4+ Fixes For Fix Error Code 0x80004005 For Windows 7, 10

Error 0x80004005 is one of the less common errors found in Microsoft PCs, but it is nonetheless frustrating and occasionally even paralyzing to your Windows experience.

Thankfully, there is a way out. Read it below. To alleviate some of your concerns, many other people are experiencing this issue. Check out some of the many Tweets from similarly afflicted users below:

When it comes to desktop operating systems, Microsoft has control over the majority of the market. As of late 2016, Windows 7 accounted for 48% of the market, and Windows 10 had 24%.

With a total control of 72%, Microsoft dominates the desktop game, and these two pieces of software have become cornerstones of their success. Windows 7 and 10 have been praised for their unique features and user-friendliness.

Microsoft Support’s Lack Of Resources

*Edit: Microsoft has recently updated its site to provide some handy solutions. But don’t bail on us just yet- we have unique fixes and video tutorials below to solve the problem.

This support document also helps with the following errors: 0x80004005, 0x80090006, 0x8009001d, 0x80070002, 0x8007007f, 0x8007007e, 0x800705aa, 0x8007007e, 0x80004005, 0x800705aa, 0x80070002, 0x80004005, 0x800405aa, 0x80090019, 0x800703e7.

Microsoft is among the most unhelpful when it comes to helping customers troubleshoot problems they encounter. I have years of experience to back it up. But they seem to be turning a new leaf with Windows 10.

At the time of this writing, Microsoft doesn’t have support for these error codes on their website.

On their actual support page, they list the error codes without providing possible solutions.

Instead, they have an answers page, which reads like a forum. Its premise is similar to Yahoo Answers, as it allows users to ask questions based on various topics and other users to answer. I prefer it when the actual company has its answers, like Nintendo does on their Error Codes for the Wii.

However, the answers concept for Microsoft works pretty well, so check it out here if you have any additional questions. They also have experts who work for them, so the information ,is usually accurate.

When it comes to Error Code 0x80004005, there are a lot of variations. It is displayed as “Unspecified Error,” it is up to the user to determine what is causing the error. Sometimes, like with the Outlook error, it is easy to tell as only the Outlook program won’t work correctly.

However, many times, the error will affect many programs at the same time. Some of those programs are used for daily needs by regular users. And some can be used for business needs. An excellent example of such a program is Microsoft Dynamics AX, which is used for business management, including sales, logistics, client relations, etc. Of course, you need the help of a Microsoft Dynamics AX developer to use that tool properly.

In other cases, to do all the fixing, you will have to try various solutions until they work. For this list, I compiled the four most common causes of this error and the most effective ways to fix each.

Therefore, the first job the user must do when correcting this error is to determine what case it is. There are four common causes of this error when using Windows 7 and 10. Here they are:

How to Fix Error Code 0x80004005 For Windows 10

1. Windows 10 Update

This error is specific to Windows 10 and occurs when a user tries to download an update. This usually means that the update files are corrupt. Usually, Microsoft themselves will notice this error and be able to fix it within a week. However, if you want the update before then, it is essential to correct this error.

2. Microsoft Outlook Error

This will affect Windows 7 and 10 users; it most frequently occurs when a new message arrives through the Outlook app. The displayed error message reads, “Sending and receiving reported error 0x80004005: The operation failed.” This error will prevent you from sending or receiving emails.

3. Registry Key Error

The broadest error on the list, an error in the Registry Key, affects many programs, and it is hard to determine precisely what is causing it. Usually, it is caused by a virtual machine error or when trying to access shared folders.

4. Corrupt .dll file

A .dll file stands for a dynamic link library. It is essentially a library containing code and data used by more than one program at a time. This error is necessary to fix as it can make multiple programs misfunction simultaneously.

Solution For Case 1: Windows 10 Update

When updating on Windows 10, this error is caused by the corrupt update files. If you receive this error while editing, you are lucky because this is usually the easiest to correct.

The Windows Update Control Panel is actually causing the error. Therefore, downloading Windows 10 off Microsoft’s website should fix this problem.

Yes, you will have to go through the entire setup process again, and it will be a little more work than simply updating it from the Update Manager, but it will give you the update without the error.

