One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

• Tap the Win + I keys to open Windows Settings.
• Next, select Devices from the menu and click on Bluetooth.
• After that, make sure that the toggle switch for Bluetooth is turned on.
• Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
• Then go back to the Bluetooth section and click on Bluetooth or other devices.
• From there, click on Add Bluetooth and select Surface Dial.
• Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

Hello and welcome to our Reasons to Defrag Hard Drive. You ought to defrag your hard drive, in case your PC is slow. This could enhance the efficiency and pace of your PC too as its hardware longevity. It places them where there is space, whenever your PC saves files. Often files are separated into bits. For example, whenever you remember a file and focus on it, it frequently doesn't fit back in exactly the same physical place. Where it can your PC divides up the file, occasionally into several parts, and saves it.

Why defrag?

Fragmentation causes difficulties that doing a defrag can correct. Fragmented files because it requires more resources and time to locate and remember these files slow down your pc. Applications may also take longer to load. Defragging can prolong the life span of the components. A defragged hard disk too can raise your likelihood of recovering lost information. Once fragmentation starts, it can propagate fast -- demanding defragging. It's like the pages of a publication are divided and hidden in several locations around a house, if a file is fragmented. It's like the pages of the book being brought back together, should you defrag. Defragging discovers all the bits of the file and places them in contiguous, actual places.

How will you defrag?

To defrag your hard drive, you must utilize software or utility. There are lots of defragging tools available. SpeedyPC Pro, a whole package of cleaning and optimization tools, can defragment your PC. Before you defrag, it's best to assess your hard drive. This evaluation finds if a defrag is needed and how much of the disc is fragmented. You simply allow the application do the work if it's determined that you must defrag your PC to enhance performance. To be able to defrag a drive, free disk space will be required by your PC. Defragging can take a while. How long depends on several variables, such as the system resources accessible, the disc volume, the number of files, and how fragmented the files are. It's a great idea to defrag when you don't have to use your pc or it isn't doing other jobs. For example, the night could become a great time to defrag. Be certain to close out of resource-intensive applications, like your antivirus scanner, before you defrag.
