Windows Clock is missing, invisible or black

The Adaptive Brightness setting in Windows 10 is a useful setting you can use in adjusting your computer’s brightness. It helps you get the brightness automatically based on the light around your computer. However, there are times when it does not work or it doesn’t turn off when you want it to. If this issue happened right after you update or install Windows 10, then read on as this post will give you a couple of options you can try to resolve the problem.

Option 1 – Try to run the Power Troubleshooter

The first thing you can do to resolve the issue with Adaptive Brightness is to run the Power Troubleshooter as the problem could occur due to some conflicted power settings. To use it, refer to the following steps:

• Open the Windows 10 Settings panel and go to Update & Security and then to Troubleshoot.
• After that, scroll down to your left-hand side and click the Power option.
• From there, you should see the “Run the troubleshooter” button. Click on it to fix the problem.
• Afterward, follow the next on-screen instructions that follow.

Option 2 – Try disabling or turning off the corresponding options in GPU settings

The problem might be due to the Graphics card settings. If you are using either an AMD graphics card or the HD graphics of Intel, you may have to disable the power-related options in the GPU settings. To be specific, you have to disable the Vari-Bright in AMD graphics card settings or the Display Power Saving Technology under Intel’s Graphics panel.

• AMD users:
  • Open the AMD Radeon settings panel.
  • Then go to Preferences. From there, select Radeon Additional Settings.
  • Next, go to the Power tab and click the PowerPlay option.
  • You should find an option called “Enable Vari-Bright” located on your right-hand side. Remove the mark from its checkbox and then save the changes you’ve made.
• Intel users:
  • Open the Intel Graphics and Media Control Panel from your Desktop.
  • Then select the Basic mode and go to the Power tab.
  • From there, select “On battery” as Power Source and then you’ll get the Display Power Saving Technology option. It should be set to enabled by default.
  • Now remove the mark from the checkbox and then save the changes you’ve made.

Option 3 – Try resetting the Power Plan defaults

You might also want to use a command-line tool to resolve the problem. This command-line tool is known as PowerCfg. It is a command utility tool that will scan your computer for 60 seconds to know its power. This tool gives detailed results in the form of an HTML report that will help you in evaluating the real cause of the battery drain issues. You can also use this tool to reset the Power Plan defaults of your computer. To use it, follow the steps below.

• Open the Command Prompt as administrator.
• Then type in the following command and tap Enter to execute it:

powercfg –restoredefaultschemes

• After the command has been executed, restart your computer.

Option 4 – Try updating your Graphics drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 5 – Try disabling adaptive brightness via Registry Editor

Since you will be dealing with Registry files in this post, you need to create a System Restore point first. Once you have that covered, proceed to the following steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREIntelDisplayigfxcuiprofilesMediaBrighten Movie
• Now double click on the “ProcAmpBrightness” and set its value to “0”.
• Now go to this path: HKEY_LOCAL_MACHINESOFTWAREIntelDisplayigfxcuiprofilesMediaDarken Movie
• From there, double click on “ProcAmpBrightness” and set the value to “0”.
• Then close the Registry Editor and restart your PC and then see if the problem’s fixed or not.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

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"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

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" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.

One of the worst Blue Screen of Death errors you can encounter is the UNMOUNTABLE_BOOT_VOLUME BSOD on Windows 10. In this BSOD error, your computer won’t be able to properly boot. Meaning to say, even if you want to reinstall Windows, you won’t be able to back up your important files. Thus, it wouldn’t be really feasible to fix the system files, and besides, reinstalling Windows 10 would take a lot of time, not to mention resources. The UNMOUNTABLE BOOT VOLUME error is the kind of BSOD error that occurs if Windows is not able to access the volume that contains the boot files. Resolving this BSOD error won’t be easy but you will surely manage by following the suggestions laid out below but before you go on, make sure to create a System Restore Point.

