7. Save and close baseline.dat
8. Run setup.exe /web from the folder you extracted to in step 2
[gencomp7788] BlockorWarn=1 CleanCost=0 CommandLine=blocker.exe ComponentType=1 DetectKey= DetectKeyVal= DetectKeyValData= EncryptionOpt=0 EstInstallTime=0 Executable=sp.exe IgnoreLaterVersions=1 GFN=GFN_MID Block on all OS except Vista and Win7 HelpLink=WPDT_OSRequirements.htm InstallOnAMD64=1 InstallOnFutureNT=1 InstallOnVista=0 InstallOnWin7=0 InstallOnLHS=0 InstallOnIA64=1 InstallOnNetServer=1 InstallOnWin2k=1 InstallOnWinNT4=1 InstallOnWinXP=0 InstallOnx86=1 InstallOnWin7Server=1 LangSensitive=optional moduleid=61862971-5445-44AE-87AE-3EA15736F848 Reboot=0 RebootLaterOk=1 ReturnType=IeReturnCheck Uninstall=0 VersionCheck=Blocker
注意，如果不是使用Windows 7和Vista，注意需要为相关系统安装相应版本的SP
Windows XP Service Pack 3
Windows Server 2003 Service Pack 2
Windows Vista Service Pack 2
Windows Server 2008 Service Pack 2
Windows Server 2008 R2
测试发现，Emulator运行时出错，其他工具没有问题。我想应该是DirectX和WDDM的问题，再查一下。 毕竟不是官方支持的工具，使用时有风险。
