According to security experts, it is most likely caused by the physical RAM which could be due to some error in the Realtek driver for Wireless USB 2.0 as well as corruption of the files inside the RAM, and so on.

If you are using a multi-monitor, then you might find it quite useful. It helps many users with their work and brings more productivity. And over the past few years, Windows has managed to offer one of the excellent multi-monitor features where users can plug in an additional monitor and access their work or use their computer seamlessly on both displays. This is really handy, especially for users who are graphic designers, gamers, and other professionals who have to use a larger screen for their work. One of the biggest inconveniences for users who use multi-monitor is that the Taskbar is switched on, on both displays, by default. This default arrangement is most likely to cause clutter on the second display. So if you are one of these users who find such a thing annoying, then you will find this post useful for you as we will walk you through how you can move the Taskbar to a second monitor. To get started, follow the instructions laid out below. Step 1: The first thing you have to do is right-click on the Taskbar. Step 2: Next, uncheck the “Lock the taskbar” option. Step 3: After that, click and hold the taskbar and drag it to the second monitor. Step 4: Once done, click the mouse button on the place where you want to place the taskbar. Step 5: Now right-click on the “Lock the taskbar” option to lock the taskbar. Once you’re done carrying out the steps given above, there are Advanced Options you can explore. This array of advanced options are offered by Windows 10 to fine-tune the multi-monitor experience of users. For instance, you have the option to choose to show the taskbar on an active screen only or combine the buttons on other taskbars. It would be better if you try out different variations and stick with the best one. In addition, you could also move the taskbar from one display to another.

It also offers step tracking, sleep tracking, automatic workout-tracking, active zone minutes, etc. It weighs 30g and has 1 inch grayscale OLED.

Amazfit Band 5

Amazon’s offering of fitness tracker is aimed at beginners and as such, it is lacking some advanced features including an automated working tracker or GPS, also the model does not have replaceable bands so customization is not an option. It does however offer activity and sleep tracking, heart rate monitoring and it is the only model that integrates with Alexa. The manufacturer states that the battery can last up to 15 days depending on usage which places Amazfit Band 5 as a device that has a longer life of use. The device itself is packed with a 1.1-inch color OLED and it weights 12g. It is splash-resistant, not water-resistant.

Xiaomi Mi Band 6

Xiaomi tracker is the best budget version on this list including in it 30 sport modes like running, cycling, yoga, swimming, and more.

The device itself is not very impressive, 7 days battery life with 0.7 inch OLED display and 17g weight packed with 50m water resistance is nothing spectacular, Samsung’s model is packing better hardware and way more battery life but all of the mentioned devices fall flat if we compare software to Garvin. Garvin’s Vivosmart 4 software is best on the list, it keeps track of your steps, sleep, calories burned, floors climbed, various exercises, and heart rate as standard features but you'll have advanced sleep tracking with REM sleep. It can also gauge blood oxygen saturation levels during the night with its wrist-based Pulse Ox sensor. In addition, a relaxation breathing timer complements the all-day stress tracking feature.
