Source of Exchange Server A Reboot From a Previous Installation Is Pending Error
Exchange Server is a product that inherently has and requires many prerequisites, interacts with the operating system during installation, and may require some components to be restarted. This error message (A reboot from a previous installation is pending) indicates that there is a reboot operation on the Windows operating system that has not been started before.
Usually, such pending restarts are caused by updates to the system, configuration changes, or the installation process of other software. Windows Registry keeps track of the changes made and pending restarts, and checks these records during the Exchange Server installation process. Therefore, if the previous installation or update was not completed or a restart was not performed, you may encounter this error message during Exchange Server installations.
If a previous program or Windows update did not install successfully, Windows and other programs may think a restart is necessary. In that case, you will continue to see this error every time you run Exchange Setup (the failed installation cannot fix the condition that indicates a restart is necessary).
