Issue: How to fix KB5029649 fails to install in Windows 10?
Hello. When I tried installing the KB5029649 update on Windows 10 I received an error. Is it possible to solve this?
Solved Answer
KB5029649[1] is a Windows 10 security update that tries to address two major vulnerabilities that could jeopardize the system's security. The first vulnerability affects Internet Information Services (IIS) apps that use their parent application's Application Pool. Attackers can take advantage of this flaw to perform privilege escalation or bypass other security protections.
The second issue resolved by KB5029649 is with ClickOnce deployments. ClickOnce is a web-based platform that allows developers to distribute Windows-based apps. This vulnerability, allows an unauthenticated remote attacker to sign ClickOnce deployments without requiring a valid code signing certificate. Code signing certificates are used to validate software's validity and integrity. By evading this criterion, an attacker may be able to distribute malicious software that appears legal, deceiving users into running dangerous applications.
The consequences of these flaws can be severe and far-reaching. The IIS vulnerability, if exploited, might result in unauthorized access to sensitive information, unauthorized resource modification, and the execution of malicious code. This could result in data breaches, system compromise, and additional attacks on related systems.
Users are encouraged to deploy the KB5029649 security update as soon as possible to mitigate these risks. This update fixes the vulnerabilities and ensures that the security flaws are addressed. Furthermore, it is critical to keep all software, including the operating system and apps, up to date in order to reduce the danger of exploitation. Regular software updates and patches help guard against known vulnerabilities that attackers may exploit.

Access geo-restricted video content with a VPN
Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down.

Don’t pay ransomware authors – use alternative data recovery options
Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files – Data Recovery Pro.
