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.

People are becoming more and more concerned with their privacy and Facebook's flagship messaging application is caught between it all. While still widely popular it has becoming to lose its ground due to many unanswered questions about privacy encryption. Lucky for all of us there are alternatives for more secure messaging.

SIGNAL

Arguably the most secure of all well-regarded messaging apps, Signal is the favorite of the European Commission, as well as newsrooms around the world. While Signal doesn’t disclose how many daily or monthly users the app has, Google’s Play Store says it has been installed more than 50 million times. While using Signal, each voice or video call connected through the app includes full end-to-end encryption. Signal takes an extra step by hiding message metadata so that the location of the original message is missing. While it asks for your mobile number, that number isn’t used with your profile. Instead, it acts as a numeric username. Once registered, you will find 1-1 chat, audio, and video calls, disappearing or “secret” chats, and a privacy lock so nobody can access the app even if they have your phone. Best of all, it’s completely free to use.

TELEGRAM

One of the biggest competitors to Facebook Messenger (and WhatsApp), Telegram is a very strong alternative. With more than 400 million users, it offers an interface that should feel right at home for anyone coming from Messenger. Telegram offers some huge benefits over Messenger, including features like groups that can hold up to 200,000 members for a chat. There is no limit on your media or chat size, and you can share all types of files between users and in groups. From a privacy standpoint, Telegram has robust security, but it is worth noting that only “secret” messages are end-to-end encrypted and can self-destruct. Non-secret messages can be stored on Telegram’s servers so you can pick them up between your devices quickly. That’s a consideration worth knowing prior to making Telegram your default Messenger replacement. Telegram is free across all platforms.

THREEMA

Rising in popularity, Threema is another privacy-focused alternative that has quickly become a competitor to Facebook Messenger. This paid service ($2.99 on both App Store and Play Store) is a pay-once, use forever option. Once you pay the small fee, you gain all of Threema’s touted privacy options, like open-source end-to-end encryption for both messages and calls. Like Signal, Threema won’t require you to link any phone numbers or emails to your account. All chats are handled anonymously, and the service generates a random user ID when you first open and register for the app. No data is collected from any of your chats and no ads are shown. The Swiss-made app does have its own servers hosted in Switzerland, which do not store any chat messages. Another privacy benefit of Threema is the notion that all of your contact lists, groups, and user profiles are hosted on your device, not on the Swiss servers. Because of that, Threema can once again state that none of your personal info is stored anywhere they have access.

Mac OS

A solid reason to switch to Mac from Windows PC is Mac OS. Based on Linux, offers more stability and better security than Windows but you will not be able to find a vast array of applications on it.

Even when Mac OS X (the first big one) was first introduced, it looked and felt like ages beyond Windows (Microsoft just recently made a slick and modern design with Windows 11). Under the hood, it turned out that the operating system itself is stable and incredibly fast & responsive. If you value stability and easiness of use, Mac OS is the Operating system for you.

Apple ecosystem

This one is easy, if you are already invested in apple devices like iPhone and iPad, having an apple computer is one step forward into the apple ecosystem and one more step into easy sharing of documents and data between devices.

Calendars, emails, photos, videos, documents, and many more can easily be shared and synched between devices with a single apple ID making workflows much easier than on other operating systems.

Development

Developers all around the world say that developing on Mac is much better and smoother than on PC, this has probably to do something with OS being based on Linux but whatever the case is, it is much smoother and it just feels better. Apple laptops are often the go-to choice of developers for a reason.

Also if you are in the development business for applications and services aimed at iPhone or iPod then there is no really another way than to be into the apple ecosystem and own apple hardware.

Professional software

A lot of professional-grade software exists for both the Windows platform and Mac OS but there is some software that exists exclusively for Apple hardware like Final Cut Pro or Logic Pro. Both applications are used by professionals and are industry-standard software.

Logic pro is used by industrial audio specialists all around the world and is used in professional studios. Final Cut Pro is also used worldwide by video editors and if you are specializing in any of these two fields Mac seems like a very reasonable platform since the software can not be found on Windows. These two are examples, there are other similar applications that are only available on Mac OS

Longevity

Apple hardware is made of high-quality materials and components and it is proven over time that it lasts longer than usual. There are iPhones out there that have 13 years and they are still working, G3 and G4 Macs that are still functional.

