You can install Windows XP on a computer with Windows 7. (!) Acronis OS Selector allows you to install an older operating system where a more recent operating system is installed: e.g. As a boot manager it allows you to multiboot between several operating systems installed on your computer. Acronis OS Selector is a boot and partition manager.
Since you are unable to launch several Microsoft operating systems simultaneously, other system restore points will not influence the system functionality. System restore points should be taken into the consideration on the running operating system only.
