Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.

Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.

So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:

Find and/or install the font that you wish to use

There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.

Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)

Create REG file

Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"=""
"Segoe UI Bold (TrueType)"=""
"Segoe UI Bold Italic (TrueType)"=""
"Segoe UI Italic (TrueType)"=""
"Segoe UI Light (TrueType)"=""
"Segoe UI Semibold (TrueType)"=""
"Segoe UI Symbol (TrueType)"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"="NEW-FONT"

All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".

Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG

Apply changes

Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.

Rolling back

If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"="segoeui.ttf"
"Segoe UI Black (TrueType)"="seguibl.ttf"
"Segoe UI Black Italic (TrueType)"="seguibli.ttf"
"Segoe UI Bold (TrueType)"="segoeuib.ttf"
"Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf"
"Segoe UI Emoji (TrueType)"="seguiemj.ttf"
"Segoe UI Historic (TrueType)"="seguihis.ttf"
"Segoe UI Italic (TrueType)"="segoeuii.ttf"
"Segoe UI Light (TrueType)"="segoeuil.ttf"
"Segoe UI Light Italic (TrueType)"="seguili.ttf"
"Segoe UI Semibold (TrueType)"="seguisb.ttf"
"Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf"
"Segoe UI Semilight (TrueType)"="segoeuisl.ttf"
"Segoe UI Semilight Italic (TrueType)"="seguisli.ttf"
"Segoe UI Symbol (TrueType)"="seguisym.ttf"
"Segoe MDL2 Assets (TrueType)"="segmdl2.ttf"
"Segoe Print (TrueType)"="segoepr.ttf"
"Segoe Print Bold (TrueType)"="segoeprb.ttf"
"Segoe Script (TrueType)"="segoesc.ttf"
"Segoe Script Bold (TrueType)"="segoescb.ttf"

In case you don’t know, Windows now comes with an all-new Light Mode theme which gives a light accent color to the Taskbar, Start, and Notification Area. Aside from that, it also brings new improvements and features. This new theme is somewhere between dark and completely white and in this post, you will be guided on how you can enable this new feature in your Windows 10 computer. Although the Light Mode sure looks stunning and a lot of users love it, it actually switches all the apps plus the Taskbar and Start Menu to the light mode which was not the case before. In addition, the icons in the system tray area, as well as the notification center, are also inverted. To resolve that, there are several ways you can customize the light mode theme as well as activate it in the Windows 10 v1903. How? Refer to each one of the options given below.

Option 1 – Via Theme settings

Windows 10 brought a new theme called “Windows (Light)” which will enable the light mode automatically and will set the accent colors to automatic. This will also apply the new Windows 10 wallpaper on your desktop. To enable Windows (Light), all you have to do is right-click on the desktop and select Themes from the left menu. After that, select the Windows (Light) option under the Change Themes section. This will apply to the Windows (Light) mode.

Option 2 – Via Color settings

The second and more customizable way to activate the light mode is via Settings. Aside from the Light and Dark, Windows also introduced a Custom color option which allows you to decide the default Windows and App mode independently. To enable Light mode via Settings, refer to the steps below.

• First, open Settings and go to Personalization.
• After that, select “Colours” from the left menu.
• Next, select Light under the “Choose your color” section to activate the light mode in Windows 10. This will activate light mode all over your computer.

Note: If after activating light mode, you find that you don’t like it and you want to keep things as they were before (Light App Mode and Dark Windows Mode), you can achieve that using the Custom option. All you have to do is select Custom from the drop-down menu to decide the default Windows and app mode independently. After that, select light under the default app mode and dark under the default Windows mode so that you can keep things as they were before the update. On the other hand, you can also try the opposite version of the light Windows mode and Dark app mode since Windows increased the level of customizability which allows users to use an option of a completely light mode.

There are cases when your Windows 10 PC can encounter an issue where it gets stuck and will display a message that says, “Preparing Security Options”. If this is happening to your Windows 10 PC, you won’t be able to use your keyboard or even mouse and your screen will only be stuck on the screen as mentioned above. As your computer is still stuck, you will be left with no choice but to shut it down and restart it. Tap the F11 key as soon as your PC powers on. This will take you to the Advanced Startup options where you can carry out some steps. If it still didn’t work, you have to boot your Windows 10 PC into Safe Mode and then try out the troubleshooting options below.

Universal PnP or plug-and-play monitors use a generic PnP Windows driver. Whenever a user plugs a USB device or monitor into a PC the system will automatically identify the device and it will install the proper driver for smooth running. Generic PnP Monitor in Windows 10 means that Windows 10 installed a monitor driver as the PNP did not recognize the device. This generic PnP monitor driver may not work perfectly like the manufacturer’s one. It can lead to issues like unable to set the best monitor resolution and the screen refresh rate. Therefore, it is important to fix this issue. All of that being said let us fix your PnP display driver issue.

1. Reconnect monitor

   Always try this first, just by unplugging the monitor and then plugging it back may resolve the issue, if the monitor was not detected properly the first time, there are very high chances that this method will resolve the issue.

2. Check if the Device Manager is reporting an error and update the driver

   If the hardware is functioning properly then the issue might be in Windows not detecting device or driver malfunction. In any case, the Device Manager will be the one who will report this problem. In order to check to see if the driver is properly working press ⊞ WINDOWS + X to open the hidden start menu. Once it opens, click on Device Manager to open it, If you have a driver device error inside Windows, you should see it immediately when entering the Device Manager, it will have a yellow exclamation mark beside it. Right-click on it and choose update driver.

3. Reinstall driver

   If driver update failed or you already have the latest drivers, reinstalling them could fix the issue since drivers might have corrupted during installation of some update or application. Follow steps from point 3 to get to the driver in Device Manager, then right-click on it but instead of update choose to uninstall. Reboot Windows once the driver is uninstalled and Windows will install a new one automatically. If you do not want to update drivers automatically install the latest driver for your device, then reboot.

