Windows 10: Just ran latest updates and now my Bluetooth is gone

I just ran the latest Windows 10 July updates, and now my Bluetooth is gone. When I brought up Device Manager nothing showed until I displayed hidden devices. When I look at the info for the Bluetooth device Raylink Bluetooth PCIe Adapter it says:"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing" Code39""Windows cannot verify the digital signature for this file. The signing certificate for this file has been revoked"What can I do to fix this?JohnD

Bluetooth Troubleshooter says "device does not have bluetooth", when bluetooth is native on my device

Hi, I have a Dell Inspiron 17-7779 and was having an issue while running a program that utiliized Bluetooth 4.0, where the Bluetooth would be working find, and then the program said Bluetooth was turned off, and when I went to go turn it back on, the option
to turn it on does not exist.

I followed lots of troubleshooting and completed the following steps:

• Restarted my computer (several times)
• Ran "services.msc" and restarted "Bluetooth Support Service"
• Windows said drivers were out of date

Eventually, I came across a Microsoft post that suggested uninstalling the device, which I did. I restarted my computer, and ran Windows Update, and no drivers were installed. In Device Manager again, the Bluetooth device was gone, even when checking "Show
hidden devices" under "View".





I ran Bluetooth Troubleshooter, which then told me that "Device does not have Bluetooth. Bluetooth is not available on this device". I restarted the computer and repeated previous steps several times with no success. I have tried 2 different driver programs
that both do not detect nor fix the issue. I have gone to both the Dell and Intel websites and tried to install the latest driver. The driver that was downloaded that I installed was the "Intel(R) Dual Band Wireless-AC 3165". Restarted computer. Restarted
Bluetooth Support Service. Still, my computer fails to recognize that it even has Bluetooth.

Does this leave me to do a system reset?

Help/suggestions are greatly appreciated.

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Bluetooth Technology Gets Faster With Bluetooth 3.0

From its annual All Hands Meeting in Tokyo this week, the Bluetooth SIG formally adopted Bluetooth Core Specification Version 3.0 + High Speed (HS), or Bluetooth 3.0. This latest iteration of the popular short-range wireless technology fulfills the consumers' need for speed while providing the same wireless Bluetooth experience – faster. Manufacturers of consumer electronics and home entertainment devices can now build their products to send large amounts of video, music and photos between devices wirelessly at speeds consumers expect.
Bluetooth 3.0 gets its speed from the 802.11 radio protocol. The inclusion of the 802.11 Protocol Adaptation Layer (PAL) provides increased throughput of data transfers at the approximate rate of 24 Mbps. In addition, mobile devices including Bluetooth 3.0 + HS will realize increased power savings due to enhanced power control built in.


"Like Ricky Bobby in Talladega Nights, this latest version was 'born to go fast,' said Mike's Blog, Ph.D., executive director of the Bluetooth SIG. "Utilizing the 802.11 radio was a natural choice as it provides efficiencies for both our members and consumers – members get more function out of the two radios they are already including in devices, and consumers with Bluetooth 3.0 + HS products will get faster exchange of information without changing how they connect. We are excited to expand the possibilities of the PAN."

This newest version of Bluetooth technology builds on the inherent qualities of the current 2.1 + EDR version, including Simple Secure Pairing and built-in, automatic security. And as with all versions of theBluetooth specification, v3.0 + HS provides developers, manufacturers and consumers with the benefit of backwards compatibility, enabling both the expansion and enhancement of this technology with every new specification release. Once products reach the market, the easiest way for consumers to learn which devices are compatible with other Bluetooth enabled devices is to visit the Bluetooth Gadget Guide.

Applications
With the availability of Bluetooth version 3.0 + HS, consumers can expect to move large data files of videos, music and photos between their own devices and the trusted devices of others, without the need for cables and wires. Some applications consumers will experience include:

• Wirelessly bulk synchronize music libraries between PC and music player or phone
• Bulk download photos to a printer or PC
• Send video files from camera or phone to computer or television

Availability

The Bluetooth SIG's formal adoption of the specification is only the first step in the product lifecycle. News out today from wireless chip manufacturers and Bluetooth SIG member companies Atheros, Broadcom and CSR shows the second step – getting silicon solutions to device manufacturers – is already underway. End products for consumers are expected to be in the market in 9 to 12 months.

Technical Specifications
This new specification release includes several major enhancements (learn more here - page requires member login):

• Generic Alternate MAC/PHY (AMP)
• 802.11 Protocol Adaptation Layer (PAL)
• Generic Test Methodology
• Enhanced Power Control
• Unicast Connectionless Data
