Malware infection:

In an ever-expanding digital landscape, malware threats are an unfortunate reality. Viruses and other malicious software can interfere with Windows Update, causing error 0x80240440.

Additionally, ensure that the service is set to automatic startup to avoid future issues. 3.

Windows Registry issues:

Corrupted or missing registry entries can impede the update process, leading to error 0x80240440. Utilize a reputable registry cleaner to scan your system and resolve any registry issues.
