Thank you for your feedback.<\/p>\n<p><b>[Introduction]<\/b>  <\/p>\n<p>We\u2019re improving the performance and startup time of calling features in the Microsoft Teams Desktop Client for Windows. To achieve this, we\u2019re introducing a new child process named  <i>ms-teams_modulehost.exe<\/i> that will handle the calling stack separately from the main application process (<i>ms-teams.exe<\/i>). This change optimizes resource usage and enhances meeting experiences.<\/p>\n<p>  <b>[When this will happen:]<\/b>  <\/p>\n<p>Worldwide, GCC, GCC High, and DoD: Rollout will begin early January 2026 and complete by late January 2026.<\/p>\n<p>Note: Timelines may shift due to year-end feature flag rollout freeze.<\/p>\n<p>  <b>[How this affects your organization:]<\/b>  <\/p>\n<ul>  <\/p>\n<li><b>Who is affected:<\/b> All users running the Teams Desktop Client on Windows.<\/li>\n<p>  <\/p>\n<li><b>What will happen:<\/b><br \/> \n<ul>  <\/p>\n<li>A new process (<i>ms-teams_modulehost.exe<\/i>) will appear in Task Manager under the main Teams process (<i>ms-teams.exe<\/i>).<\/li>\n<p>  <\/p>\n<li>This process is dedicated to calling features and improves performance.<\/li>\n<p>  <\/p>\n<li>No changes to user workflows or UI; however, admins should ensure endpoint and security software allow this new process.<\/li>\n<p>  <\/ul>\n<p>  <\/li>\n<p>  <\/ul>\n<p>  <b>[What you can do to prepare:]<\/b>  <\/p>\n<ul>  <\/p>\n<li>Update endpoint management and security software to allowlist <i>ms-teams_modulehost.exe<\/i> alongside  <i>ms-teams.exe<\/i>.<\/li>\n<p>  <\/p>\n<li>Communicate this change to helpdesk staff to avoid confusion during troubleshooting.<\/li>\n<p>  <\/p>\n<li>Update internal documentation if you reference Teams process names.<\/li>\n<li>Make sure the same QoS settings applied to <i>ms-teams.exe<\/i> are also applied to  <i>ms-teams_modulehost.exe<\/i>.
