JSI Tip 5550. How can I disable the registry run keys in Windows XP?

You can disable the following registry run keys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

To disable any of the above keys:

1. Use the Registry Editor to navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer.

2. Add Value Names per the following table, setting these REG_DWORD data types to a data value of 1. A data value of 0 will enable the run key:

Value Name	Key to Disable
DisableLocalMachineRun	HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
DisableLocalMachineRunOnce	HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
DisableCurrentUserRun	HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
DisableCurrentUserRunOnce	HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

When you restart Windows XP, the configured entries in the disabled run key(s) will NOT start.
