So in that spirit, we will continue in this article reviewing some of the best fitness trackers that can be found in the time of writing this article in 2021. Now the market for fitness trackers is not small by any means and offerings are also not small, from no-name manufacturers costing only a few bucks to more serious one’s going slightly over 100 USD there is a fitness tracker for everyone. In this particular article, we will not focus on cheap few dollars no-name ones, instead, we will be offering top ones in the field among some in the middle range simply because we can stand behind them considering quality and precision.

Fitbit Charge 4 fitness and activity tracker

Fitbit is not a pioneer company in the world of fitness trackers and it shows. Charge 4 model offers maybe the best quality, performance, and features for its price. It stands out with implemented GPS meaning that you will need your phone for tracking workouts. It also offers step tracking, sleep tracking, automatic workout-tracking, active zone minutes, etc. It weighs 30g and has 1 inch grayscale OLED. Battery life is said to hold up to 4 days if you use built-in GPS regularly, if you decide to use GPS constantly device will last only 5 hours. Without GPS it can last up to 7 days and it is water-resistant and waterproof up to 50 meters.

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. Battery life is not bad also packing up to 14 days of life but only if the device is not used constantly. It has activity and sleep tracking, a heart rate monitor, sleep tracking, customizable replicable bands and it is water-resistant up to 50m. It comes in a 1.56 inch AMOLED color display and it weighs 63g. The device also has menstrual health tracking making it a great device for women.

Samsung Galaxy Fit 2 fitness tracker

Now we are getting into serious and little more expensive ones. Galaxy Fit 2 is among the top-notch trackers currently on the market. It of course can work along with Samsung’s smartwatches and mobile phones. Packed in the military-grade 1.1-inch casing with color AMOLED and weighing 91g with battery life up to 21 days and water resistance up to 50m this bracelet is an absolute beast. It comes packed with features from standard sleep tracking to automated workout-tracking but it also has a connection to Samsung’s Health mobile app to choose from over 90 workouts, it monitors heart rate and stress levels making it really one of the complete solutions for serious fitness enthusiasts.

Garmin Vivosmart 4 fitness tracker

Last on our list is Garmin vivosmart 4. 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. Lastly, the "Body Battery" monitor helps optimize your daily activities based on your energy levels making it truly the only complete tracking solution on this list.

A lot of Windows users, use a second GPU for their computer systems, especially gamers above the dedicated graphics card. The operating system is set such that the dedicated high-end graphics card is set to default but there are times when the system does not recognize or detect the second graphics card. Even though every computer system comes with an integrated graphics card, for the most part, it is insufficient for graphics-intensive games and software which is why if you have an extra dedicated graphics card and your computer does not seem to detect or recognize it, then this post is for you. It could be that the dedicated graphics card has failed or it could also be an issue with the drivers and so on. Follow the suggested options below to resolve the problem.

Option 1 – Update your Graphics drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.

Option 2 – Update the BIOS

Take note that you have to be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.

• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 3 – Try changing the GPU settings

• Right-click on any empty space on your Desktop and select Graphics Properties. Note that the Graphics Properties screen depends on the graphics drivers installed on your computer and are system-specific as they may be different for other systems but they aren’t hard to find.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Taking information from the internet or from other sources usually involves selecting the text, copying it into the clipboard, and then pasting it into your file. In today's modern applications pasting text will most of the time take its formating with it.

By formatting what I am talking about are parameters like font size, line breaks, hyperlinks, font styles, etc. and sometimes you do not want any of these in your file, you would like and prefer to have just plain text so you can format it as you wish.

In order to paste just plain text instead of using the CTRL + V keyboard shortcut, press CTRL + SHIFT + V instead. This shortcut will paste the only text into your file.

Shortcut and Microsoft Word

Leave it to Microsoft to make its shortcut not work in their application. In Microsoft Word, you can only use the standard CTRL + V shortcut, if you press CTRL + SHIFT + V nothing will happen. So in order to paste the only text into a word document, choose to paste special > text only

Other applications

I have tried CTRL + SHIFT + V in various applications like photoshop, illustrator, InDesign, visual studio code, slack, discord, WordPress installations, etc and only one that has not worked for me was Word and office in general so you are safe to use this trick and have desired results.

Error Code 48 – What is it?

Error Code 48 is a device driver error code that users can encounter on any Windows 2000 operating system and later versions.

It occurs when the connected peripheral device cannot be run as the Windows operating system’s driver required to install the programs for peripheral devices has either been corrupted or is incompatible with the system.

It prompts the user with the following message on the screen:

The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

Solution

Error Causes

Like most other Windows error codes, error code 48 is triggered by the following factors.

• Corrupted system registry files
• Presence of viruses in the device
• The device driver is out-of-date

If this error code is not rectified, it could give birth to other driver device errors such as error code 52.

Further Information and Manual Repair

Method 1 – Run a complete scan for malware and spyware

Identifying and removing the viruses in the system registry and in the connected devices is the easiest method to fix the corrupted registry files.

Viruses such as spyware and malware infect the registry entries and eat up the files that lead to incomplete or missing data. This creates problems for installing external devices as the driver required to install them is not complete.

Method 2 – Use System Restore

You can also use system restore to eliminate the problem. Here is how you can use it:

• Log in using an Administrator account
• Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
• Click ‘Restore my computer to an earlier time’ and click ‘Next’
• Select the last Windows to restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
• Click ‘Next’ on the confirmation window to proceed
• Restart your PC after restoration is complete

By restoring the system via the last saved system checkpoint, you can obtain undamaged Windows system registry files that can help resolve the error code.

Method 3 – Manually uninstall and reinstall the device driver

Since Error Code 48 is due to a missing or an out-of-date device driver, uninstalling and then reinstalling the device driver can help solve the error.

You can do this by firstly logging in as Administrator and opening Device Manager. Select the device that is causing the problem and double click it; make sure that the peripheral is connected properly to the PC.

Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’. Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

• Once you’ve entered all the commands given above, they will stop all the Windows Update services that are running on your computer as well as clear the SoftwareDistribution folder, and reset the Catroot2 folder. Now you have to start all these Windows Update services you’ve just stopped by executing the following commands:
  • net start wuauserv
  • net start bits
  • net start appidsvc
  • net start cryptsvc
• After that, restart your computer and try to run the setup again, and see if the error is now fixed.
