Method 2: Enough Free Space

The earlier hard drive came with huge spaces, but this is the era of SSD. Most PCs come with 512 GBs of SSD space which becomes filled in a short period of time. Due to the unavailability of free spaces when you try to download and install the latest Windows Update, you may receive the 0x800f0805 error.

To solve this problem free up some SSD spaces by deleting junk files, removing unused large files, taking backups of pictures and videos to an external drive, etc.

Method 3: Temporary Disable Third Party antivirus

The firewall and antivirus programs are designed to block suspicious incoming connections to your PC so that they could protect PCs from attackers. Sometimes due to unknown reasons, the security program starts considering the Update server as a malicious server and blocks the connection to them. In this situation, the PC couldn’t make connections with the Update Server and failed to download the update file with error code 0x800f0805.

If you are continuously getting the above error, disable third-party antivirus temporarily and then download the updates.