Option 1 – Try checking the hardware

If you got the UNMOUNTABLE BOOT VOLUME BSOD error while trying to update your computer to a higher version of Windows, then you need to check if you have the compatible drivers for the disk controller as well as re-check the drive cabling and make sure that it is properly configured. And if you’re reusing either ATA-100 or ATA-66 drivers, ensure that you have an 80-connector cable and not the standard 40-connector IDE cable.

Option 2 – Try using Automatic Repair

You might also want to use Automatic Repair in fixing the BSOD error. To do so, follow the steps below.

• You can start by creating and booting from a bootable Windows 10 USB Stick.
• After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
• Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
• Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 3 – Try fixing the Master Boot Record or MBR

The MBR or Master Boot Record is the location and is where the architecture of the operating system is installed. Thus, if either the location or the architecture has tampered with, it can cause lots of BSOD errors like the UNMOUNTABLE BOOT VOLUME error.

• Boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options.
• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

bootrec /fixboot

• After entering the command, wait until the process is completed and then restart your computer to apply the changes made successfully.

Option 4 – Run the CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you fix the UNMOUNTABLE BOOT VOLUME error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then reboot your PC.

If you encounter the MUP_FILE_SYSTEM Blue Screen error with a value of 0c00000103, then it indicates that the multiple UNC provider or MUP has got an invalid of unexpected data. This can lead to the fact that the MUP cannot channel a remote file system request to a network redirector, the UNC, or Universal Naming Convention provider. There are several ways you can fix the MUP_FILE_SYSTEM Blue Screen Error on your Windows 10 computer, you can try to check the hardware of your computer physically, update or rollback some device drivers, run the Driver Verifier Manager, remove any hardware you’ve installed recently or fix issues related to IRQ. Use the given options below as reference to fix the MUP_FILE_SYSTEM Blue Screen Error.

Option 1 – Try to physically check the hardware

The first thing you can do is to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card of the computer.

Lately, some users reported getting an error that says, “System doesn’t have any USB boot option, Please select other boot option in Boot Manager Menu” when they tried to reinstall the Windows 10 operating system on their PCs or boot from an installation media. If you have the same problem, then this post should help. This kind of error is applicable to multiple devices by various OEMs and is mostly due to the Secure boot being enabled, or the Legacy or CSM support being disabled. It could also be that the bootable USB device was not correctly made and so on. Whatever the cause may be, here are some suggestions you need to check out to resolve the “System doesn’t have any USB boot option, Please select other boot option in Boot Manager Menu” error and reinstall Windows 10 successfully.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the error. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try to reset the BIOS or the UEFI Settings

If updating the BIOS didn’t help in fixing Error 0199, you can try to reset the BIOS instead.

• Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
• Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
• Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
• Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

Option 3 – Make a proper bootable USB Drive/Stick

To make a proper bootable USB drive, you need to use the Windows Media Creation tool. The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

Option 4 – Try enabling Legacy or CSM boot support

If the Legacy or CSM boot support is disabled, then it’s no wonder why you’re getting an error. Thus, you need to enable it by following these steps:

• Open Settings and go to Update & Security > Advanced Startup options.
• Next, click on Restart Now to reboot your computer.
• After that, select Troubleshoot > Advanced Options where, you will see more options such as System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• From there, enable Legacy Support and then save the changes and exit. This will restart the computer.
• Once your computer has restarted, check if the error is now fixed.

