Restore registry key

During a diagnostic/repair session with an MS Tech, regarding a
problem associated with the install of SP3, I was told to Export an
item from the Registry, Save it, then Delete the key from the
registry. The key I Deleted was the one that displays the COM / LPT
PORT entry in Device Manager.

These are the instructions I was given by the MS Tech:

[At this time, let's perform the following steps to troubleshoot:

1. Click "Start", go to "Run", type in "regedit" to open the Registry
Editor
2. Click the "+" mark in the left pane one by one to expand and then
navigate to the following key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E978-
E325-11CE-BFC1-08002BE10318}]

2. Right click {4D36E978-E325-11CE-BFC1-08002BE10318} entry, choose
"Export" and save it as a backup.

3. Right click it and choose "Delete".]

When deleting that key did not fix the problem, the Tech passed me off
to a higher level Tech, who hasn't been able to fix the problem
either.He has left me swinging in the wind for several weeks. No
response to multiple email requests for additional suggestions.
Called the 800# and gave up after waiting a 1/2 hour. So much for MS'
FREE support for SP3 related problems.

I would like to be able to see the COM / LPT PORT entry in Device
Manager, so how do I restore that key to the Registry?
 
initiate a system
restore point.

First of, try System Restore to a point before the removal of the COM/LPT
from device manager.

If that didn't help can you compare these entries on your Registry Key:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Ports]
"COM1:"="9600,n,8,1"
"COM2:"="9600,n,8,1"
"COM3:"="9600,n,8,1"
"COM4:"="9600,n,8,1"
"FILE:"=""
"LPT1:"=""
"LPT2:"=""
"LPT3:"=""

If you can find that export file (it has
a .reg extension (time and date of reg file
should match when you exported it) double click
on it.

If you can find the reg file then use a System Restore point,
pick a Date and time prior to when the tech had you delete the key.

Yes, I Saved It so I could find it. Your suggestion worked, thank
you. Wish I had known it would be that simple. Thought there was an
Import sequence of some kind.

Question, is it possible that the data in that key could be out of
date, or is it static?

Thanks to your above suggestion, I didn't have to do a System
Restore. It has been several weeks since I did the Export, and there
have been several system changes since then, so System Restore was my
last resort.

Thanks to all who responded.
 
Most registry keys don't change, your particular key
I would think remains static.

Glad you fixed it.

It's static. It's essentially a text file with a .reg extension on it
containing the information from the key you exported.

should match when you exported it) double click
on it.