4. Check Windows update

   Check to see if the latest Windows update is installed, update your Windows if needed

5. Fix driver issue with DRIVERFIX

   If everything else fails, get DRIVERFIX, a premium solution for your PC issues, and fix driver errors.

Same as in previous Windows versions, Windows 11 will also use certain applications as default ones for opening certain file types and file extensions. And yes, same as in previous versions it will come preconfigured for certain file types and associated applications like for example photos for pictures. Of course, users usually have their own favorite applications for certain file types and much more prefer to open them inside the application of their choice instead of the default one. We can change the default application like in previous Windows versions but this time there are two ways and overall more control of this process. Windows 11 has settings for choosing default file type applications and default file extension applications giving you more control of this process.

The opening setting for apps

Whatever you wish to change default application or default extension application you will need to open settings for default application. Follow steps to quickly go into it.

1. Press ⊞ WINDOWS + I to open settings
2. Select Apps on left
3. On the right part select Default Apps

Now you are in settings for choosing default applications

Choosing default application by file type extension

This is considering by Microsoft as a typical way to set default applications inside Windows 11. Once you are inside the settings app there is a box labeled Enter a file type or link type. Inside the search box, type in file extension that you wish to associate the application with like .JPG, .TXT, or other. If the file extension is not associated with any application you will be presented with a Choose a Default button, if however, the file extension is already associated with the app, you will need to click on the app box itself. In any case, a pop-up will appear and ask How do you want to open YOUR FILE EXTENSION files from now on? Choose Application from the list of presented ones and click on OK.

Choosing default file type

Another method is to select the default application by file type selecting application for it. In the settings screen, under the search box, you will have a list of installed applications. Choose the application that you would like to associate a file type with and click on it. On the next details screen scroll down and select the file type that you want to associate with the selected application and click on OK.

Other/third method

There is also the third method for choosing the default application for file type but it includes some surfing on your hard drive and it can be more time-consuming for first-time settings. But it is fairly quick when you need to only use it once on some new file type (for example you have a new application installed and want to switch just one file type extension to that application). Locate the file that you want to associate with the application and right-click on it. Select Open With from the menu and then Choose Another App. Pop up will appear, select the application that you would like to use, and check the box beside Always use this app to open CHOOSEN EXTENSION files followed by clicking on the OK button.

Microsoft just released Windows 11 ISo file, based on the latest Insider Preview Build 22000.132. Inside build, you can try all-new features like clock updated app, snip tool, and everything releases so far via various patches. You can also use Windows 11 ISO file to do a clean install on your computer, but if you go with this option all of your existing files will be deleted. Microsoft says it added the ability to name your PC during the setup experience. You’ll also get to experience the Get Started app that’s designed to help you get going on your new Windows 11 PC (even if it’s not actually a new one).

Download ISO

• Go to the Windows Insider Downloads page. You will need to sign in with a Microsoft account registered with the Insider Program.
• Scroll down to Select Edition and select the build you want to download. You will most likely want the one at the top from the developer channel, as this is where Windows 11 should arrive first. So far, only Windows 10 builds are available. Click confirm.
• Select your preferred language. Not all languages ​​available for Windows are compatible with the Insider program, so you may have to stop depending on where you are from.
• Click the download button and the ISO file will start downloading.
• This is definitely an easier method, but unfortunately, it is not available yet. We will update this article once Windows Insider ISOs are available. Later, once Windows 11 64 bit is available to everyone, you can also download the stable build of Windows 11 iso. Microsoft offers the Media Creation Tool and Upgrade Assistant, which usually do just that. It will be some time before Windows 11 versions of the tools are available, as the operating system is only getting closer to this holiday.

Upgrading your Windows 10 computer does not always go smoothly and you often encounter not just one but various errors so, in this post, we are going to cover several Windows 10 upgrade errors such as 80240020, 8007002C, 80246007, 80070004. All these upgrade errors are related to the Windows Update folder. Thus, you need to clear the Software Distribution folder, repair the System Image and fix System Health in order to resolve all these Windows 10 Upgrade errors. Before you get started on the steps to resolve these tons of errors, you have to disable your security program for the meantime, disconnect your peripherals, remove USBs connected to your PC and then make sure that your PC is connected to the main power supply. Once you have everything covered, carefully follow the options given below.

Option 1 – Delete Windows 10 Update Files in the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, go to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

• Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.

Option 2 – Try using the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • 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.

Note: If it happens that the Windows Update client is broken, you need to run the following command to repair it then restart your PC and click on Update once again.

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Note: The Windows Upgrade error, with error code 80240020 is an expected error message that happens when the upgrade requires customer user action. Thus, you need to do the following steps to resolve this particular Windows Upgrade error.

• Tap the Win + R keys to open the Run dialog box.
• Then type “regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdate
• Now right click on WindowsUpdate located in the left pane and then create a new key and name it as “OSUpgrade”
• Next, right-click in an empty space in the left pane and create a new DWORD and name it “AllowOSUpgrade” and enter “1” as its value.

Option 3 – Try running the Windows Update in a Clean Boot State.

Putting your PC in a Clean Boot state can also help you install Windows Updates or Upgrades without any trouble because, during this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After that, try to install the Windows Updates or upgrade again.

The Stop error might have something to do with an issue related to IRQ. You can verify it by switching your PCI Cards around. Aside from that, you can also check if the IRQ2 is assigned to a COM Port that is unavailable at that time.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like MUP_FILE_SYSTEM. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 7 – Perform a System Restore

Performing System Restore might help you in fixing the Blue Screen error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
