“Bluetooth Device Not Found” After Windows XP Service Pack 3 (SP3) Install

My Dell-branded Bluetooth module disappeared after installing Windows XP Service Pack 3 (SP3). The fix for this solution is pretty simple as long as your device was working prior to installing SP3. The steps are as follows:

  1. Click Start, click Run, type %windir%\inf in the Open box, and then click OK.
  2. Find a set of eight files beginning with “BTH.INF”.
  3. Move following files to a temporary folder:
    • bth.inf, bth.pnf
    • bthpan.inf, bthpan.pnf
    • bthprint.inf, bthprint.pnf
    • bthspp.inf, bthspp.pnf
  4. Click Start, click Run, type devmgmt.msc in the Open box, and then click OK.
  5. Expand the list under Bluetooth Radio by clicking the “plus” sign.
  6. Right-click “Microsoft Bluetooth Enumerator” and click uninstall. Click OK on the next dialog box.
  7. Right-click “Generic Bluetooth Radio” (it may read “Dell TrueMobile Bluetooth Module” or something similar) and click “Update Driver…”
  8. If a dialog box comes up asking “Can Windows connect to Windows Update to search for software?” click “No, not this time”, and then click NEXT.
  9. On the next screen pick “Install from a list or specific location (Advanced)” and click NEXT.
  10. Click “Search for the best driver in these locations.” and put a check-mark on “Include this location in the search:”. Then click BROWSE.
  11. Find the location where the Dell WIDCOMM drivers were installed. On my system this is “C:\Program Files\WIDCOMM\Bluetooth Software\bin”. Click NEXT.
  12. Windows will now install the drivers.
  13. Restart your system if necessary.

Follow these instructions at your own risk! Make sure you backup your computer before attempting this procedure. I can’t be held responsible if you screw up your computer.

    I have this problem, my Bluetooth devine does not operate. I have Service Pack 3, but in item 6 of the recomended procedure, It does not appear the “uninstall” option. What do I have to do?

    folks, that man explained everything, but u cannot expect that all he said would be exactly the same. i couldn’t find that “uninstall” button as well. moreover, i couldn’t find “Bluetooth Enumerator” at all, but i assume that i had previously deleted it (i suppose i’ve done it from the system tray by simply clicking the “remove Bluetooth Enumerator icon” (OR sth like that!!!)). all the rest was the same as descibed. i solved the problem and now i use my bluetooth devices the same way i used to use it while sp2 was installed.
    THANK YOU so much for ur help 🙂