Solution For Case 2: Microsoft Outlook Error

If you use Outlook regularly, this is an error you want to fix as soon as possible, as it makes it impossible to send or receive emails. This can be especially detrimental if you use Outlook for work or other important uses. Here are two methods that should fix this problem.

Method 1:  Disable the antivirus blocking feature

The most common cause of this error is your antivirus software giving a false positive report. If you have an antivirus software on your computer, try to resolve this issue by turning off the software. After turning off the software, check to see if Outlook is running correctly.

If it does, make sure to report this to software developer. A significant disadvantage of doing this is that the computer may not be well protected. Still, the developer should be able to fix this issue within a couple of days.

Method 2:  Disable Notifications of New Mail

If your computer doesn’t have antivirus software installed, turn off the Outlook notification of reporting new emails.

To do this, open Outlook and find the Tools menu in the menu bar. From there, click Options and choose Preferences. Then, select Email Options and uncheck the item titled Display a notification message when new mail arrives. After clicking OK, you will no longer receive a notification when receiving a new email, and this error should be fixed.

Solution For Case 3: Registry Key Error

To simplify it, a registry key can be thought of as a folder within Windows. An error in the Registry Key will cause this error and most likely affect many programs.

To fix, start by opening the Run dialog box. This can be done by pressing the Windows key and R simultaneously.

Run is listed, and click it to open the box. Once you open it, type Regedit in the dialog box and click OK. This allows you to open the Registry Editor.

Now that you are in the Registry Editor, type in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\ CurrentVersion\AppCompatFlags\Layers

During this step, you are checking if the registry key is already present. If it is, then delete it and test to see if the error is still present. Deletion of the registry key should get the error fixed in most cases. If that registry key isn’t present, then this is not the issue.

Solution For Case 4: Corrupt .dll file

As mentioned, this error will affect the functionality of several programs, so it is imperative that you fix the issue as quickly as possible. Luckily, it is a simple and quick fix.

  • Begin by going to the Start menu and click on All Programs->Accesories->System Tools.
  • From there, select Disk Cleanup and you’ll be told which files you can delete and how much disk space can be freed.
  • Select Temporary Internet Files and click Clean up system files button.

Although a corrupt .dll file is a complicated issue, the solution of just cleaning up the system files from the Internet will usually fix this issue.

When encountering error 0x80004005, another crucial step is to check if any data was lost or corrupted. Running a data recovery scan immediately can help retrieve deleted files before they are gone for good. Thankfully, data recovery software makes this process easy by efficiently scanning and restoring damaged or lost data resulting from this error. Acting fast to recover data is key, as over time those files may not be retrievable. Overall, having a good data backup and recovery solution in place provides peace of mind if 0x80004005 or other errors cause data loss.


Recovering Lost Data

Another important thing to keep in mind when getting this error is that many times it will result in lost data. This can be disastrous and should be avoided at all costs. Luckily, recovering lost data is possible if you catch it in time. However, once time goes by, some files may be lost for good and will never be recovered

There are several pieces of software on the market that provide this service. Checking your files regularly and performing a lost data scan right after receiving this error is crucial if you want to retain all of your data.

If you want to learn more about this type of recovery software and find the best one for you, be sure to read this article from FossBytes.


As you can see from the list, Error 0x80004005 can mean a broad range of things. From Outlook to update, it is most commonly associated with file or data corruption. Unless you are familiar with some computer programming languages, these things can seem daunting.

You probably weren’t comfortable with some terms in this article, such as “.dll file”, or “Registry Key”. They may seem complex and strange to you at first, but once you learn what they mean and how they work, you’ll understand that they really aren’t that complicated.

It’s not necessarily as important for you to understand how these programs or errors work, but more of how to fix them so you can continue to use Windows error-free.

Luckily, Windows 7 and 10 are both similar enough to each other that the solutions for fixing these errors are the same for both.

  1. For me the outlook data file (.pst) seemed to be the problem, altough scanpst.exe did not report any error on it. I removed it from the source directory and replaced it with an older backup .pst file, then receiving emails started to work. After that I used the import feature to import all emails from the replaced .pst file.
