Solution 3: Delete the contents of the Windows Update download folder

1. First, Launch File Explorer by either double-clicking on its shortcut icon on your desktop or pressing the keyboard hotkey Windows Key + E.

(Click on the negative space in the address bar, copy-paste the above path and press enter)

A confirmation message should appear when you select delete, confirm your action to delete everything. Also, go ahead and clear your recycle bin after you are done deleting the Downloads folder.

Solution 4: Restart Windows Update Services

All Windows update related activities like actually downloading the update file and installing it are handled by a bunch of different services. If any of these services aren’t working properly/are corrupted, the 0x80004005 may be experienced. Simply stopping the update services and then restarting them should help.

To manually update windows – Launch your preferred browser, open the following link Microsoft Update Catalog and in the search box type the KB code of the update you wish to install.

Download the update file and once downloaded, double-click on it and follow the on-screen prompts to install the update manually.

Case 2: When Extracting Files

If the error explicitly occurs when extracting, first, try using an alternate extracting application ( Download 7-zip or Winrar Free Download). Also, make sure the file is actually an extractable file and isn’t password protected.

Another reason for the error may be the over-protective nature of your antivirus. Certain anti-virus applications prevent extracting zipped files to protect your computer, but if you are sure the compressed file you are trying to extract doesn’t contain any malicious files then go ahead and disable your antivirus temporarily. Now try extracting the file. If you were successful in extracting the file, consider permanently removing your current anti-virus application and installing another one.

Nevertheless, if both the above methods failed, we will try solving the issue by re-registering two Dynamic link libraries (DLL) using the command prompt.

Finally, restart your computer and try unzipping the file on return. The 0x80004005 error should not arise anymore.

If the 0x80004005 error appears while performing other file operations like copying or renaming, try running the Files & Folder troubleshooter. To do so:

1. Head over to the following webpage and download the necessary files: Automatically diagnose and repair Windows file and folder problems . Once downloaded, click on the winfilefolder.DiagCab file to run the File and Folder Troubleshooter.

2. Click on advanced and check the option to ‘Apply repairs automatically’. Click on the Next button to start troubleshooting.

3. A window inquiring about the problems being experienced will appear. Select the problems you have been facing by ticking the box next to them and finally click on Next.

Let the troubleshooter run its course, meanwhile, follow any and all on-screen instructions being displayed. Once done check if you’re able to fix Error Code 0x80004005 on Windows 10.
