APC_INDEX_MISMATCH  - What is it and how to fix it?

You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

• First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
• Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
• After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.

Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
• From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
  • “This policy setting disables the acrylic blur effect on the logon background image.”
  • “If you enable this policy, the logon background image shows without blur.”

• Now click on OK and then check the login screen.

Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

When upgrading to Microsoft Windows 10, some users may encounter Error Code 8024402C. This error, while attempting to update, is a result of five possible issues. The error code itself is not a critical concern, yet while the error is occurring, users will not be able to upgrade their Windows software. As with any Microsoft error code, even if it is not critical, it is recommended that the error be addressed sooner rather than later. An insignificant error now could lead to a larger, more catastrophic error later on. Common symptoms include:

• A dialog box appears with the Error Code 8024402C when attempting to upgrade to Microsoft Windows 10.
• Your current version of Windows is unable to recognize the need for an update to Microsoft Windows 10.

One of the most useful utilities for advanced users in Windows is the Windows command line or Command Prompt. It is efficient in fixing system files, checking the disk for errors as well as other intensive tasks that are made convenient using this. One of the tasks you can carry out using Command Prompt is repairing the Windows bootup process if it encounters any issues. However, if you tried running the “bootrec/fixboot” command and you receive an error message saying, “Element not found”, read on as this post will guide you in fixing this error. This kind of error in the command line could be due to a damaged BCD or MBE, inactive system partition, or it could also be that there is no drive letter being assigned to the EFI partition. Whichever the case is, here are some possible fixes that should help you resolve the problem.

Option 1 – Try to repair BCD

As mentioned the error could be caused by a damaged BCD and so to fix the problem, you need to repair BCD by following these steps:

• First, make sure that you have a bootable Windows 10 USB drive with you and use it to boot your computer.
• Once you’re on the Welcome Screen, click on Next.
• After that, click on Repair your computer located at the bottom-left portion of the window.
• Then select Troubleshoot > Advanced Options > Command Prompt.
• After you open the Command Prompt window, execute the following command:

bootrec /fixboot

• Afterward, enter the next command below to rename the BCD file:

ren BCD BCD.bak

• Next, type the following command and make sure to replace “b:” with the letter of your bootable drive attached to your computer.

bcdboot c:Windows /l en-us /s b: /f ALL

• Now, wait until the process is completed and restart your computer to successfully apply the changes made.

Option 2 – Try assigning the drive letter to the EFI partition

• Tap the Win + X keys or right-click on the Start button and click on Command Prompt (Admin) to open Command Prompt with admin privileges.
• Then type the following command to start the Diskpart utility:

diskpart

• After that, if you receive a UAC prompt, just click on Yes to proceed.
• Next, type the following command to list all the volumes created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files:

list volume

• Now type the following command to select the desired volume:

select volume number

• Then type the following command to assign a letter to the selected volume:

assign letter=<LETTER>

Note: Make sure to replace “<LETTER>” with the letter you want to allocate to that partition. Afterward, it will assign a letter to the selected volume.

• Reboot your PC to apply the changes made.

Option 3 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

• Boot your computer using the bootable Windows 10 USB drive.
• Next, click Next when you get to the Welcome Screen.
• Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

diskpart

• Now type the following command:

list disk

• From there, select your primary disk by typing the following command:

select disk number

• After that, list all the partitions on the selected disk by entering the following command:

list partition

• The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
• Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

• Finally, type the following command to mark the partition active:

active

• Then type the “exit” command to exit the disk part utility.

If you suddenly see a black border in your computer’s display then you might be wondering how come this happened but worry not for this post will give you a couple of suggestions that could help you resolve the problem. The black bar could appear at the bottom or just the sides of the screen. Whichever it may be, there are options you can check out. Refer to the options givens below and make sure to follow them carefully.

Option 1 – Try checking the screen resolution

You might want to try checking the resolution of your screen.

• Open the Windows 10 Settings and go to Display.
• Next, go for the “100% (Recommended)” option under Scale and layout for the size of the text, apps, and other items.
• After that, select the Recommended setting again under Resolution.

Now check to see if the black bars are still there. They should be gone at this point, but if for some strange reason nothing has changed, then attempt the steps below.

Option 2 – Try updating Graphics & Monitor drivers

You might want to try updating your graphics and monitor drivers if you haven’t updated them for some time now. To do that, refer to these steps:

• 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 Graphics drivers or the Monitor drivers and then click each one of them.
• After that, right-click on each entry 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 can also try to roll back the graphics and monitor drivers back to their previous versions if updating them didn’t work. You can also try visiting the manufacturer’s website and download the graphics or monitor driver setup for your operating system.

Option 3 – Try to run the DISM tool

You can also run the DISM Tool as it might also help in getting rid of the black border or bar on your Windows 10 computer. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help you resolve the problem.

• 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.

Option 4 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Black border issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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” check box 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” check box.
• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.
