Reports of this issue have surfaced after recent Windows 25H2 updates, where affected systems begin crashing shortly after installation. In this blog, we’ll look at why this happens, what role rdbss.sys<\/strong> plays in the error, and the steps you can take to resolve it effectively.<\/p> When Windows installs an update<\/a>, it just doesn’t add new features or security patches – it also replaces or modifies core system components. These changes can sometimes create inconsistencies between updated system files and existing drivers or configurations. Some common triggers include:<\/p> Rdbss.sys is a system driver in Windows which is a part of the Redirected Drive Buffering Subsystem<\/strong> (RDBSS). When your system wants to access files over a network like shared folders or mapped drives – RDBSS plays an important role in facilitating those operations. It works closely with:<\/p> Usually, rdbss.sys keeps silently working in the background, but when there is a disruption – like a driver incompatibility or a mismatch caused by Windows update, this component may fail and appear as a BSoD error.<\/p> Since this issue is typically triggered by a mismatch between updated system components and existing drivers or software… the goal is to restore compatibility.<\/p> Since outdated or incompatible wireless drivers are another big reason behind the unexpected rdbss.sys blue screen error, update them on priority to mitigate this issue.<\/p> If the issue still persists, it’s best to reinstall the drivers. For this, right-click on your wireless adapter and select Uninstall device<\/strong>. When you restart your PC, Windows will automatically install the driver.<\/p> If the issue appeared immediately after installing a specific update, rolling it back may restore access. Restart your system after removing the update and see if the issue is resolved.<\/p> You may also run into the rdbss.sys blue screen error due to system file corruption. To fix this, we will run the SFC and DISM scans.<\/p> Some third-party tools – especially the ones that interact with network traffic, can conflict with updated system components. Consider temporarily disabling or uninstalling the following:<\/p> Restart your PC and see if the issue gets resolved.<\/p> BSoD errors like the rdbss.sys CRITICAL_PROCESS_DIED can interrupt the file writing process on Windows. If the error occurred while writing to the drive, it can result in data loss. In such scenarios, we recommend using a professional data recovery software<\/a> – Stellar Data Recovery Professional<\/strong> to reclaim your lost files.<\/p> The software helps you recover data in complex loss scenarios like BSoD errors, logical drive failures, lost partitions, and more. Download, install & launch the software on your PC and recover data using Stellar Data Recovery<\/a> is just three simple steps.<\/p>![\"CRITICAL_PROCESS_DIED\"](\"https:\/\/www.stellarinfo.com\/blog\/wp-content\/uploads\/2026\/03\/restart-window.png\")
