Drive letter missing in Windows File Explorer

It is no secret that Microsoft is trying to keep Windows relevant and that it is trying to make it as good as possible. A new Windows update will bring some interesting stuff in it which well some like it, some not so much. Among various technical and security updates Microsoft will bring some directly visible to each user.

First

of these features will be File explorer compact mode. This feature is a sort of spacing content in file explorer giving it easier access if you are using a touch screen device. Now, this feature is somewhat strange, and altho I can understand and get behind the logic of this move I am not sure I like it. Lucky for me and others who feel the same this option can be turned off for now.

Second

feature is something I can get behind, improvements for virtual desktops. There is an article on errortools about virtual desktops feature and I really hope you are using it since it is a great feature. Anyway, new update will bring us separate desktop wallpapers for each desktop and we will be able to arrange them in order we like.

Third

thing that I would like to address is animation features. We will have windows slowly fade and resize when opened, minimized, maximized, etc. So far we are unable to tell how this can and will it affect overall system performance. I am sure it will have some impact but hopes are that it will be kept to a minimum.

If you are trying to start the Microsoft Outlook application on your Windows 10 computer but you suddenly receive a message box with an error message that says, “We are unable to connect right now, Please check your network and try again later”, read on as this post will guide you on how you can fix this error. This kind of error in Microsoft Outlook could be due to some issues with your internet connection or it could also be due to the VPN software if you’re using one. Whatever the cause is, there are several potential fixes you can check out to fix the error. You have to check your internet connection or try changing it. You could also try to disable your VPN software or restart your computer or Microsoft Outlook and try starting the app again. In addition, you can also try entering your password again or check some settings in the Windows Registry or open Microsoft Outlook in Safe Mode. Refer to the guidelines provided below to further troubleshoot the problem.

Option 1 – Try to check your internet connection

The first thing you can do to resolve the problem is to check your internet connection. You have to make sure that you are connected to the internet and that it has a stable connection.

Option 2 – Try to restart your computer or Microsoft Outlook and try again

The next thing you can do to fix the error is to restart your computer or Microsoft Outlook. This simple process can actually help you fix the problem as it could only be a glitch that can be fixed with a simple restart.

Option 3 – Try to enter your password again

You could also try entering your password again to resolve the error. Just click on the Cancel button to open a dialog box and then enter your password again and see if it helps. Note that you might have to do it for all your email IDs in Microsoft Outlook.

Option 4 – Try opening Microsoft Outlook in Safe Mode and disabling its add-ins

Putting Microsoft Outlook into Safe Mode can help you identify the problems in it. Safe Mode also helps you fix a certain issue caused by some corrupted add-in. To start your Microsoft Outlook in Safe Mode, refer to these steps:

• Tap Win + R on your keyboard to open the Run dialog box.
• Next, type in “Outlook /safe” and press Enter to run the command.
• After that, it will ask you to select a profile that you want to use. Just simply select a profile from the drop-down menu and click on the OK button.
• Now you have successfully opened Microsoft Outlook in Safe Mode. As a result, it will start with disabling the add-ins. Meaning to say, there is some corrupted add-in that’s causing the problem, and that you need to look for that add-in and either disable it or have it permanently removed.
• Once you’ve identified the corrupted add-in, you can disable or remove it by going to File > Options > Add-ins. From there, select the option “COM Add-ins” from the drop-down menu and then click the Go button.
• Finally, close Microsoft Outlook once you’ve covered the given steps above and then try to open it normally.

Option 5 – Try disabling the VPN

As pointed out earlier, if you are using VPN, this could be the reason why you’re getting the “We are unable to connect right now, Please check your network and try again later” error so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there.

Option 6 – Try to check the settings in the Registry

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesNlaSvcParametersInternet
• From there, look for the DWORD named “EnableActiveProbing” and make sure that its value is set to “1”. When the value is set to 1, it means that it is Enabled. This is the default setting and is used to identify the status of the network connectivity of your computer.

