Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection.
Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.
Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.
Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.
If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.
Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.
The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.
Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.
if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.
If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.
If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

Microsoft wants to escalate the situation from Australia to the EU, what a surprise.
Hello all and welcome to another news article, this time we are focusing on Microsoft pushing the EU to accept law proposition from Australia.
For all of you who are not familiar with the given situation let me quickly explain. The feud began when the Australian government proposed a new law that targeted Facebook and Google specifically. The government said that it believed that both of the tech giants were using content from news outlets without paying.
Have you ever seen the little news snippets that Google or Facebook sometimes show its users to keep them up to date? These are lifted directly from news websites, and the Australian government claimed that this practice meant that people didn't bother visiting the news website. This then staved news websites of revenue.
As such, the government put forward a new law that would mean Google and Facebook would have to pay the source website for every time they displayed a news snippet. Facebook responded by removing its Australian news coverage in light of the law.
Google, however, put up a fight. It argued that its snippets encouraged people to click on it to read more, thus driving more traffic to the news website. It also said that such a law would be too expensive to maintain in the long run.
As such, Google threatened to remove itself from Australia if the law passed. This was likely a scare tactic, as 95 percent of Australian web users use Google; however, it actually opened the door for its rival, Microsoft.
Microsoft saw how it could push its own search engine BING to replace google. It of course went and reached the Australian government to assure them that BING is more than capable to fulfill its needs and fully abide by the proposed law.
Now Microsoft knows that if this law passes it could see a similar situation happening in Europe and it is pushing it. US News reported on how Microsoft plans to encourage EU countries to adopt this new law too. The company has teamed up with the European Publishers Council and News Media Europe to make the following statement:

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.
The number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.

In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.
Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.
Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.
After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.
Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.
“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error.
