Hi Mark
I found this code at vbacceleratot, has many good things in it, take a
look at it.....
http://vbaccelerator.com/codelib/inireg/regmisc1.zip
Also, in my case I'm running W2kAS, At the point of entry of runonce
I think a lot of background process are already starting up I found
through a search looks like 7 may be more advantages to use as MS
would add/remove programs I would think when nothing of there
system(even though I'm not going to install anything)were not being
held, tell me what you think
the following was found at
Http://support.microsoft.com/support/kb/articles/Q137/3/67.asp
1. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
2. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
3.HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
4. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
5. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServices
6. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunServicesOnce
------------------------
7. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
RunOnce\Setup
------------------------
MORE INFORMATION
Keys 1-4 are run each time a new user logs in.
Keys 5-6 are run in the background when the logon dialog box first
appears, or at this stage of the boot process if there is no logon.
These keys are for background services such as remote registry service
and are run only once per boot.
---------------
Key 7 is run as part of Setup's first-boot activities, or after you
use the Add/Remove Programs Wizard.
----------------
Under each of these keys is a series of values. The values are used to
allow multiple sub-entries to exist without overwriting one another.
The data value for a value is a command line. By default, Run keys are
ignored in Safe mode. For keys 3-4, the value name can be prefixed
with an exclamation point to defer deletion of the value until after
the command has been completed.
For keys 3, 4, and 6, the value is deleted before the command line is
run unless overridden as noted above. As a result, if a RunOnce
operation fails to run properly, the component that failed will not be
asked to run again the next time you start the computer.
-------------------
Key 7 is used only by Setup. This key displays the progress dialog box
as the keys are run one at a time. For key 7, the name of the value is
the name that is displayed in the dialog box.
-------------------
This is more then I ever wanted to know on this topic :)
