Maybe not, maybe I just think I did. As I said, I tried it in safe mode and I have full administrator rights, even used an 'admin notepad' approach to insure I wouldn't be blocked, but no cigar. Jimmy's directions do work, the directions to delete the port or to use Print server are for the most part useless, it can depend on how your Network is setup, Domain, etc. If you are here making these types of requests, you are not at a level where you need to be concerned about typing "regedit" and using the Registry.
Listen to Andreas and note, there is a reason his post was marked as the correct answer by MSFT staff. If you are still concerned and if you follow the exact directions Andreas posted, you can't mess anything up, it's not a critical chain, but just back up the registry whenever you do anything. More people have destroyed their PC using CC cleaner to clean their registry, than those who go in on their own. Just learn a bit more and backup. Mastering the registry is what never leads to problems.
No offence, just my 1 cent. If you know the name of the port, you can also remove it programmatically, e. Might be use full for sys admin on a domain with standardized names for IP printers. Remove-PrinterPort seems to be available since Windows 8, so Powershell 3.
Won't be an option with plain Windows 7. I get the error message "The filename, directory name or volume label syntax is incorrect. But I think it is a bit overkill here and most importantly, it won't solve your issue if you can't do it on Windows control panels.
My code will also fails with "requested resource is in use" if Windows is telling so. So I will first try Arthur Xie answer and more specifically tried that logged as an administrator: a printer can indeed by installed by an user and only this user or the admin can un install it.
Same applies for the port that can be removed only once all printers using it are removed. Right on! I also had the "port still in use" even though I deleted the printer. And you are right, it's because the printer test page that failed to print from the bad printer install was still in the spooler!
That of course is a big bad Microsoft bug. To go around it, I exited the printer window, entered it again, the "deleted" printer reappeared with a yellow warning sign. Right click on it, "See What's Printing" to open the spooler, right click on the stuck document, hit Cancel. The printer eventually disappears but not the spooler window nor the doc, another bug.
Close that, now I can delete the port. All these very basic known bugs after all these years. Office Office Exchange Server. Not an IT pro? Windows Client. Sign in. United States English.

You might have to restart the Print Spooler service after deleting that key to see the change go through. As always when working with the registry be careful and to be on the safe side create a System Restore Point before doing the edit. There is an easier way. Please: 1. Wednesday, November 25, AM.
You can do it by starting Print Management printmanagement. Many thanks Andreas, my version of W7 is Home Premium and it does not appear to have Print Management printmanagement.
Non present devices show up with the port number assigned right next to it. Thank you Brian for sharing your wisdom! I have over serial ports in use on my pc is there a way to uninstall several ports at 1 time?
But then I booted in safe mode, and do this procedure. Thanks, this worked for me. The driver initially can up as COM All my lower number COM ports were in use so I found these instruction to clear one of the ports:. Worked like a charm, thanks! I suspected those little bastards were hiding somewhere and now I know how to find them. To those not getting it to work, you are probably not managing to set the environment variable properly step 2.
Hint: You can also find the device manager in the hardware tab in the same dialog, unless you want to show off your command line ninja skills of course. Thanks, worked a treat in Windows 7 no reboot was required when I replaced my motherboard.
The com ports werent working and on checking the ports in use there were twice as many as there should be. Your tip allowed me to get rid of the old ones. For windows 7 32bit, etc, be sure you are in the Windows directory. Type: cdWindows once you are int he command prompt, then follow steps 2,4,5,6 above. Hi Brian, got a quick question…what if you uninstall all the COMs and reboot but the COM ports come back and still show that they are in use when there is nothing being shown for the device s?
Is this machine a member of a domain? If so, you might try logging on as local administrator account and re-follow the steps above. How do you do it there? Ok I figured it out never mind printers, removing to get comports etc..
Com Ports will not show until you connect a comport. Now the reason you have all these unused comports is because drum roll …you have plugged in a multiple USB hub get it?
Then, if you want, plug the hub in and it will assign comports above the lower number one you just installed. Computer will remember the comports unless you remove the lower comport, no worries just repeat the process to get the right comport. Hope this works for you! Sorry this didn't help. Thanks for your feedback. I work with a device that connects through COM port via Bluetooth. Everytime I remove and reconnect the device, a new COM port gets created.
I even tried clicking on "Show Hidden Devices" under device manager but still nothing shows up. How do I delete the unused COM ports? This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread.
