How to Fix Unknown Error 0x80004005
The 0x80004005 error is a generic “unspecified error” that can occur in various situations within Windows. Because it’s not tied to a single issue, its cause can be hard to pinpoint. This error most commonly appears during file sharing or network operations, but it can also show up during Windows Update, or when you are unable to access a specific file or folder.
This guide will provide a series of effective solutions for the most common scenarios where this error appears.
Understanding the Error 0x80004005
This error code is a broad indicator of a problem that Windows can’t specifically identify. The primary causes are:
File and Folder Sharing: A permission or network access issue is blocking you from sharing or accessing files on a network.
Windows Update Problems: Corrupted update files or a malfunctioning update service can cause the error.
Email Client Issues: In some cases, the error occurs when sending or receiving emails, often due to a corrupted client or profile.
حلول خطوة بخطوة
Solution 1: Fix File and Folder Sharing Issues
If the error occurs during file sharing, the problem is likely with permissions or the network connection.
Check Permissions: Right-click the folder you are trying to share and select Properties > Sharing > Advanced Sharing…. Make sure “Share this folder” is checked and click Permissions. Add your user account and grant it “Full Control.”
Use the Registry Editor: If the permission change doesn’t work, you may need to add a registry key.
Press the Windows key + R, type regedit, and press Enter.
Navigate to the following path:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem
In the right pane, right-click and select New > DWORD (32-bit) Value.
Name the new key LocalAccountTokenFilterPolicy and set its Value data to 1.
Restart your computer.
Solution 2: Fix Windows Update Errors
If the error occurs during a Windows Update, you will need to reset the update components.
Press the Windows key + R, type cmd, and press Ctrl + Shift + Enter to open Command Prompt as an administrator.
Stop the BITS and Windows Update services with these commands, pressing Enter after each:
net stop bits
net stop wuauserv
Rename the update cache folders with these commands:
ren C:WindowsSoftwareDistribution SoftwareDistribution.old
ren C:WindowsSystem32catroot2 Catroot2.old
Restart the services with these commands:
net start bits
net start wuauserv
Close the Command Prompt and try to run Windows Update again.
Solution 3: Fix Corrupted System Files
Corrupted system files can cause the error in any of the above scenarios.
