This per-machine system policy turns off the creation of checkpoints by Windows Installer.
Set to 0 or absent, the installer does normal checkpointing for install or uninstall. Set to 1, the installer creates no checkpoints.
This policy affects only checkpoints set by Windows Installer. On Windows XP computers, administrators may decide to disable checkpointing from within Windows Installer to improve performance. System Restore also creates additional checkpoints. For more information, see System Restore Points and the Windows Installer and Setting a Restore Point from a Custom Action.
Set the value named LimitSystemRestoreCheckpointing under the following registry key.
