This change did not introduce a new binary. It involved renaming the existing executable used for Calling and Meetings as a workaround for a Windows compatibility issue.&nbsp;<\/p>\n<p><b>What Happened?&nbsp;<\/b><\/p>\n<p>To reduce administrative effort, we partnered with the Windows team to deliver the fix for a Windows compatibility issue. With the Windows fix now fully rolled out in Windows 24H2 and 25H2, the executable name change is no longer required and has been rolled   back.&nbsp;<\/p>\n<p>Was this a security, reliability, or compliance issue?&nbsp;<\/p>\n<ul>\n<li><b>This was not a security or compliance issue.<\/b>&nbsp;<\/li>\n<li>It was a platform compatibility issue in Windows.&nbsp;<\/li>\n<li>No customer data, identity, or tenant configuration was at risk.&nbsp;<\/li>\n<\/ul>\n<p><b>Was my tenant impacted?&nbsp;<\/b><\/p>\n<p>Only organizations participating in our <i>Technology Adoption Program (TAP)<\/i> were affected.

The change has been fully rolled back for TAP participants, with no lasting configuration or behavioral changes on client machines. No administrator action is required.&nbsp;<\/p>\n<p><b>What if we haven\u2019t deployed recent Windows updates yet?&nbsp;<\/b><\/p>\n<p>We understand that many enterprises deploy Windows cumulative updates on managed timelines.&nbsp;<\/p>\n<ul>\n<li><i>There is no risk or degradation if the referenced Windows KBs are not installed.&nbsp;<\/i><\/li>\n<li>New features that depend on these Windows updates will <i>explicitly check for the presence of the required KBs<\/i> and will only enable when they are available.&nbsp;<\/li>\n<li>If the KBs are not installed, those features simply remain disabled\u2015<i>no functionality breaks and no admin action is required<\/i>.&nbsp;<\/li>\n<\/ul>\n<p><b>Windows updates that include the fix<\/b>&nbsp;<\/p>\n<p>The Windows compatibility fix is included in Windows updates for versions <i>24H2<\/i> and  <i>25H2<\/i>, delivered through <a href=\"https:\/\/support.microsoft.com\/en-us\/topic\/november-11-2025-kb5068861-os-builds-26200-7171-and-26100-7171-2e0512e4-3ad4-4da6-958c-a468a1af949e\" target=\"_blank\">  KB5068861<\/a>.&nbsp;<\/p>\n<p><b>What to expect next?<\/b>&nbsp;<\/p>\n<ul>\n<li>No changes to admin configuration or tenant settings&nbsp;<\/li>\n<li>No service disruption&nbsp;<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>MC1189656 | (Updated) Upcoming Change to Teams Desktop Client on Windows Classification planForChange Last Upd [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-14528","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/14528","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/comments?post=14528"}],"version-history":[{"count":0,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/posts\/14528\/revisions"}],"wp:attachment":[{"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/media?parent=14528"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/categories?post=14528"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/m365jp.net\/index.php\/wp-json\/wp\/v2\/tags?post=14528"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
