It offers the option to create custom keyboard shortcuts that allow users to launch apps, and even websites, instantly. There are already tons of keyboard shortcuts that are built-in in Windows 10 but in case you don’t know, you can actually create new ones. Doing so is not a difficult task and in this post, you will be guided on how you can exactly create custom keyboard shortcuts in your Windows 10 computer. Most users would create desktop shortcuts or pin the apps in the taskbar to speed up the process of working on their computers. It is an easy task to do since you can easily do it by dragging an app from the Start Menu to the desktop or by simply right-clicking on the executable app and selecting the “Create Shortcut” option. However, doing so would take physical effort and there are times when you have to minimize all the apps to get to the desktop so you can click the shortcut and this is where the Custom Keyboard Shortcuts come in handy. You can create Custom Keyboard Shortcuts in Windows 10 for various programs – from the traditional desktop apps to the new universal apps – you can fling in a shortcut so that you can instantly open them faster compared to when doing it manually and besides this also wouldn’t affect any of the ongoing system activity. To get started, you need to follow the steps provided below carefully.

To add Custom Keyboard hotkeys to a program and website desktop shortcuts, here’s what you have to do:

Step 1: First, you have to right-click on the app or website and select Properties. Step 2: After that, go to the Shortcut tab and from there, you will see the “Shortcut key” textbox which allows you to enter a new or custom keyboard shortcut for the app or website. Step 3: In the textbox field, input your preferred letters to set up the new hotkey. Keep in mind that this custom shortcut has to be combined with the Ctrl + Alt keys which means that if you want to select “N”, you have to tap the Ctrl + Alt + N keys. Step 4: Once done, click on the Apply and OK buttons to save the changes made and then close the window. Step 5: After that, tap the newly created keyboard shortcut, Ctrl + Alt + N keys again to open the app or website you’ve set up earlier.

• Step One: Open the Start Panel and select “Control Panel.”
• Step Two: Find the setting for “Clock, Language, and Region” and choose “Region and Language.”
• Step Three: Select the option for “Keyboards and Languages,” then under the settings for “Display language,” choose “install/uninstall languages” and select “uninstall display languages.”
• Step Four: For any languages that you do not wish to keep, deselect them and choose “Next.” It may require several minutes for the process to complete.
• Step Five: After the unwanted language packs have been removed from your computer, you can attempt to run Windows Update again. You may want to restart your computer first for maximum efficiency.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

The standard icon place in the Taskbar inside Windows 11 is in the center. Some users welcomed this change, some not so much. If you are part of the user base that is not so much thrilled with this Microsoft’s idea of innovation, do not worry, there is an easy way to move all icons and start button on the left inside Taskbar.

Moving icons in Taskbar

1. Open Windows settings by using ⊞ WINDOWS + I key combination
2. Click on Personalization
3. Select Taskbar
4. Click on Taskbar Behaviors
5. Click on the drop-down menu beside Taskbar Alignment
6. Select your desired option of icon alignment
7. Close settings

Your options will be active right away and you will see icons switching to the position of your choosing.

Windows 10 and Windows 11 have automatic dynamic screen brightness depending on the surrounding light inside the room. Please take note that this option is available only on devices with build-in screens like laptops, tablets, and all in one desktop PC. If you are connected with your PC via an external monitor you will not have these settings available and probably feature is not even working.

Some computers will also allow automatic brightness changes also on what is displayed on the screen. This option is meant to save battery life on devices. Microsoft calls this automatic brightness feature Content adaptive brightness control. In order to change this setting, we will go to settings inside Windows.

Disabling automatic brightness inside Windows

Open Settings inside Windows, in Windows 11 press WINDOWS + I to open settings, then click on the system in the sidebar and then go to Display. Click on the small arrow beside the Brightness slider in order to expand a small menu and then uncheck Help improve battery by optimizing the content show and brightness.

Inside Windows 10, go to Settings and then go to System and then in Display under the Brightness and Color section look below and locate the box that says Automatically adjust contrast based on the displayed content to help improve battery and uncheck it, if the box below with text Change brightness automatically when lighting changes exists, uncheck it as well. Close settings and you are done.

