How to Fix Windows 11 Update Install Error 0x80071a91
1The Windows Update error code 0x80071a91 is generally associated with issues in accessing or processing update files. Here are the primary causes:
Corrupted Update Files or Cache:
The temporary update files stored in folders like SoftwareDistribution or Catroot2 might be damaged or incomplete, which prevents the update process from reading and applying the update correctly.
System File Corruption:
Essential system files required for the update could be missing or corrupted, causing the update engine to fail when trying to integrate new updates.
Permission or Access Issues:
The update process might not have sufficient permissions to access certain system files or directories. This could be due to misconfigured security settings or interference from antivirus/firewall software.
Third-Party Software Interference:
Sometimes, antivirus programs, firewalls, or other security software can block or interfere with the update process, especially if they mistakenly flag update files as a threat.
Incomplete Previous Updates:
If previous updates haven’t completed properly or are pending a restart, they can block the installation of new updates, leading to errors like 0x80071a91.
By addressing these potential issues—such as clearing the update cache, repairing system files, and ensuring proper permissions—the error can often be resolved.
