Interesting information has come out from Microsoft, Windows 11 dark theme will include a different sound theme from its standard light one. When in dark mode on Windows 11, the system sounds generally become softer, and they echo a bit, creating a more soothing experience that matches the overall look and feel of the dark mode. Flipping back to light mode brings the system sounds back to their normal level. However, even though the light model has slightly louder sounds than the dark mode, Microsoft has taken great care to make sure the audio is more soothing, according to a report from CNBC. The designers of Windows 11 took inspiration from an approach called calm technology. Microsoft’s Christian Koehn and Diego Baca wrote about calm technology in a post on Medium. In it, they said, “Windows 11 facilitates this through foundational experiences that feel familiar, soften formerly intimidating UI, and increase emotional connection.” According to a Microsoft spokesperson in a statement to CNBC, “The new sounds have a much rounder wavelength, making them softer so that they can still alert/notify you, but without being overwhelming.”

Qtcore4.dll Error - What is it?

Qtcore4.dll is a dynamic link library file that helps Microsoft Windows in loading several key components of the system.

Error Causes

This error code is triggered by a variety of reasons such as:

• Windows file allocation file gets damaged
• Your computer BIOS (Basic Input/Output System) are misconfigured
• The Qtcore4.dll file gets corrupt
• Registry gets damaged and corrupt
• Non-Microsoft program not running in tandem with Windows
• Malware attack
• Improper hardware driver software

Further Information and Manual Repair

Here are some ways of fixing the Qtcore4.dll error on your system:

1. Re-install the Program Causing Qtcore4.dll error message to pop up

As dll files are shared files sometimes due to program deletion and installation .dll file settings can get misconfigured, damaged, and corrupt. In such a scenario, you can try reinstalling the program that is causing Qtcore4.dll error message to appear on the screen.

2. Reconfigure your Mis-configured BIOS

If BIOS misconfiguration is the cause of this error code on your system, then try reconfiguring your system’s misconfigured BIOS.

• To do this boot the computer and then press the BIOS designated keys to enter the BIOS. The keys may vary from manufacture to manufacture but typically, the setup keys are F2, F10, F12, and Del.

There are times when you might notice that the Drive letter from the File Explorer is missing, right after you install an update in your Windows 10 computer. So if you are facing this issue right now, then you’ve come to the right place as this post will guide you on what to do to fix it. In case you don’t know, a drive letter represents a single alphabetic character which is through A-Z typically. This could be assigned to a physical disk partition, floppy disk drive or the removal device/ CD-ROM/ mapping network drive in your PC. In most cases, the drive letter “C:” is assigned to the first disk partition where the running Windows is installed. Thus, if the assigned letter is missing from either the Disk Management or the Windows File Explorer, it could result in inconveniences or will leave the partition inaccessible. To fix this problem, you can try to show the missing drive letters manually or make sure that the drive has a drive letter assigned in the Disk Management as well as assign the letter using a tweak in the Windows Registry. For more details, refer to the options provided below.

Option 1 – Try to show the missing drive letters manually

• Open the Folder Options from the Start Search and go to the View tab,
• Next, scroll down on the list of given options until you see the “Show drive letters” option and then check the box that’s marked against this option.
• After that, click on the Apply and OK buttons and then go back to the “This PC” window. You should now see the drive letters

Option 2 – Make sure that the drive has a drive letter assigned in Disk Management

As you know, every drive is assigned a drive letter in Disk Management. However, if it goes missing, you can still get it back through Disk Management. To do so, follow the steps below.

• Open Disk Management and from there, right-click on the menu of a partition or volume and you should see a function named “Change Drive Letter and Paths”.

Note: This function allows you to add the drive letter, remove the drive letter and change the drive letter. If the last option, namely, “Remove”, is selected and applied, the letter of the drive will be removed and won’t appear in Disk Management. Thus, this could be one of the reasons why a drive letter is missing.

• You need to click on “Add” to assign a letter to the selected drive in order to reverse the change. Note that you must assign the drive with the original letter because if not, the programs that rely on the original letter might not work as expected.
• If the original letter is already taken by a new drive, you need to change the letter of that new drive to another available letter.
• Then allocate the released letter of the targeted drive.

