drivers - Windows 10 - Bluetooth turned off and now can't be turned back on - "Bluetooth setting cannot be changed."

I have Bluetooth headphones, and they were out of battery so I disconnected them. When I tried to reconnect later, they refused, so I tried turning the bluetooth off and on in Windows. When I turned it off, however, the button to turn it back on disappeared:


enter image description here


Furthermore, the Bluetooth icon disappeared from the "hidden icons" in the task bar.


I went to the Start menu and tried using Cortana to turn it back on, I typed "turn on bluetooth" and after a few seconds it said "Bluetooth is connected", and then another second later it says "Bluetooth setting cannot be changed".


What is happening? How can I get my bluetooth toggle back? Should I try uninstalling the bluetooth driver and letting Windows reinstall it upon startup?


EDIT: After restarting my computer, the Bluetooth driver is entirely missing. I will try restarting my computer to see if it reinstalls.


EDIT 2: It did not reinstall.


EDIT 3: I attempted to install Intel's drivers but they did not show up in the driver's list. I then realized that there were "hidden drivers" and indeed, the original bluetooth drivers were hidden for some reason. All of them were up to date, but when I viewed their "properties" they displayed "Currently, this hardware device is not connected to the computer. (Code 45)". Should I uninstall them?


EDIT 4: As per Microsoft's suggestion, I uninstalled the device drivers and attempted to restart to reinstall them. Nope, no reinstall. My bluetooth drivers are just gone forever now.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
