Hi guys! I want to know how to get back to any system restore point in WinXP professional. My actual problem is that i have sum files with .7z format which open with a compressing agent named as 7z provided by digit!, by mistake i have set it to open with IE. Is there any other way of changing this setting instead of going back to any restore point? If not, plz tell me how to set back to any old system restore point.