Option 3 – Try assigning the letter using a Registry tweak

The next thing you can do to fix the problem is to assign the letter using a tweak in the Windows Registry but before you do that, make sure that you create a System Restore point first, after that, follow these steps:

• Tap the Win + R keys to open Run and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMMountedDevices
• From there, check if a device is shown as being mounted at the specific drive letter and then right-click on that drive letter.
• Select the “Rename” option from the right-click menu to change the letter to any other available letter.
• Exit the Registry Editor and restart your computer.

Option 4 – Try to format the destination drive

Formatting the drive can also help you resolve the error. To format it, follow these steps:

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

Pinned Windows 10 Taskbar Items. One of the most used interfaces in the Windows environment is the Taskbar. It is where users like to pin their most-used programs as well as shortcuts with extra privileges and automated tasks. In fact, it’s a lot better than the Start Menu. So if any Windows Update messes up with your computer, or if you’ve just switched to a different computer, setting up the Taskbar with the very same set of programs you used to have is definitely not an easy task. But worry not as this post will guide you on how you can backup and restore the items on your Taskbar either manually or automatically.

Manual Backup:

• Tap the Win + R keys to open the Run prompt.
• Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the folder where you can see all the shortcuts or pinned items in the Taskbar.
• After that, copy all the files in the folder and paste them somewhere else as a backup. For instance, E:\Pinned Items Backuppinnedshortcuts.
• Next, tap the Win + R keys to open the Run prompt once more, and then type “Regedit” in the field and hit Enter to open the Registry Editor. When the User Account Control dialog box appears, click Yes.
• After opening the Registry Editor, navigate to this key – HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband
• Then right-click on the Taskbar folder and select Export.
• Now save the file with the .reg extension to another location like the E:\Pinned Items Backup folder and then name it.
• Close the Registry Editor.

Manual Restore:

Make sure to copy all the files to one of the drives if you are using another computer and then refer to the following steps.

• Tap the Win + R keys to open the Run prompt.
• Then type “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” in the field and hit Enter to open the same folder where you just copied all the shortcuts. Make sure to keep it open.
• Then open the backup folder where you saved all the pinned items and copy all the files there.
• Next, go to the Taskbar folder (%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar) and then paste your files in there. If you encounter a problem while doing so, just replace it with your own set of files.
• After that, go to E:\Pinned Items Backuppinnedshortcuts and then double click on tb-pinned-items.reg. If a User Account Control prompt appears, click Yes. This will add the registry file into the main registry hub. You will also get a dialog box that will confirm that data has been added to the registry successfully. Click OK.
• You should now see the items on the Taskbar. You have to restart Windows Explorer. To do so, end its process in the Task Manager.

Automatic Backup:

Backing up and restoring the pinned Taskbar items in your Windows 10 computer can be done automatically as well. But before you get started on the process, you need to understand what’s going on behind the hood first. First, you need to create two bat files and name them “Backup Pinned Taskbar Items” and “Restore Pinned Taskbar Items”. After you have that covered, refer to the following steps:

• Open the Notepad app and paste the following details and save it as “Backup Pinned Taskbar Items.bat.

REG EXPORT HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerTaskband “E:\Pinned Items Backuptb-pinned-items.reg” xcopy “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” “E:\Pinned Items Backuppinnedshortcuts” /E /C /H /R /K /Y

• After that, run the newly created bat file with admin privileges.

Automatic Restore:

• Open the Notepad app and paste the following details and save it as “Restore Pinned Taskbar Items.bat”.

REGEDIT /S “E:Pinned Items Backuptb-pinned-items.reg” xcopy “E:Pinned Items Backuppinnedshortcuts” “%AppData%MicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBar” /E /C /H /R /K /Y

• After that, run the bat file with admin privileges.

Note: Just so you know, there is a drawback to this process as we’ve noticed that any pinned apps that were downloaded from the Windows Store don’t appear in these places and any items downloaded and installed separately from the internet and then pinned.

In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:

The drivers for this device are not installed. There are no compatible drivers for this device.

The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing. Below are solutions provided for this particular error and how to eliminate it.

1. Run the Bluetooth Troubleshooter

   Press ⊞ WINDOWS to open the menu and select settings In settings choose Update & Security Go to troubleshoot and on the right panel click on additional troubleshooters Click on Bluetooth Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed Reboot your computer

2. Install Broadcom driver from official website

   Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update. However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them. After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.

3. Remove all Bluetooth drivers and USB controllers

   If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers. Reboot your computer and Windows will automatically reinstall and set all devices.
