Error Code 0xc00000fd - What is it?

In its most basic essence, Error Code 0xc00000fd appears when a program can not be initiated. It can occur when a file or program is corrupted, incompatible with the current version of the operating system, or out of date.

This error code occurs primarily in Windows but is also present in previous editions of the operating system. The symptoms of this error and the resolution methods for each of these systems are essentially resolved in the same way.

Common symptoms include:

• Failure of programs to open properly, even if they were able to be opened in the past
• The appearance of an error message stating that the application couldn’t be started correctly

There are several different things that Windows 10 users can do to try to fix the appearance of Error Code 0xc00000fd on their machine. Some of these methods are fairly simple for the average user, while others may require advanced knowledge and comfort with diving into the deeper tools and settings of the Windows operating system. If you have difficulty in implementing the methods below, contact a qualified Windows repair technician to assist you in the resolution of the error code.

Solution

Error Causes

Error Code 0xc00000fd can arise when program files are not recognized properly by the operating system, when the operating system is no longer compatible with the program being run, when files are missing or corrupted, or when the program has been changed in a substantial way. Each of these causes requires a different method of resolution.

Further Information and Manual Repair

Several methods can be used to attempt to resolve Error Code 0xc00000fd on your computer. Basic users can use some of these methods, while others require familiarity with advanced tools and options in Windows. If you have trouble implementing the steps below, contact a qualified professional to assist you. Here are the top ways to deal with Error Code 0xc00000fd on your machine:

Method One:  Check for Updates using the Windows Update Tool

In some cases, compatibility issues can be resolved through updates and patches available directly from Microsoft via the Windows Update tool. This is most likely the case if you have not kept up with regular updates on your machine over time. In your settings, open up the Windows Update tool and run a scan to see if there are any required updates available for your programs or for the operating system itself. If there are updates, install them, then reboot your computer to make sure that all updates are able to be fully applied to your operating system. Attempt to open the program that caused the error after you are finished to see if this method addressed the problem fully or if an additional method needs to be used.

Method Two:  Roll Back to an Earlier Version of the Updates

Sometimes, an update can cause a compatibility issue. If you have previously been able to open the program in question without any problems, but have recently installed an update on your computer, that update may have been the source of the problem. If this is the case, roll your system back to an earlier stage of updates to see if that fixes the problem. If so, you may need to wait to reinstall the updates until Microsoft corrects the issue.

Method Three:  Run Scans on Your Registry, Antivirus Software, Drivers, and Update Troubleshooters

If there truly is a corrupted or missing file within the program that you are trying to run, you can open up several tools to scan for the file that may be causing the trouble and attempt to fix it. Run the following tools to try to fix the problems:

• Windows Registry Repair Tool (this particular tool may take some time to complete)
• Windows Update Troubleshooting Wizard
• Windows Drivers Updates
• Antivirus software or Microsoft Security Essentials

After running each of these tools, restart your computer to allow any necessary changes to be applied to your system. If the above methods do not fix error Code 0xc00000fd on your particular device or if you do not have the confidence and knowledge to implement these steps on your own, get in touch with a Windows repair professional who can help you to resolve the problem.

Method 4: Use An Automated Tool

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.

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.

Access denied error code 16 is tied to websites, it is an error which you will encounter when trying to visit some specific website or if you are unlucky on all of the websites. Lucky for us this error is fixable and in order for us to do this, follow this guide for possible solutions.

1. Check Date and Time, Incorrect date and time can often interfere with services in your Windows, browsers are not different and this can cause some websites not to be shown. Check your date and time and set it correctly if needed.
2. Try to access the website from another device. If you manage to open a website on another PC or some other device then keep reading in order to find the solution, if you can not, then the problem is on the website itself.
3. Turn off Firewall or antivirus. New antivirus and firewall applications can sometimes mark certain websites as malicious and will cut contact with them rendering them unable to be accessed or opened. Try turning the firewall and antivirus temporarily off and then try to access the website.
4. Try opening web site in another browser. To eliminate browser-specific issues and their configuration, try opening the website in another browser.
5. Disable PROXI server. Some applications, especially malicious ones can change your proxi setting in LAN. go to your LAN settings and turn off proxi if it is enabled.
6. Reset your Browser. If this issue is caused by bad data in your browser or by its settings and preferences, resetting the complete browser will solve the issue.
7. Use VPN. Sometimes the reason for you was not able to access some website might be because the site is not available for your region, to bypass this issue use VPN and reroute your location.

Same as in previous Windows versions, Windows 11 will also use certain applications as default ones for opening certain file types and file extensions. And yes, same as in previous versions it will come preconfigured for certain file types and associated applications like for example photos for pictures. Of course, users usually have their own favorite applications for certain file types and much more prefer to open them inside the application of their choice instead of the default one. We can change the default application like in previous Windows versions but this time there are two ways and overall more control of this process. Windows 11 has settings for choosing default file type applications and default file extension applications giving you more control of this process.

The opening setting for apps

Whatever you wish to change default application or default extension application you will need to open settings for default application. Follow steps to quickly go into it.

1. Press ⊞ WINDOWS + I to open settings
2. Select Apps on left
3. On the right part select Default Apps

Now you are in settings for choosing default applications

Choosing default application by file type extension

This is considering by Microsoft as a typical way to set default applications inside Windows 11. Once you are inside the settings app there is a box labeled Enter a file type or link type. Inside the search box, type in file extension that you wish to associate the application with like .JPG, .TXT, or other. If the file extension is not associated with any application you will be presented with a Choose a Default button, if however, the file extension is already associated with the app, you will need to click on the app box itself. In any case, a pop-up will appear and ask How do you want to open YOUR FILE EXTENSION files from now on? Choose Application from the list of presented ones and click on OK.

Choosing default file type

Another method is to select the default application by file type selecting application for it. In the settings screen, under the search box, you will have a list of installed applications. Choose the application that you would like to associate a file type with and click on it. On the next details screen scroll down and select the file type that you want to associate with the selected application and click on OK.

Other/third method

There is also the third method for choosing the default application for file type but it includes some surfing on your hard drive and it can be more time-consuming for first-time settings. But it is fairly quick when you need to only use it once on some new file type (for example you have a new application installed and want to switch just one file type extension to that application). Locate the file that you want to associate with the application and right-click on it. Select Open With from the menu and then Choose Another App. Pop up will appear, select the application that you would like to use, and check the box beside Always use this app to open CHOOSEN EXTENSION files followed by clicking on the OK button.

If your Windows 10 laptop suddenly turns off when you unplug its power cord, then you’ve come to the right place as this post will guide you on how you can fix this issue. One of the most common causes for this kind of issue is that there is some problem with your laptop’s battery. It is possible that it might have gone bad or has been damaged. However, this couldn’t be the case especially if the laptop is new. The problem could have something to do with the system settings, connections, laptop hardware, and so on.
