Can anyone point me to documentation of the effect wherein HKCU registry keys showing to regedt32 and apps change when the user's account type is changed? A user of account type Standard installed an app which created some config keys, and regedt32 showed these keys fine, under HKEY_CURRENT_USER\Software\ . But they are invisible when the account is changed to account type Administrator, and reappear when it is changed back to Standard. Even odder is that when the app runs from the user as Standard, the key values it receive appear to be those from the Administrator version. This caused a nasty data loss bug in the apps output, so I'd like to understand the cause. Thanks.
