How to Solve Errors
Here are several solutions you can try to resolve error code 0x80070426:
Run the System File Checker (SFC)
Open Command Prompt as an administrator and type the following command:
sfc /scannow
This utility scans for and attempts to repair corrupted system files.
Check Disk Space
Ensure your hard drive has enough free space for Windows updates or software installations. Delete unnecessary files, uninstall unused programs, or consider moving large files to an external drive.
Disable Antivirus Temporarily
Temporarily disable your antivirus software and try the operation that was causing the error. If it succeeds, add an exception for the Windows update or installation process in your antivirus settings.
Run DISM (Deployment Image Servicing and Management)
Open Command Prompt as an administrator and execute the following commands:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
These commands check for component store corruption and attempt to repair it.
Reset Windows Update Components
Open Command Prompt as an administrator and run the following commands sequentially, pressing Enter after each one:
net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
Check File Permissions
Right-click on the folder or file where the error occurs and select Properties. Go to the Security tab and ensure that your user account has the necessary permissions (Read, Write, Execute).
Perform a System Restore
Use the System Restore feature to revert your computer to a previous point in time when it was functioning correctly. Be aware that this will undo any changes made after the restore point.
If none of these solutions resolve the issue, you may consider seeking further assistance from Microsoft support or a qualified computer technician.