DOTA2 involves teams of five players each, where each player chooses a “hero” character. Each game has two teams pitted against each other, on opposite sides of a map. Once you start, you and your teammates try to level up by fighting and defeating heroes from other teams as well as non-player characters who exist within the game universe. Once you have a strong enough team, you would then try to attack an opposing team’s base. If you destroy their “ancient,” your team wins. The teamwork and interactivity required to play the game are some of its biggest attractions. You can text and voice chat as part of the Dota 2 gameplay, enabling you and your team to come up with strategies to take over your opponents’ base and fortifications. For this reason, a properly working microphone and headset are important if you are to get the most out of this exciting online game. However, there are many times when you find that there are audio dropouts when you try to speak into your microphone. The question “How do I get my mic to work on Dota 2?” is one of the most commonly asked on gaming forums related to this game. Here are solutions for why this can happen:

1. You are logged in to another computer that is running the STEAM client

   While entirely rare, there are cases where the microphone in Steam is disabled because the same account is active and in use on a different computer. It may not notify you that your account is in use elsewhere. If this is the error, try to log out on other devices and then test it on only one system. If you cannot access the other computer that has access to your account, then change your password. This will automatically disconnect your Steam account from the other computer and let you enjoy voice chat in Dota 2 and other Steam games.

2. Your microphone is not properly set up in Dota 2

   From the main Dota 2 menu, before you start a match, you can set up your microphone for voice chat. At the top, left-hand corner, click the gear icon to open Settings Select the AUDIO tab and ensure that the Sound Device and Speaker Configuration are set to default. On the same tab, activate Voice (Party) and set your Push to Talk shortcut key for your team. Select the appropriate Open Mic Threshold using the slider at the bottom of this tab to get your microphone recorded at a comfortable level.

3. The Windows Audio Enhancements setting is turned on

   If you still cannot get your microphone to work properly, then your problem could be Windows Audio Enhancement. It is possible to get your microphone to work with Dota 2 by disabling these features. Right-click your volume icon on the system tray and select Recording Devices. Choose your active microphone then click its Properties button. On the Microphone Enhancements tab, make sure the checkboxes marked Voice enhancements and Acoustic Echo cancellation is unchecked Reboot your PC and retry using your microphone to chat.

4. Your audio drivers need to be updated

   If you try all of the steps above and still have Dota 2 not recognizing your mic input update mic drivers by going in device manager and choosing update driver.

If you got an error message saying, “Folder Redirection Failed, Failed to build the list of regular subfolders, Access is Denied” after you configured a new Group Policy Object or GPO which redirects User folders to a new network share or when you click on Reset default location under the Windows File Explorer or Folder Options, then you’ve come to the right place as this post will show you how to resolve this kind of error on your Windows 10 computer. Follow the given options below carefully to fix the “Folder Redirection Failed” error.

Option 1 – Take Ownership of the folder

If you are not able to access the folder could be one of the reasons why you’re getting the “Folder Redirection Failed” error and so you need to take ownership of the folder to resolve the problem. Before you proceed, make sure that your account is an admin account.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 2 – Try to add Authenticated Users or Domain Computers

Make sure that the Folder Redirection group policy removal option is set to “Redirect the folder back to the user profile location when the policy is removed” when using the Folder Redirection. After that, you have to add Authenticated Users group with the “Read” permissions on the Group Policy Objects or GPOs. And if the Domain computers are part of the group of “Authenticated Users”. Note that by default, the “Authenticated Users” have these permissions on any new Group Policy Objects or GPOs. Once again, you have to add just “Read” permissions and not “Apply Group Policy” for “Authenticated Users”. Furthermore, to fix the “Failed to build the list of regular subfolders” errors, here are some options that could help.

Option a – Try to clear disk space

You might have to check if your disk is running out of space because if it is, then it will fail to create a list abruptly. And so you need to free up some disk space. You can either check on the files manually especially if you tend to keep your files at random places in your disk drive.

Option b – Find the Target route

You need to find the target route of the folder and then restore it if you are getting the “Failed to build the list of regular subdirectories” when you try to relocate the folder to the original location.

Option c – Try to change Ownership/Reset Defaults for all the User folders

If the “Failed to build the list of regular subdirectories” error pops up when you are trying to move a large number of files from one location to another, then you need to change the ownership of the folders as pointed out earlier.

As you know, Microsoft Edge is the default web browser in Windows 10 operating system. It is a built-in browser that replaced the ancient Internet Explorer for its performance and features. Aside from being the default web browser, it is also set as a default PDF viewer in Windows 10. So if you open a PDF file, it will be automatically opened in the Edge browser even if you have installed a PDF reader on your computer. However, some users recently reported getting an error that says, “Couldn’t open PDF in Edge, Something’s keeping this PDF from the opening” when they tried to open a PDF file or view an internet link that has a downloadable PDF file in the Edge browser. If you are one of these users, read on as this post will help you troubleshoot the problem and fix it. This kind of error mostly occurs if you have installed other PDF viewers on your computer. They could be interrupting Edge while it tries to open the PDF documents. To fix it, check if Microsoft Edge is set as the default PDF viewer or you could also try to clear its browsing cache. In addition, you could also reset or repair Edge. For detailed instructions, refer to the given options below.

