Windows 11 April Update Causes Backup Issues

Microsoft released update KB5083769 for Windows 11 a few weeks ago, which includes several important security fixes. However, users are reporting ongoing issues caused by this update. The most common complaints include BitLocker locks and errors with Remote Desktop connections. These difficulties appear to be not just temporary but are expected to persist until May 2026. Another serious issue concerns compatibility with various third-party backup programs.

Affected applications include Acronis Cyber Protect Cloud, Macrium Reflect, NinjaOne Backup, and UrBackup Server. Users of this software are experiencing significant difficulties that are impacting their data backup processes. The problems seem to stem from a bug in the Volume Shadow Copy Service (VSS). This Windows service is crucial for creating snapshots of files that allow for uninterrupted recovery after a backup. A failure or malfunction of this service can have severe consequences for data backup.

Reports indicate that users are advised to uninstall update KB5083769 to restore the functionality of their backup programs. However, uninstalling a security update carries the risk that the vulnerabilities addressed by the update could be exploited again. This poses a significant security threat. Microsoft has not yet issued an official statement regarding the issues. It remains unclear when a patch to resolve these conflicts will be released.

The next regular patch day is scheduled for May 12, 2026, which may present an opportunity for Microsoft to address the existing problems. Windows 11 Home users are particularly affected, as they do not have access to the advanced features of the Pro version that could potentially mitigate some of these issues. The differences between the versions could mean that some users are unable to resort to alternative solutions available in the Pro version. The ongoing issues with update KB5083769 raise questions about quality assurance at Microsoft.

In the past, there have been similar incidents where updates caused unexpected problems. Users are concerned about the impact on their systems and the security of their data. The community has already begun discussing possible workarounds to minimize the effects of the update. Some users recommend using alternative backup software, while others attempt to manually repair the VSS services. However, these solutions are not always successful and may carry additional risks.

Microsoft has previously emphasized that user security is a top priority. However, the current issues could undermine trust in the company's update strategy. Users are hoping for a quick resolution to restore stability and security to their systems. The problems with update KB5083769 affect a wide range of users worldwide. An exact number of affected systems is currently unknown, but the number of reports has significantly increased in recent weeks. Microsoft has stated that the company takes the reports of the issues seriously and is working on a solution. A company spokesperson said: "We are aware of the issues and are working to resolve them as quickly as possible."
