During Windows 10 installation, you will see all the beautiful user interfaces, however, what’s more, important are the drivers, your processor, and free storage disk in order for the installation to be successfully completed. So if you are getting the CompareExchange128 error during the installation of Windows 10, this means that the CPU lacks a very important instruction known as “CMPXCHG16B”. Thus, if you don’t have CMPXCHG16B, then it will result in the CompareExchange128 error when you install Windows 10. In fact, CMPXCHG16B, PrefetchW as well as LAHF/SAHF is a criterion for you to be able to use Windows 10 64-bit version when upgrading from an earlier version of Windows. So what exactly is the CMPXCHG16B instruction? The CMPXCHG16B instruction is the one that performs an atomic compare-and-exchange on 16-byte values. This instruction can also be referred to as “CompareExchange128”. The atomic compare-and-exchange means that the CPU compares the contents of a memory location with a given value. So if the values are the same, it modifies the contents of that memory location to a new given value. Note that this kind of issue only happens to the 64-bit Windows 10 version and the only way to resolve it is by getting an update on the hardware level from the OEM. On the other hand, if nothing really works, it’s maybe time for you to get a new CPU but before you resort to that, in the meantime, you can try following the options given below to fix the CompareExchange128 error during the installation of Windows 10.

Option 1 – Try to update the BIOS and Chipset Drivers

One of the best things you can do to fix the CompareExchange128 error is by updating the BIOS and chipset drivers which is why you need to check if your OEM has an update available for your computer’s BIOS as well as the related chipset drivers. But before that, you need to first check the BIOS version. To do so, follow these steps:

• Type “msinfo32” in the search bar and hit Enter to open the System Information Tools.
• After opening the System Information Tools, check the BIOS version.
• Then take note of that BIOS version. You also need to use the BIOS utility that came with your computer and use it for the upgrade. Note that it is different for every computer and if you don’t have it, you can just go to the OEM website and see if there is an option to download it there.

Option 2 – Try to downgrade to the 32-bit Windows 10 version

If option 1 didn’t work as the BIOS update is not available, you can also try downgrading to the 32-bit version of Windows 10. Keep in mind that this will bring restrictions on the amount of RAM installed and other places but that won’t be a problem as you can still switch.

Option 3 – Try buying a new hardware

If none of the first two options didn’t work for some reason then maybe it’s time for you to purchase new hardware especially if your computer is way too old. In such cases, it’s better to buy new hardware or better yet, a new computer that can keep up for the next couple of years.

If you have a dual monitor setup on your Windows 10 computer and you mostly use the second screen when you are presenting something, this makes the Taskbar completely unnecessary and is not really required. So if you are using your computer generally and do not want the taskbar on your second screen, read on as this post will guide you in disabling Taskbar on your second display. The good thing is, Windows comes with a built-in feature to disable Taskbar on your second screen or projector connected to your computer. In this post, you will be guided on how you can hide or disable the Taskbar from the second monitor in Windows 10. This post is coming in handy especially if you are using projectors or multiple displays. Refer to the steps given below to disable Taskbar on the second display in Windows 10. Step 1: Go to Settings and click on Taskbar from the left menu. Step 2: After that, scroll down to lo look for Multiple Displays. Step 3: Next, turn off the toggle labeled, “Show taskbar on all displays”. Note: After completing the steps given above, it will disable the Taskbar on all the secondary displays. Bear in mind that these settings will work only if you are running a second screen in Extended mode. Contrariwise, if you are in the Duplicate mode, this setting will not work but you can always set your Taskbar to Autohide so that it won’t be displayed.

On the other hand, if you are facing some issues in finding which screen is primary and which one is secondary, refer to these steps:

Step 1: Go to Settings and select System. Step 2: Next, from the left menu open Display. Step 3: From there, select the desired display and make it the primary one as required by your setup.

In this post, you will be guided on how you can set up the USB tethering feature on your Windows 10 computer and share your mobile device’s mobile data so other devices can also access the internet. Tethering is usually known as Wi-Fi tethering which allows users to share mobile data to any device with Wi-Fi, laptops included. This is really useful especially when you have no other way to access the internet. For instance, if you are using a desktop computer and there is no way for you to connect to the Ethernet, and you have no Wi-Fi adapter that you can use to connect to a router as well, you can use USB tethering instead to access the internet. It is almost similar to Wi-Fi tethering except that it works over a USB connection instead of a Wi-Fi adapter. USB tethering is almost quite the same as an Ethernet connection except that it’s faster compared to Wi-Fi tethering as well as Bluetooth tethering. Just like Wi-Fi tethering, USB tethering is free unless your network carrier has blocked it. Thus, it’s better if you make that clear with your operator. Once you have that covered,

Follow the instructions provided below to set up USB tethering on your Windows 10 computer.

Step 1: First, connect your mobile device to your Windows 10 computer using a USB cable. Step 2: If it asks you to enable the file transfer feature, just cancel it. A prompt that says, “Tethering or Hotspot active—Tap to setup” should be available as soon as you get connected – tap on it. Note: If there is no prompt, just go to Settings > Network and Internet > Hotspot and Tethering and from there, toggle on the USB tethering option. Step 3: Afterwards, the setup will create a new network adapter in Windows 10 automatically and your computer should now be connected to the internet using USB tethering. Note: You have to make sure that the Wi-Fi connection in your mobile device is turned off and if it is connected to an existing network, the USB tethering will be disabled but if you see its status as enabled, then the USB tethering setup is successfully done. In addition, keep in mind that the location of tethering can be different for every phone, especially on a customized operating system such as RealMe, Redmi, Samsung, and any other mobile device although they are clubbed in the section of Mobile and Data Network. In case you encounter some problems when using USB tethering in your Windows 10 computer, there are troubleshooting tips you should follow. The NDIS-based Internet Sharing Device network adapter is what Windows 10 uses to make USB tethering possible so if it stops working, follow the options provided below.

Option 1 – Perform basic check

The first thing you can do if you encounter problems in USB tethering is to do a basic check like checking if Wi-Fi is enabled automatically as well as check if the USB cable is disconnected or if you’ve turned off USB tethering accidentally.

Option 2 – Try installing or updating the USB RNDIS adapter

RNDIS or Remote Network Driver Interface Specification can also help you resolve any USB tethering problem.