What is 0x3D55? As you know, Windows 10 is loaded with various Universal Windows Platform or UWP apps such as the Microsoft News, Weather, Calculator, Windows Mail, and many other applications that are based on the modern UWP platform of Microsoft that was introduced in Windows 10. Each one of these apps has a shared piece of code in the kernel for them to be able to get executed across any device that runs the Windows 10 OS which includes laptops, PCs, 2-in-1 devices, mobile phones, mixed reality headsets, and many more. However, there are times when the runtime information for these apps ends up getting corrupted which causes them not to function as expected and throws errors like the error 0x3D55. This kind of error can be pinned down when the UWP app malfunctions and you can also find an error message in the Event Log that reads, “0x3D55: Package family <App name with ID> runtime information is corrupted”. So if you encounter this error, read on for this post will walk you through fixing it. There are three suggestions you need to check out to fix this error – first, you can try to reset the Microsoft Store cache, second, you can try to re-register or reinstall the problematic app and lastly, run the Windows Store App troubleshooter.

Option 1 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right-click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “wsreset.exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterward, try opening Microsoft Store again and then try to install your app or update your computer again.

Option 2 – Run the Microsoft Store Apps troubleshooter

The Microsoft Store Apps Troubleshooter will help you in fixing the error 0x3D55. This is a great built-in tool from Microsoft that helps users fix any app installation issues.

1. Tap Win + I keys again to open the Windows Settings panel.
2. Go to Update & Security and then go to Troubleshoot.
3. On your right-hand side, scroll down to find the Windows Store Apps and then click on the Run the troubleshooter option and see if it fixes the problem.

Option 3 – Try to re-register the UWP app via PowerShell

• First, type “command prompt” in the Start Search and right-click on Command Prompt and then select the “Run as administrator” option.
• Next, navigate to this location in the command line utility: C:/Users/<Insert Username>/AppData/Local/Packages
• After that, execute the “DIR” command to view the list of all the directories in the given location.
• Once the list appears, look for the ID of the problematic app and take note of it.
• Now tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
• Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:

PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage Microsoft.<YOUR APP ID HERE>).InstallLocation + 'AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"

• Wait for the process to be completed and then restart your computer.

If you encounter an error message saying, “The ordinal xxx could not be located in the dynamic link library C:/Program Files (x86)/Microsoft VS Code Insiderscode – insiders.exe“ and you see a reference of a missing DLL file, then this indicates that the software is trying to locate the related DLL file, however, it is missing, hence the error. The error mentioned “Ordinal” which refers to the order of a number mathematically, e.g. 1st, 2nd, etc. And in this error message, the ordinal is referring to an Xth file of an XX.DLL file which is missing which is why you’re getting this kind of error. When you get this particular error, it means that your computer is missing the Microsoft Visual C++ Redistributable program. As per the error message, XXX is a number that in turn is the Ordinal. There is also another common error related to Ordinal which says, “The ordinal 12404 could not be located in the dynamic link library mfc90u.dl”. The error message could be referring to any DLL in the message. And since all these DLL files are part of the package, the error changes quite a bit as the Visual Studio looks for that DLL file. To fix this error, here are some suggestions that might be of help.

Option 1 – Try installing Microsoft Visual C++ Redistributable

As pointed out earlier, the error pops up when the Microsoft Visual C++ Redistributable program is missing on your computer. Thus, you need to download it from the official website of Microsoft. Once you’ve downloaded the Microsoft Visual C++ Feature Pack Redistributable Package, install it and then check if the error is now fixed.

Option 2 – Try to install OpenSSL

If you encounter the same error message but it points out that the LIBEAY32.DLL file is missing, then you have to install OpenSSL. In such a case, you will see the following error message:

“Ordinal not found. The Ordinal [Xxxx] could not be located in the Dynamic Link Library Libeay32.dll.”

 Make sure that when you install OpenSSL, you do it into the Windows system directory since the Libeay32.dll file is related to security.

Option 3 – Try to check Windows Updates

There are instances when Microsoft rolls out the framework and related updates via Windows Updates. It could be that an update related to DLL is still pending which is why you need to check Windows Updates. To do so, go to Settings > Update and Security and from there check if there is any pending update. If there is, you need to install that update and then restart your computer if needed.

If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics. If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot. There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /ScanOS
  • bootrec /RebuildBcd

• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.

Option 4 – 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
