Windows Installer |
This tweak prohibits Windows Installer from generating and saving the files it needs to reverse an interrupted or unsuccessful installation. This tweak prevents Windows Installer from recording the original state of the system and sequence of changes it makes during installation. It also prevents Windows Installer from retaining files it intends to delete later. As a result, Windows Installer cannot restore the computer to its original state if the installation does not complete.
This tweak will reduce the amount of temporary disk space required to install programs. Also, it prevents malicious users from interrupting an installation to gather data about the internal state of the computer or to search secure system files. However, because an incomplete installation can render the system or a program inoperable, do not use this setting unless it is essential.
Steps for applying this Tweak
- Open your Registry
- Go to HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer
- Create or modify dword called "DisableRollback"
- Set value as 0 to disable or as 1 to enable this tweak
- Restart windows or logoff for setting to take effect
