Windows Error Code 0x80090026 Solutions

Solution 1: Running System File Checker (SFC)

The System File Checker (SFC) tool scans and repairs corrupted system files, which may resolve the `0x80090026` error. To use SFC:

1. Open Command Prompt as Administrator.
2. Type sfc /scannow and press Enter.
3. Wait for the scan to complete and follow any on-screen instructions to repair files.

Solution 2: Using the Deployment Image Servicing and Management (DISM) Tool

The DISM tool repairs the Windows system image and can fix underlying issues causing the `0x80090026` error. To use DISM:

1. Open Command Prompt as Administrator.
2. Type Dism /Online /Cleanup-Image /RestoreHealth and press Enter.
3. Wait for the process to complete, then restart your system.

Solution 3: Checking Cryptographic Services

Ensure the Cryptographic Services are running correctly:

1. Press Win + R, type services.msc, and press Enter.
2. Locate the Cryptographic Services entry.
3. Right-click and select Properties, then set the Startup type to Automatic.
4. If the service is not running, click Start and apply the changes.

Solution 4: Rebuilding Cryptographic Keys

Corrupted cryptographic keys can trigger the `0x80090026` error. To rebuild them:

1. Open Command Prompt as Administrator.
2. Run the following commands in sequence:
   cipher /w:C:
certutil –setreg chain\ChainCacheResyncFiletime @now
3. Restart your computer.

Solution 5: Temporarily Disabling Third-Party Security Software

Third-party antivirus or firewall software can interfere with cryptographic operations. Temporarily disable these tools to see if the error persists. Ensure to re-enable them after troubleshooting.

Solution 6: Resetting Windows Update Components

If the error occurs during updates, reset the Windows Update components:

1. Open Command Prompt as Administrator.
2. Run the following commands:
   net stop wuauserv
net stop bits
net stop cryptSvc
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 catroot2.old
net start wuauserv
net start bits
net start cryptSvc
3. Restart your computer.
