Cumulative Update KB3124200 for Windows 10 Version 1511

Don't count on it, could be coincidence. My Bluetooth button is still lit and my PC does not even have a Bluetooth interface. :)

Hi altae,
Just a thought...
When I was on Win 7, I had disabled my BT device in Device Manager and all was well - BT led was off.
However, after upgrading to Win 10, and also after the followup Win 10 clean install, the BT led was then on all of the time, even with the device still disabled in Dev Mgr.
Disabling BT in the BIOS then sorted the issue - BT led is now off.
As I said, just a thought - you may well have already done this.

here is a interesting question why is blue tooth called blue tooth? Is it blue? The same reason why blu ray is blu ray? I believe the latest cumulative update has a purpose but I guess we haven't really found out what it does. I wonder if we will ever know.????

I believe the blu-ray player uses a blue/violet laser to read the disc - the DVD players used a red laser. Bluetooth I have no idea - makes you blue? Plays the blues?

Blue tooth is from a Danish Viking-king called "Harald Blue Tooth": https://en.wikipedia.org/wiki/Harald_Bluetooth

Why they have used that name I don't know.


I installed this update, but it gave me some minor troubble. Mail-app, Wifi-app and some other apps was now in English ?!?!?!?! My Windows 10 Pro is in Danish, so I really don't know why.
After updating the apps in the WS they are back in Danish again

All good updated NP

Worked for me...smooth upgrade to 10586.36.

I wouldn't say it did nothing! It updated winver and the update history!

Does not install. I am getting Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3124200) - Error 0x8e5e03fb. A clean stand alone copy also failed to install. I must say I had to delete Kaspersky Internet Security just before this, and restore the system. Had messed up Firefox which ha to be reinstalled.

Successfully installed on 2 Desktops and 4 Notebooks today, all 64-bit.
