Stop Bluetooth

System is old Inspiron1720 with fresh install of Win7 Ultimate 32bit (believe it was originally Vista).  Everything works well except ...stupid OS continually attempts to install Bluetooth, which I do not need.  Throughout the day I'm plagued by the device connect sound followed a few seconds later by the disconnect sound, resource usage spikes during this time causing stutters in whatever I'm doing.  Monitoring Device Manager I noticed "Bluetooth Radio" appears at the first sound and disappears at the second;  this may occur every 20-30 seconds for a couple of minutes or it may be a couple of hours before it recurs.

 

I have:

- stopped Bluetooth Support Service (no effect)

- uninstalled two "Base devices" listed in "Other Devices" in Device Manager (no effect, they reappear at next restart;  these are the not installed bluetooth drivers, all other drivers are accounted for;  disabling these two has no effect either)

- disabled Kaspersky Security Data Escort Adapter (read that this also monitored Bluetooth so may have been trying to start it;  had no effect)

- disabled action in group policy ( as per - answers.microsoft.com/en-us/windows/forum/windows_7-hardware/help-needed-removed-device-from-computer-windows/8f5d2a78-eccb-40f6-ba14-608f7b8ce3e1 ) only effect of this was now getting a popup about driver installation being blocked by policy.

 

This morning, in spite of all the above still implemented, several Bluetooth items were actually installed.  Under "Bluetooth Radio" were a couple of listings (meaningless alphanumeric names), under "Other Devices" the two "Base Devices" were replaced by Bluetooth listings, and also under "Other Devices" there was a "BCM2045" listed (which internet tells me is a Broadcom driver).   From past experience with recalcitrant uninstalls in windows I thought now I could uninstall all this and finally be rid of this irritant.  No such luck.  Sixty seconds later I'm back to square one - install sound...Bluetooth Radio appears, uninstall sound....it disappears.

 

The system doesn't mind that I have disabled the webcam, the soft modem, or the IEEE1394 port ......how do I get it to stop this Bluetooth nonsense?

You say you stopped the Bluetooth Service. Did you mean by stopping it you disabled it in the dropdown box? If you still see the BCM2045 in Device Manager right click and select Disable, not Uninstall.

The Bluetooth service (bthsrv) was stopped in Task Manager/services.  Got the connect/disconnect sounds a few minutes ago, it was the BCM2045 being installed and immediately uninstalled (this file has only been appearing the past couple of days).   ...just happened again as I was typing, lol.

Per my question, you stopped the service but did you disable it.? Right click computer > Manage > Applications and Services > Services. Scroll to the Bluetooth service. Double click, stop the service, then disable it.

I don't have any other ideas other than to uninstall the Bluetooth software with the service disabled. Or possibly catch the BCM2045 device in Device Manager when it appears and disable it if you have enough time to do it. I can't be sure but Bluetooth may be integrated into the Wifi card. If that is the case possibly uninstalling the Wifi driver and substituting a USB Wifi dongle may prevent the Bluetooth from constantly trying to install. 

 

I went to the support site for the 1720 and unless I am mistaken the only OS supported was XP and Vista.

Therein lies the problem:  the only time anything has stayed in the Device Manager listings more than a few seconds was that one time when three drivers and two listings under Bluetooth Radio appeared ...and that occurred shortly after blocking the drivers in policy settings.

 

There are three items under Network adapters:

- Broadcom 440x 10/100 Integrated controller (enabled;  internet is via LAN cord to modem)

- Intel Wireless Wifi Link 4965AGN (disabled)

- Kaspersky Security Data Escort Adapter (disabled)

This is getting worse.  Yesterday this irritant was fairly quiet, a half dozen attempts at installing the BCM2045 in the morning then nothing for hours;  last night I gave up trying to play a game because roughly every ten minutes there was a 2-3 minute cycle of install/uninstall three or four times every 30 seconds, each install/uninstall lasts about 4-5 seconds, during which the system is essentially paused (cursor is frozen, if typing nothing appears on screen until the uninstall is done).  Trying to work this morning is an exercise in frustration - imagine working in ten minute spells interrupted by 2-3 minutes of "da-dunk......da-dunk" every 10 seconds.

 

I did manage to catch the BCM2045 installed long enough to right click and select properties...

"Currently this device is not connected to the computer (Code 45)"

So why is this idiot computer continually trying to install drivers for something that is not even connected?!

(It also notes "Port_#0001.Hub_#0008")

 

Also tried disabling the BCM2045, makes no difference;  this stupid system just continues to install and uninstall a disabled driver (it actually installs it with the "disabled" symbol on the icon).

 

And noticed when the BCM2045 is installed, three instances of "USB Input Device" appear under "Human Interface Devices" in Device Manager, those disappear after the uninstall.  FWIW, the only USB device on the system is a mouse (occasionally connect an external HD).

If possible disable wifi and use Ethernet. Do you still get the problem? Have you attempted to uninstall the Wifi driver and reinstall.

 

Open Device Manager. Select View > Show Hidden Devices. Are there any Bluetooth listings?

 

What is the service tag of the computer?

Service Tag is 8FCKLD1

 

Show Hidden Devices (wow, lol),

Under "Network Adapters":

Microsoft ISATAP Adapter

Microsoft ISATAP Adapter #2

Microsoft ISATAP Adapter #3

Microsoft ISATAP Adapter #4

WAN Miniport (IKEv2)

WAN Miniport (IP)

WAN Miniport (IPv6)

WAN Miniport (L2TP)

WAN Miniport (Network Monitor)

WAN Miniport (PPPOE)

WAN Miniport (PPTP)

WAN Miniport (SSTP)

 

And a new section - "Non-Plug and Play Drivers" - with a list so long it barely fits the screen:

You have always connected via LAN on the laptop? I see nothing concerning Bluetooth in Hidden Devices.

 

I entered your Service Tag into Dell's support site but nothing regarding Bluetooth or much of anything else showed up. Possibly because the computer was originally designed for XP and Vista.

Yes, never used wireless or Bluetooth (don't even have any Bluetooth devices).  Bought the laptop in January at a yard sale to use while assembling a new desktop (old one had just eaten its mobo ...the only original component remaining in it, lol), previous owner had just wiped the HD and installed Win7.  No need for wireless here as it sits on a desk two feet from the modem.

 

Whatever triggers this is intermittent;  sometimes I can use the system for hours with no problems, other times it can't go ten minutes without strings of install/uninstall cycles.  From what I've read it shouldn't be installing Bluetooth unless I plug in a Bluetooth device.

Uninstall the Wifi adapter in Device Manager. After uninstalling reboot. Other than that I don't know what else to try.

Thanks, that seemed to stop the install/uninstall cycles;  in "Other Devices" there are still the two disabled "Base System Device" listings and a disabled "Network Controller" listing.

 

But after a day of peace and quiet the malware removed last month returned, and the install/uninstall is back (though monitoring Device Manager is showing no appearing/disappearing entries ...yet), I'm wondering if there is a connection since both involve networking so reopening that thread (www.bleepingcomputer.com/forums/t/669472/vmxclient/ )
