About this tag
The tag prelease on WindowsForum.com covers discussions about pre-release versions of Windows software, such as beta or release candidate builds. In one example, a user encountered an issue when trying to install the Windows 7 Service Pack 1 release candidate, receiving a message that a prelease version was already installed and needed to be removed first. The user attempted to uninstall the pre-release service pack using the wusa.exe command but found the uninstall option disabled and received an error stating the service pack was required by the computer. This tag is relevant for troubleshooting installation and removal of pre-release Windows updates and service packs.
