Roblox

Applies to: All users

Symptoms

We’re aware of an issue where players on Arm devices are unable to download and play Roblox from the Microsoft Store on Windows.

Workaround

Roblox is working on a resolution to address this issue. Please refer to the Roblox support site for updates. Until the resolution is available, players on Arm devices can play Roblox by downloading the title directly from www.Roblox.com .

Citrix

Applies to: IT Admin

Symptoms

Devices that have certain Citrix components installed might be unable to complete installation of the January 2025 Windows security update. This issue was observed on devices with Citrix Session Recording Agent (SRA) version 2411. The 2411 version of this application was released in December 2024.

Affected devices might initially download and apply the January 2025 Windows security update correctly, such as via the Windows Update page in Settings. However, when restarting the device to complete the update installation, an error message with text similar to “Something didn’t go as planned. No need to worry – undoing changes” appears. The device will then revert to the Windows updates previously present on the device.

This issue likely affects a limited number of organizations as version 2411 of the SRA application is a new version. Home users are not expected to be affected by this issue.
