SharePoint 2010: Uninstallation

SharePoint 2010: Uninstallation


 This topic is a how to.
Please keep it as clear and simple as possible. Avoid speculative discussions as well as a deep dive into underlying mechanisms or related technologies.

To remove or uninstall SharePoint 2010, do the following:

  1. Login with local administrator user.
  2. Go to "Add/Remove programs" under Control Panel of Windows Server 2008.
  3. Then right Click on Microsoft SharePoint Server 2010 and choose "Uninstall".



  4. Choose Remove from the wizard.
  5. Then continue by ignoring all warning messages.
  6. After the wizard is finished, then you can also remove the language packs for SharePoint if exists.
  7. Reboot the server to complete the un-installation.

Notes:

If you want to re -install the SharePoint in the same server, it's best practice to go with clean windows because the uninstalling SharePoint 2010 does not remove everything and there are still some items exist in the server like /14 folder , SharePoint Web Services Web application and its application pool in IIS and some development customizations.

Removing SharePoint server 2010 wont delete the configuration databases which were created during the execution of PSConfig wizard. If you are trying re-build after the removal process, also ensure the configuration databases are also cleaned up.

When the uninstall process is complete, you will see a final page that tells you that the uninstall has completed successfully, so you should now have a SharePoint-free server. However, after successfully performing an uninstall, note that the following SharePoint characteristics still exist on the server.
  • C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14
  • Microsoft SharePoint Workspace Audit Service
  • SQL databases including Configuration and Central Administration
  • SharePoint Web Services Web Application in IIS 7.0
  • SharePoint Web Services Application Pool in IIS 7.0

To reiterate once again the point about doing fresh installations of your software, these items all still existed on a server after performing a complete installation of SharePoint 2010 and then a removal of SharePoint. Always perform clean installations—this includes starting with a new operating system installation, not an upgraded operating system

If you are connected to a farm, you will need to Disconnect from the Farm. After the Farm disconnects, there is still work to be done on the SQL Server and the servers disconnected from the Farm. Next, navigate into the Control Panel -> Programs and Features to Uninstall Microsoft SharePoint Server 2010

Reboot the Server where you uninstalled SharePoint.

1) SQL Server(s) cleanup:

  • Remove the configuration, content, administration, search and user profile application databases

2) The server(s) connected to the Farm which were running the SharePoint Foundation Service, the IS application pools still exist after the uninstallation.

Perform the following:

  • Remove the Application pools and Websites
  • Remove the 14 Hive located at c:\program files\common files\Microsoft shared\web server extensions\14
    • It is very important to remove this directory manually

This should be as close to a full uninstall as you can get without digging into the Program files directory or GAC. If anyone has input to the Program files directory or GAC removal, feel free to follow up.
