现在想切换WSUS SERVER至WINDOWS SERVER 2012。这个WSUS已作为一个ROLE FEATURE合成到系统里了。
可以迁移WINDOWS 2008上的WSUS 3.0 SP2过来，但也麻烦。
还不如弄了重新干。
GPO再重弄一下就OK了。
WINDOWS布置就是比较快。
但，真的只是简单的卸载就可以了么？？？
显然，我试过，不OK的。让你再重装是，失去的一切都会回来，原来WIDS没搞定呀。
找文档，一步一步来。
How to manually remove all of WSUS

Hey, let's face it, bad luck can strike the best of us, so if you find yourself in a position where your WSUS box is corrupt beyond repair, the regular uninstall isn't working and you have no choice but to do a complete removal and reinstallation then maybe these steps by Ellis George will help you get through it a little easier. These are specific to the SP1 version but should be OK for others as well. Keep in mind that this is a measure of last resort and should only be used if you have no choice but to manually remove WSUS. This will also remove WIDS so when you're done you'll be able to reinstall and start from scratch.
WARNING: Do Not Do This if you are running WSUS on SBS 2008! SBS 2008 installs Sharepoint and WSUS on the same server and both applications store their database in Windows Internal Database. Removing Windows Internal Database (MICROSOFT##SSEE) using steps 6-8 will break Sharepoint and anything else you may have installed that relies on Windows Internal Database.
========
1. Please download and install the Windows Installer Cleanup Utility. To install it simply run msicuu2.exe.
2. Once it is installed go to Start>All Programs>Windows Install Clean Up
3. Scroll through the options and highlight Microsoft Windows Server Update Services 3.0 SP1 (3.1.6001.65)
4. Click remove
5. Open a command prompt and run the following commands:
net stop wsusservice
net stop wsuscertserver
sc delete wsusservice
sc delete wsuscertserver
6. When complete, go back to the Windows Installer Cleanup Utility and highlight Windows Internal Database (MICROSOFT##SSEE) and click remove.
7. Go back to the command line and run the following commands
net stop mssql$microsoft##ssee
sc delete mssql$microsoft##ssee
8. Delete or edit the associated reg keys as noted below:
a. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server and edit the "InstalledInstances" value and remove "MICROSOFT##SSEE"
b. Remove the "MICROSOFT##SSEE" subkey under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
c. Remove the "MSSQL.2005" subkey under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server
d. Rename the following folder:
\%Windir%\SYSMSI\SSEE\MSSQL.2005\MSSQL\Data
to
\%Windir%\SYSMSI\SSEE\MSSQL.2005\MSSQL\Data.old
At the completion of this you should be at a point where you can reinstall WSUS from scratch if you like.

Thanks Ellis!
