Uninstall of Cumulative Updates for SharePoint

Uninstall of Cumulative Updates for SharePoint

I am posting this topic because I am getting many questions from SharePoint Techies that they want to uninstall the CU updated to their farms.

Is it possible: There is no easy way to uninstall a cumulative update package for SharePoint. SharePoint updates are really a one-way street: you can only go forward with them and there's no way to uninstall, roll back, or remove them once you've started the installation process

Reasons: The reason for this is that there are two components to the update process

1)   updating the SharePoint bits installed on each SharePoint server

2)   updating the schemas and configuration of the farm's databases in its SQL Server instances. 

If you uninstall the bits from your SharePoint servers, those databases are still going to be functioning at the level of the applied CU and will not work with your servers
