When you say reset to zero are you saying to simply type 0 in the data section and close? Not 00. as they appear.

Thanks.

Awesome, this worked a treat in Windows 7 32-bit on a bunch of Com Ports that showed open/still in use even after removing ghosted devices.

(I found Ghostbuster for that)

Thanks so much!

Awesome, thanks! For those worrying, I set all to 0 on my Win7-64 (pro) and COM1 and LPT1 were both preserved. We're good now.

Pure Genius! Thanks.

This helped me out no end when trying to use a bluetooth OBD2 ELM327 interface, where all of the freeware available has a limit of comm ports 1-8. Thank you very much.

Looked at my registry, and value was 1c. The last device I added was COM5. I deleted it, and the regis. val. was 0c. Knowing that the binary for 1c was 00011100, I concluded that the bits, right to left were for COM1-COM8. Wrote the Registry from 0c to 08 (thinking I'd free COM3). When I reinserted the device I had deleted, it was assigned COM3. Looks like you can selectively clear COM port numbers, if you choose. Also, looks like COM1 and 2 are already zero - and not available to the user.

I used this procedure months ago when my Win 7/64 machine got itself up to about comm10. It works perfectly and is completely safe if you're comfortable poking around the registry.

Can someone test this in Windows 7 32 & 64 bit O.S.? Also, it should be noted to uninstall and then unplug any serial to USB adapters/harware.

Will resetting the port arbitor work in WinVista and 7 as well? Will it wipe out Windows physical ports COM1 & 2? Thanks!

Mahesh, will this wipe out physical COM ports in Windows as well and make, say COM1, unavailable?

Thank you - I've wondered how to do that for a long time now. Mine was up to com55! Now everything's more sane - you rock.

Thanks Mahesh,Very useful information, just one suggestion, can you please make those screenshots in PNG instead of JPEG, will be more clear and also will ease for you in uploading.