When buying Apple products they will outlive other ones if treated properly so in the end you could be saving money by purchasing them.

Windows 10 users a set of rules or standards called Network Protocols in communicating over the internet. These protocols are the ones that made sure that the data is correctly sent between computers. However, if any of the Network Protocol is missing in your Windows 10 computer, then you will most likely encounter a problem like not being able to browse the internet, or share files.

• After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

Option 5 – Try importing Winsock settings from another computer

If resetting Winsock or the Network didn’t fix the problem, then you can try to import settings from a computer that’s in good condition. You need to have access to the registry to get this done and then export and import a couple of settings. Refer to these steps to get started:

• 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, go to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices
• Next, look for two registry keys named “Winsock” and “Winsock2” and then right-click on each one of them and select the Export option.
• Now copy the registry keys to a USB drive and then copy the keys on the PC in excellent condition.
• Then double click on each one of them and it will install the WINSOCK keys.

Error Code 0x8007041d - What is It?

Error Code 0x8007041d is an error that arises during the Windows 10 Update process. In some cases, this error code can also arise during the Windows 10 Activation process. It is an error code that has been present in multiple versions of the software but usually arises when antivirus or registry issues interfere with the Windows Update or Activation software.

Common symptoms include:

• Inability to download the needed Windows 10 updates
• Inability to complete the Windows 10 Update process

If you are experiencing the Error Code 0x8007041d on your machine, there are several methods that you can use to attempt to resolve the problem. Several of the steps that are most successful for the resolution of this error require familiarity with registry and antivirus tools, so if you are unsure of your ability to complete these steps on your own, contact a qualified computer repair technician to assist you.

Solution

Error Causes

In most cases, Error Code 0x8007041d arises when there is a conflict between multiple antivirus or malware tools on the computer, if there is an issue in the Windows registry, or if your Windows Defender software is out of date. During the Windows Update process, the system checks to ensure that there are not any factors that are present that could introduce viruses to the system, so if there are any indicators that could present issues to the software, Error Code 0x8007041d will often arise.

Further Information and Manual Repair

For users who experience Error Code 0x8007041d, there are several steps that can be taken to resolve the issue. If the following methods are not successful for you or if you are unsure of your ability to undertake them on your own, contact a qualified Windows 10 computer technician.

Here are the best ways to attempt to fix Error Code 0x8007041d on your computer:

Method 1:  Remove Additional Security Software Apart from Windows Defender

In some cases, having multiple versions of malware or antivirus software installed on your computer can cause the Windows system to create conflicts between them, which can interfere with your ability to update. During the update process, the system may attempt to determine if there is any malware present, and having multiple kinds of antivirus software present on the same machine may return mixed results.

If you currently are running antivirus software that is separate from Windows Defender, consider removing it from your computer prior to running the update software. This may allow you to successfully complete your update process without conflict. Additional software can be reinstalled after the update is complete, but make sure to keep both sets of software up to date in order to lessen the chances of encountering this error code again during future updates.

Method 2:  Update Your Windows Defender Software

If you currently have Windows Defender as your primary antivirus software, check to see whether it is fully up to date. Out of date antivirus software can cause conflicts with the Windows Update process since the update to Windows 10 will not be able to be completed unless the system is free from viruses or malware.

If you are unsure of whether or not your Windows Defender is up to date, open it and run the process to check for updates, then re-attempt to run Windows Update. In some cases, you may want to restart your computer before running the Windows 10 Update process a second time.

Method 3:  Run the Registry Repair Tool

Another issue that could cause Error Code 0x8007041d is a problem in the system registry. If you believe that this may be the case, run the Windows Registry Repair Tool on your machine to check for and resolve any issues. This is a fairly simple and straightforward tool to use, but it can help you to resolve any number of problems that may interfere with your ability to update your Windows 10 software.

If you have taken the steps listed above, restart your computer before attempting to proceed with the Windows Update process. If the three methods listed above are not successful in completely resolving Error Code 0x8007041d on your machine or if you are not comfortable in your ability to implement these steps on your own, contact a qualified Windows repair technician who is familiar with the Windows Update process to assist you.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.