As you know, just like other web browsers, Google Chrome offers Incognito Mode or private browsing which you can use to make sure that your browsing activities are not being tracked by any websites you visit and it also keeps targeted ads at bay. On the other hand, signing in to a website, even when in Incognito Mode is a different thing since that website can track your browsing activities. Thus, Incognito Mode is still useful especially if you want to browse the web safely and without getting tracked except when you log in to some site. However, there have been reports recently that Incognito Mode is missing in Chrome and users are clueless as to how or why it happened. If you are one of them, worry not for this post will walk you through what you can do if there’s no Incognito Mode in Chrome on your Windows 10 computer. This is an unusual and strange issue since the Incognito Mode in Chrome is available by default and you don’t have to do anything to enable it. It is possible that there might be corruption in the Windows Registry which caused the disappearance of Incognito Mode, worry not though for there are some tweaks you can apply to restore the missing Incognito Mode. To apply these tweaks, you need to create first a System Restore point, and then once you’re done, follow the instructions provided below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor. Step_2: Next, after opening the Registry Editor, navigate to this path – ComputerHKEY_LOCAL_MACHINESOFTWAREPolicies Step_3: From there, look for ChromePolicies and locate the DWORD named “IncognitoModeAvailability” and double click on it. Step_4: Edit the value of the “IncognitoModeAvailability” DWORD by changing its value from 1 to 0 so you can enable Incognito Mode in Chrome. Step_5: Once done, exit the Registry Editor and restart your computer and then check if you can now see Incognito Mode in Chrome. On the other hand, there is also another option that allows you to force open your Chrome browser in Incognito Mode. All you have to do is set the value of the “IncognitoModeAvailability” key to “2” instead of 0. This can be useful especially if you always browse the web in this mode. But you need to remember that you won’t be able to go back to the normal mode once you do this. Here are what the values of the IncognitoModeAvailability DWORD actually mean:

• 0 – Incognito mode is enabled by default
• 1 – Incognito mode is disabled
• 2 – Chrome is forced to always open in Incognito mode

Once a tedious and unfriendly task of installing fonts has been severely made easier and more user-friendly. As technology advances daily so do some tasks. One of these tasks which today look unnecessarily complicated is fonts installation in Windows. What was once complicated navigation to control panel with an administrative account, today is two-click with the mouse anywhere, well anywhere on your hard drive, but still a great improvement nonetheless. Ok, so you have found cool new font which you like very much and you are eager to try it out, but how do you install it in Windows so your other software can find it and use it? The task is incredibly easy, let's presume that you have downloaded desired font or fonts to your hard drive from the internet, they are nicely placed in a folder, all you have to do is select which one you would like to install, right-click on any one selected and click on install. That's it, that is all that you need to do. Now in order to remove fonts first, you will have to go to the folder which has all fonts installed in the system. The location of this folder is conveniently enough c:\Windows\Fonts. In there select all fonts that you would like to uninstall from the system and simply delete them, that's it.

The win32kfull.sys file is one of the kernel-mode device drivers in your Windows 10 operating system. In case you don’t know, there are two kinds of device drivers – the first ones are the normal drivers that communicate between your hardware and the operating system while the second ones are the kernel-mode drivers. The latter is necessary for booting your OS. And there are times when you encounter the win32kfull.sys error while booting your PC. Here’s the full context of the win32kfull.sys error:

“SYSTEM_SERVICE_EXCEPTION (win32kbase.sys) APC_INDEX_MIXMATCH PAGE_FAULT_IN_NONPAGED_AREA”

This error could be caused by corrupted or outdated drivers with incomplete files or it could be caused by some driver or software installed on your computer. To fix this error, here are some troubleshooting options you need to check out.

Option 1 – Try updating all the Drivers

As pointed out, the win32kfull.sys error can be due to outdated or corrupted drivers that are not compatible with your hardware. These drivers include but are not limited to display, network, sound, hard drive, and more. If you are not able to access the internet, you can just manually download the update using another PC. To update your drivers, here’s what you need to do:

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.

Option 2 – Identify and uninstall problematic programs by putting your PC in a Clean Boot State

One of the main causes of BSOD errors like win32kfull.sys is a problematic program that could clash with your existing operating system as well as computer architecture. There are tons of programs that are either incompatible or conflict with the existing drivers or software in your system. To identify such programs, you need to put your PC in a Clean Boot state. How? Follow these steps:

• 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 putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

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.

Error code 0xc000021a - What is it?

Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c. 

Solution

Error Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

• Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

• Premature unloading of Wbemprox.dll

• Newly installed third-party software is not compatible with the operating system.
