Where are system protection settings stored on the system? In windows XP, this was in HKLM\Software\Microsoft\Windows NT\CurrentVersion\SystemRestore In Windows 7, this key exists, but the only values available are: FirstRun (what is this?) LastIndex (what is this?) RPSessionInterval (set to 1) In a subkey (cfg) I've found a value DiskPercent which is set to 15, but if I look at the properties trough the GUI, the DiskPercent value is set to 3%... Another subkey (Setup_Last) mentions the value "Generalize_DisableSR" which is set to 0, but no matter if I enable or disable SR, this value remains 0... Were is the "Restore Settings" stored? ("Restore system settings and previous versions of files", "Only restore previous versions of files" or "Turn off system protection"? Also: Is the RPGlobalInterval key still available/accessible? Is the RPLifeInterval key still available/accessible, and what does it do? Are the WMI classes (SystemRestore and SystemRestoreConfig) still available and working (I tried and got an empty value for RPGlobalInterval...)? Thx in advance!
