Re: modify regedit.exe beginner Q

Tech-Archive recommends: Fix windows errors by optimizing your registry

Thanks for the responses,

So far I was able to change the permissions and delete
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\LPTENUM. It disappeared
from the list. However, when I restart the PC, the HKey LPTENUM is back in
the registry and the FoundNewHardWiz pops up again.

Let me explain what I did. Likely I missed something elementary. Sorry for
being verbose.
In regedit.exe, I located LPTENUM. Right click permissions, there are
two groups listed: “Everyone” has nothing highlighted, and “System” has
“full” and “read” checked, but in dull grey font. Then, following
Nepatsfan’s instr:
Hit the Add button.
The "Select Users or Groups" dialog should pop up.
Hit the Advanced button.
In the expanded dialog, hit the Find Now button.
In the bottom pane, click on Administrators so it's
highlighted.
I get the choices “Administrator” in Desktop folder or “Administrators” in
Desktop folder. Also many other options including my own name.
I select Administrator and hit OK in two different dialog boxes. Now in
Permissions for LPTENUM, there is an Administrator category with Full
checked.
I close Regedit and reopen, try to delete the LPTENUM. I get “cannot
delete. Error while deleting key.”
I restart the PC in safemode, log in as administrator, type regedit and
delete the LPTENUM key OK. It disappears from the list, at least. When I
reboot, the pesky HKey is back.
Another attempt was in regedit, I can change permissions for “Everyone”
and give “Full”. Then I can right click, delete the LPTENUM. Still, as soon
as I reboot, the LPTENUM is back in the registry and the FoundNHWiz pops up.

I hope I understand the MS article correctly. It seems straightforward.
The LPTENUM key I guess is not really deleted or being reimplemented on
boot-up by default to protect against ignorant users. The Canon printer is
new (Pixma MP450-from Oct 06) and definitely plug-n-play. The Panasonic
camcorder is 5 ½ yrs old, but the PC detected immediately when I plugged it
in with a new Firewire cable. It wasn’t detected in the past, but replacing
the cable solved that issue.

Your tips sound great, but I am usually having a hard time in getting things
done.

Scamp,

The issue of the wizard popping up even when the printer is
already
installed is described here:

First off, have you tried uninstalling and reinstalling your
printer and camera? How about going to the manufacturer's web
site and looking for an updated driver for these devices?

As for your registry editing problem, Microsoft left out an
important piece of information in that article. In order to
delete that registry key you have to have the correct
permissions.

Let's start with the easy stuff. Elmo already has shown you how
to add the Run box to your Start menu. Another way to launch
the Run box is to hit the Windows and R key at the same time.

Before you go editing the registry, it's a good idea to create
a restore point. Go to Start -> All Programs -> Accessories ->
System Tools -> System Restore. Select "Create a restore point"
and hit the Next button. Enter something appropriate in the
description box. Hit the Create button. Once the restore point
is created hit the Close button.

Now here's how to delete that registry key.
Open the registry editor (Windows key + R key -> regedit.exe).
Navigate to the key you want to delete.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\LPTENUM

In the left hand column, right click on that key and select
Export from the menu.
The "Export Registry File" box should pop up.
Enter LPTENUM in the "File name" box and save it to a handy
location such as your Desktop.
Back in the registry editor, right click the LPTENUM key in the
left hand column again but this time select Permissions from
the menu.
You should now see a "Permissions for LPTENUM" *** displayed.
Notice how the Everyone group only has Read permissions. That's
why you can't delete the key. You have to add the
Administrators group and give it Full Control.
Hit the Add button.
The "Select Users or Groups" dialog should pop up.
Hit the Advanced button.
In the expanded dialog, hit the Find Now button.
In the bottom pane, click on Administrators so it's
highlighted.
Hit the OK button twice.
You should now be back at the "Permissions for LPTENUM" ***
with the Administrators group added and highlighted in the
upper box.
In the lower box under "Permissions for Administrators", click
on Full Control so it's checked.
Click OK.
You should now be able to delete that registry key.
Restart your computer and follow the rest of the procedure
outlined in that Microsoft article.

Good luck
