Registry: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run

The values below HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\Run can be used to enable or disable the corresponding values under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.

A value of 02 00 00 … or 06 00 00 … seems to indicate that the entry is enabled, all(?) other values that it is disabled. (Possibly, in the case of disabledness, the value is the timestamp of the disabling).

These values can be modified in the startup tab of taskmgr.exe.
