gain back write registry privileges to be able to change port setting

By Cebbu ·
I googled about this topic and found few non-workable work around on error "you must have write privileges in the registry for this device in order to modify the device's advanced setting" when changing advance setting under port in device manager in XP Pro.

I have followed some blog like booting on safe mode on administrator account, changing registry {0000, 0001 , etc} to disable deny on all to no avail.

a precise and workable tweaks for this will eventually help me and others

re changing port settings

by ThumbsUp2 In reply to gain back write registry ...

I'm not exactly sure what it is you're trying to do. The only thing on my system that has advanced settings for the port in device manager were the COM ports and the MODEM. None of those would allow me to click the advanced button either. Using the question mark to see what the "Advanced" button was for produced this:

A ISO lets you change the first-in, first-out (FIFO) buffer settings for the COM port. These settings are applicable only to ports and devices that use a 16550 buffered universal asynchronous receiver-transmitter (UART).

So, it appears that button is for changing something that you (and I) do not have the appropriate permissions to be changing. If it is as I suspect, the stuff associated with these settings is hard coded on chips in the BIOS of the motherbard. They MAY be configurable in the BIOS, but I'm not going to go looking for trouble.

So, why is it that you NEED to change these settings causing you to look for a way to circumvent the system? Are you messing with someone else's computer trying to disable it in such a way that they'll never figure it out?

Changing port settings.

by Cebbu In reply to re changing port settings

I am not trying to mess other's computer.

What i am talking about is under port(com&lpt). this tree is expandable, highlighting and right clicking one entry, you can go to it's property and port setting tab.you can then click it advanced tab. this should be accessible.

I thank you for responding to this question but if you yourself do not know the answer, perhaps silence is better.

These are important for you sometimes need to change port setting not just to mess other's computer.

1) We've had more than our share of people seeking information here for less than honorable purposes. And, as there is obviously no way to effectively vet them, prudence calls for caution & restraint.

2) With regards to "if you yourself do not know the answer," unless and until the answer is found, no one, including yourself, can say who does and does not have useful information to provide. Bear in mind that troubleshooting is, by its very nature, a process whereby one makes educated guesses, tries them, and, from observing what does not work, makes additional & more informed guesses, until the problem is either solved or abandoned.

3) I can tell you that, as I have no problem accessing the Advanced settings feature via Device Manager on the machine in front of me, running XP Pro SP1, or a remote client running XP Pro SP2, both being Dell machines, or another remote client, a "white box" running XP Pro SP2, your problem is most assuredly platform dependent. I suggest that you contact the OEM for assistance.

Exactly...... and thank you.....

by ThumbsUp2 In reply to 3 points.

... for putting it so eloquently.

One can not "gain back write registry privileges" that one has never had. Either they're there or they're not. If they're not there, they never have been. Some systems just aren't built that way. My PC is self-built with very few components integrated on the MB. The Advanced Settings for the COM and LPT ports have never been available to me through Device Manager, even when logged in as THE Administrator. Mine are all programmable through the BIOS or physically located on the PCI modem itself. So, yes... they're platform dependent.

Thumbs up in the deep sand

by Cebbu In reply to Probably near zero.... < ...

In as much as i want to discuss this thing to both of you, your ideas are near to none.

If my case is platform dependent and does not show on XPSP1 but XPSP2, There should be tweak for me to be able to gain my registry back.

I just want to thank you for your nonsense reply. Trial only begins when there is idea put to try, none of this was produce by both of you.

Did you not read the reply??
"if you yourself do not know the answer, perhaps silence is better"

Yoda has spoken.
Be silent! And be gone!!

And to jamenchua@: This reply is a nonsense reply, but ThumbsUp2 and deepsand's weren't. You posted your original question. It was by no means clear. So you were asked to clarify. And then became rude!

I find it very unlikely you'll get a serious response now unless you make things clearer. And maybe apologise?

re: Talking in the back row....

by ThumbsUp2 In reply to Thumbs!

Yes, YODA has spoken!

But, I'm only guilty of talking in the back row.... and perhaps passing a few notes back and forth.

It's not worth the skin off the tips of my fingers to try and reply directly to the one who knows it all already!
