System Restore enables users, in the event of a problem, to restore their computers to a previous state without losing personal data files. By default, the Windows Installer automatically creates a System Restore checkpoint each time an application is installed, so that users can restore their computer to the state it was in before installing the application. If you enable this setting, the Windows Installer does not generate System Restore checkpoints when installing applications. If you disable this setting or do not configure it, the Windows Installer automatically creates a System Restore checkpoint each time an application is installed. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Installer!Turn off creation of System Restore Checkpoints (2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer!LimitSystemRestoreCheckpointing