Computer crashes are one of the most annoying things that can happen to users. It often loses your data and work, you must spend extra time if you were in the middle of something and can even break Windows itself. Before we move to the article I just want to say that technically there are no random crashes, there is always a reason why the system hangs up, why you received blue screen, annoying restarts out of nowhere and many more PC crashes. In this article, we will explore many possible reasons why something may occur and offer you straight forward solution on how to escape the situation and prevent it from happening again. Without further delay, let's begin:

1. Check switch connectors and power outlets

   Yes, sometimes the most basic approach provides the best results, check to see if your power outlet is stable and providing you with constant voltage, if not, maybe you want to invest in a UPS system so you do not face random shutdowns and restarts during work, also while you are at it, check to see if that reset and power switch are connected properly and that they are not dirty or loose.

2. Clean your PC and check connectors

   Dirt can cause many issues with computers, from overheating to shutdowns to blue screens and memory dumps, check to see if your computer is clean enough and that all connectors are connected tight into their respective sockets.

3. Check the temperature of your CPU

   CPU overheating can cause so-called random freezes and blue screens, the computer might shut down or restart also without any visible reason. Check to see if your fan on the CPU is working properly and change the thermal paste if needed.

4. Check the health of your hard drive

   If your hard drive is beginning to go down the path of dying out, many issues can come from this condition. There are many tools on the internet and in Windows itself to check if your hard drive is working properly.

5. Run antivirus and firewall

   Random lock-ups or similar issues can also occur if by any chance you have some malware on your system, run protection software, and keep it updated to make sure the issue does not come from the computer being infected with malicious applications.

6. Keep system clean

   Have a habit to clean regularly system files and registries, keep removing unnecessary files from your computer and regularly update your Windows and applications along with drivers.

7. Run memory test

   Bad RAM bank can cause many issues during the work, check it out to be sure the problem is not RAM itself.

8. Do not run applications that are too demanding for your system

   Some applications require stronger hardware, and some require the latest hardware, if your computer is a little outdated, running a demanding application can cause issues like freezing, restarts, etc.

9. Remove applications you do not use

   This does not seem like anything important but if you are not using a specific application just remove it from the system, why? Sometimes an application has some ties to certain services and if it is outdated can cause issues for newer ones.

10. Stop installing everything you find on the internet

    Yes, that extension for chrome looks cool, yes, that fancy new player seems sick but if it is from an unverified source and from the unknown publisher without any reviews maybe you are better off with it. You can never tell what you might be placing into your system from the internet.

And that's it, 10 reasons and solutions on what to do on random computer freezes, crashes, etc.

One of the useful things you can use on your laptop is touchpads. They help users in achieving tasks through the gestures and multi-finger tap or touch support it brings in the scope for various shortcuts. However, not all times touchpad brings productivity as it can also encounter some issue every now and then. One of these issues has been reported on a couple of Lenovo laptops that use touchpad drivers from the Alps Pointing Device. According to the reports, an error saying, “Set user settings to driver failed” when they use the touchpad. This type of error on the touchpad usually occurs when a computer boots up and it could be caused by a faulty update on the Alps pointing device driver which is being installed in the background. To fix this error on the touchpad, you could try to disable the Alps pointing device entry from the MSConfig or you could try to get the latest version of the driver or uninstall the driver altogether. Before you proceed with the troubleshooting tips given below, make sure that you create a System Restore point first. Once you have that covered, proceed to the following options.

Option 2 – Try to download and install the latest version of the driver

The next option you can check out to fix the error is to download and install the latest version of the driver from the official website of Lenovo support. Note that an updated version of the touchpad driver will most likely get rid of the error. However, you have to make sure that the version you’re going to get is compatible with your existing Windows version.

Option 3 – Try to uninstall the Alps Pointing device driver

If the first two given options didn’t work, you can try uninstalling the Alps Pointing-device driver instead. You can do this under the Mice and other pointing devices section. After you uninstall the driver, restart your computer and delete the driver’s leftover folder inside this location in File Explorer (C:/Program Files). Once you’re done, restart your computer and check if the error is now gone. Keep in mind that after you’ve uninstalled the driver, any extra configuration features that Lenovo drivers offered before the uninstallation will no longer be available.
