How To Programmatically Change COM Port FriendlyName
May 18, 2010
I have an installation script that changes the COM port numbers based on certain hardware that is installed. In Windows 2000, I use regini.exe to import the listing of registry entries below. The reason for this was to allow the permissions on the FriendlyName value to be changed.
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnumACPIPNP05011
Device Parameters
PortName = COM5
[Code].....
I tried this same process in Windows 7 and everything works except for changing the FriendlyName value. The only way I've been able to change this value is to manually (in regedit) "take ownership" of the "1" key and then change the permissions to Full Control. However, I need to do this in a script to make it transparent to the user.

I have a Touchmate PC with two sets of audio ports (3.55mm jacks or 1/8" ) the front ones are not working (because they are disconnected) so i wish to use the rear ones, however, windows is set up so that the audio output (into my headphones) send information through all ports but the front mic, which is fine because i use the rear output port. My problem is that the microphone settings will only allow the microphone to be read through the front microphone port. Is there any way i can change these settings so that the microphone reads through the rear microphone port.

I need to change the port settings, but get message that I don't have "write" permissions. I tried this approach:
Run Regedt32.exe, find
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnum
now right click Enum , and goto permissions..make sure either Everyone or your
account are set to Full
But got same error message when I tried to make the change.

Last night my new laptop arrived (XPS), still getting used to windows 7 etc... but i thought i would watch something through my t.v. Plugged HDMI cable in back of laptop straight in to t.v, changed the source and straight away i had a lovely sharpe picture of my deskop instantly.... or so i thought
im getting the middle part of my screen fine - but it is cropped so i cant see the tool bar (its too low) and the desktop icons are only veiwable if i move them closer in screen! Ideally i want to have identical screens on both so i can use both at sam time, but currently i can only view either or atm? and the t.v one being crop means i can use it as a computer (No toolbar etc..)
I could figure this out on XP but windows 7 seems beyond me atm!

To all the computer geniuses out there, I guess this isn't a windows 7 problem but it's about drivers.I have an Asus K53E-B1 with Windows 7 64bit. It comes with 3 USB 2.0 ports and that's it. I went on the Asus website today and found USB 3.0 drivers update.I can't just download those drivers and use them and expect USB 3.0 performance when I have USB 2.0 ports right?

I just installed Windows 7 and updated all my drivers. I am missing two drivers, and I don't know what they are:
PCI Serial Port
PCI Simple Communication Controller
What exactly are these? I own a Lenovo X200 Tablet. Any ideas where I can find the drivers for these two things?

I have a quick question about the USB ports on my computer. I have a screenshot hosted here on Flikr: USB | Flickr - Photo Sharing! Of the 5 USB's that are listed, one is a USB2. Is the USB2 Enhanced Host Controller a USB2.0 port? I am looking because I am going to buy an audio interface and if I have a 2.0 in there then I will get something a little better 'cos I want as little latency as possible when recording vocals.
There is one other thing also, if it turns out that there is a 2.0 port, is there a way to physically differentiate which port is the 2.0? I have 3 USB's on the back and 2 on the front of my tower. At the moment I don't know which is which and do not know what to physically look for when I look in or out of the case.

New PC has a 1394 Port.
Familiar with the USB Ports of course, but have never used a 1394 Port.
What and where is it used ?
For what ?
What devices should utilize it ?
And whatever else I'm not sharp enough to know to ask about these Ports, please ?

I use my computer aboard a 47' Sailboat primarily for navigation and communications. As such, I run multiple external devices. To name a few:
WiFi Cards (2)
GPS
Pactor Modem
Iridium Satellite Phone
Verizon Aircard
Telcel Aircard
You get the picture. I was unable to accomplish a very simple task using VISTA, to wit, being online with my Verizon Aircard and using one of the WiFi cards to access my wireless printer.
I finally downgraded to Windows XP and this is never a problem anymore. A Verizon tech once gave me an explanation of why this couldn't be done in VISTA, but unfortunately the explanation went over my head.
Does anyone know if this problem has been fixed in Windows 7, or does that OS have similar problems as VISTA handling multiple communications devices operating simultaneously on different USB ports?

I have spent the last two hours trying to open a port for a remote control application.
I have tomato 1.27 running on an asus wl500gP router.
I am running windows 7 ultimate
i have an Arris voip modem through comcast
The problem is this, i forwarded the port correctly in tomato yet the port is still closed. I have tried the following:
Enabling DMZ
Disabling windows firewall by either the control panel or through services.msc
Enabled UPNP in the application, it opens the port according to tomato yet external port testers still say its closed
reset the router and pc numerous times
hard reset the router
Hooking PC directly into cable modem
I believe that this is strictly a windows 7 issue now as the router is out of the equation. The only security software I have is Avira free edition, windows defender, and (disabled) windows firewall.
Can anyone give me help as to why I cannot open a port? It would be greatly appreciated as I am leaving for a trip in 36 hours and would like to be able to remotely control this application.

I tried to change the default remote desktop port from 3389 to some other 4 digit number.
I did this via regedit
HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Terminal Server WinStations RDP-Tcp
I setup that port correctly as a port forwarder in my router. The original 3389 was working fine. However, the new 4 digit one is not strange enough (port forwarder is 'ok' according to one of those port forwarder checking sites). I tried to RDP from one network to my IP (confirmed correct) like this:
myipaddress:1234
1234 = being the actual port number I set up.
Of course, I do already have RDP enabled on both Windows 7 laptops.
What could be the cause of the invalid connection? It was working fine on 3389 by for extra security measures, I changed it to something else. I did restart the laptop as well.

It's been a while since I've gotten my sound "working," but my current problem is that only one of my audio jacks work, one on the back. I know it's not the hardware because it used to work on vista. It hasn't been that much of a pain because i didn't have to change often between audio output devices, so i just dealt with it- getting back behind the computer and switching out cords. Now i'm doing it a little more frequently, so I can still just deal with it, but if anyone here does know something that may help, it would be very nice of you to let me know.
