Guide to Repair Error 0x80040116

As you know, all computer mouse devices are designed ergonomically for users who are right-handed. Although that’s mostly the case, there are also other mouse devices that are designed specifically for left-handed users or the ones that can be used by either the right or left hand. But before you look for these kinds of mouse devices, there is actually an option you can try so that your mouse device can work with either the left or right hand. All you have to do is configure your mouse device. Aside from setting the device to work on either hand, you can also switch mouse buttons, from left to right, using only a couple of simple steps. As mentioned earlier, most mouse devices are created for right-handed users. Meaning to say, these mouse devices are configured to be right-handed with their primary button on the left and the second one on the right. The primary button is used for certain functions such as selecting and dragging. Now you can configure your mouse to be left-handed by swapping its predefined functionality. How? Refer to each one of the given instructions below.

Option 1 – via Control Panel

• First, go to the Start Menu and search for “control panel” in the Start search.
• Once you see it from the search results, click on it to open it and then go to the Hardware and Sound section.
• From there, click on Mouse under the Device and Printers section. This will open the window for Mouse Properties.
• Now you have to check the Switch primary and secondary buttons box.
• Then click on OK to save the changes made. After that, your primary select button on your mouse device is your right button while the secondary button, also known as right-click, is now the left button.

Option 2 – via Windows 10 Settings

This is the second option you can check out to change the configuration of your mouse from being right-handed to being left-handed.

• First, right-click on the Windows icon and select Search.
• Next, type “mouse” and from the search results that appear, click on Mouse Settings.
• After that, select “Right” from the “Select your primary button” drop-down menu. This should set the mouse device from being right-handed to being left-handed.

Windows 11 has brought some bad reviews for its inability to change the taskbar location to the screen. Luckily we can still hide it if needed. In order to hide the taskbar from the screen follow these simple instructions:

1. Right-click the taskbar itself and select “Taskbar Settings” in the tiny menu that pops up or open Windows Settings and navigate to Personalization > Taskbar
2. Click on Taskbar Behaviors
3. Check the box next to Automatically hide the Taskbar
4. Close settings

As soon as you click on the box to hide the taskbar Windows 11 will apply your settings and hide the taskbar, you will get one line at the very bottom of the screen indicating that the taskbar is still present, just hidden. When you reach the bottom of your screen with the mouse it will pop up and be visible again, just like in all Windows so far.

When you get this kind of error while trying to upgrade your computer, although there could be various reasons for this, the primary one is that when you upgrade from one update to another, something stopped the upgrade process to migrate the user data. To fix this error, you can try to run both the DISM tool and the System File Checker to automatically repair any corrupted system files. You could also try checking the free storage space of your primary drive and if you have any file lock apps like BitLocker, consider disabling them for they could also be the reason why you’re getting the error.

Option 1 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10 which might be the reason behind the Windows Upgrade error 0x80070003 – 0x2000D. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt as admin.
• Then type in this command: exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Once it’s done, restart your computer and then check if the issue is resolved or not on the next startup.

Option 2 – Run the SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the Windows Upgrade error to appear. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your PC.

Option 3 – Try checking the free storage space on your primary drive

The next option you can try to resolve the error is to see if you have enough free storage space on the primary drive because if you don’t then it’s probably the reason why you’re getting this error. To fix it, you need to free up some storage space by following these steps:

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.

• Windows Upgrade Log Files
• System created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Note: Once you’re done freeing up space on your drive, try to run the setup file again.

Option 4 – Try disabling BitLocker and other file lock apps

If you are using BitLocker or other file lock apps, then it could be the reason why you’re getting the error. Usually, file lock apps don’t cause any kind of issue, however, if you have something that works on file level like BitLocker, you can try to disable it. Once you’ve disabled it, try to install the Windows 10 Upgrade again and after you do, enable BitLocker again. This should fix the problem.

Having the latest applications is often preferred for most users but sometimes we have some old applications which have not been updated or simply we just want to run oldie on our computer because it does everything we need and we do not want to upgrade in order to save some money. The issue is presented sometimes when we try to run an old application in Windows 10 and some components are missing in Windows itself or the application is simply coded in a way to work on older Windows versions. If by any chance you have this issue then this guide is for you since we are going to show you how to run old applications in Windows 10. This guide is made in a way to takes into account that the application itself is completely installed on your Windows 10 machine if you can not even install the application you will need to search solution for that particular application since that can not really be generalized and pinpointed issue, every application is different.

Running old applications using the compatibility option

All of that being said, let's start that old app you have. First thing is to locate an executable file or shortcut of the desired application. Once it is located, right-click on it to bring up the menu, and all the way to the bottom you will find properties. Left-click on properties. The application settings screen will open, in upper tabs locate Compatibility and left-click on it. After the click, you will find yourself in application compatibility settings. In this window, you will face different options to run the chosen application in various modes in order to make it run. How settings are self-explanatory and different applications will need different settings sadly we can not cover them all but your safest bet is to run them in an environment where they have worked. For example, if the application was working fine in Windows XP and required administrator privileges, check Run this program as an administrator and Run this program in compatibility mode for Windows XP.
