I have received several reports about problems with a freezing Windows taskbar or Start button on Windows Terminal Server (RDS). Seems like another bug caused by Microsoft with the latest updates.<\/p>\n<p><!--more--><\/p>\n<h2>A user notification<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/vg05.met.vgwort.de\/na\/56a1bd0b4bf8458faa7f9d3b444d9012\" alt=\"\" width=\"1\" height=\"1\" \/>German blog reader Franz contacted me on Twitter and describes there his experiences with the hanging Windows taskbar as follows (I've translated the German tweet):<\/p>\n<blockquote><p>Have quite funny effect on Terminal Server (serv 2022). If you are in Edge and then click on Startbar there is a pause of about 1-2 seconds. Probably since update to 20348.1487 Any idea?<\/p><\/blockquote>\n<p><img decoding=\"async\" title=\"Terminal Server 2022: Start is freezing in Windows\" src=\"https:\/\/i.imgur.com\/0ZFobza.png\" alt=\"Terminal Server 2022: Start is freezing in Windows\" \/><\/p>\n<p>Franz has the effect that the Start button freezes for 1-2 seconds on Windows Terminal Server, hosted on Windows Server 2022, when using the Edge browser. He suspects the update to build 20348.1487 (see <a href=\"https:\/\/borncity.com\/win\/2023\/01\/11\/patchday-windows-11-server-2022-updates-january-10-2023\/\">Patchday: Windows 11\/Server 2022 Updates (January 10, 2023)<\/a>). Regarding the question from Franz, the comment mentinoned below came to\u00a0 my mind.<\/p>\n<h2>Another user report<\/h2>\n<p>In my German blog post\u00a0<a href=\"https:\/\/www.borncity.com\/blog\/2023\/01\/24\/windows-10-11-microsoft-besttigt-taskbar-probleme-mit-barco-clickshare-app-kalenderintegration\/\" target=\"_blank\" rel=\"noopener\">Windows 10\/11: Microsoft best\u00e4tigt Taskbar-Probleme mit Barco ClickShare-App Kalenderintegration<\/a> (as well as in the cross linked English edition) I had reported about problems with an unresponsive taskbar &#8211; but there a slightly different error pattern occurs. But German blog reader Michael had left the<a href=\"https:\/\/www.borncity.com\/blog\/2023\/01\/24\/windows-10-11-microsoft-besttigt-taskbar-probleme-mit-barco-clickshare-app-kalenderintegration\/#comment-142116\" target=\"_blank\" rel=\"noopener\"> following comment<\/a> (I've translated the text):<\/p>\n<blockquote><p>Since the last Windows update the taskbar on a terminal server freezes for about 5 to 60 sec. Utilization, memory etc is all in dark green. When it occurs, no process has a high load either.<\/p>\n<p>Barco ClickShare is not present. There are already a few messages on the net about this. (incl. server restart and then goes for a few days).<\/p>\n<p>The whole thing is user independent, even administrator is affected. I could recognize connections in connection with Edge.<\/p><\/blockquote>\n<p>This coincides with what Franz had described on Twitter. Michael states that restarting the server fixes the problem for a few days. Franz then followed up with the following German <a href=\"https:\/\/www.borncity.com\/blog\/2023\/01\/24\/windows-10-11-microsoft-besttigt-taskbar-probleme-mit-barco-clickshare-app-kalenderintegration\/#comment-142133\" target=\"_blank\" rel=\"noopener\">comment<\/a>.<\/p>\n<blockquote><p>Identical problem<\/p>\n<p>However, the pauses in the taskbar are up to 20 seconds. Opened programs can still be operated. With time delay the clicks in the taskbar come then.<\/p>\n<p>At Administrator.de is also a report about it [GB: I suspect it is the post <a href=\"https:\/\/administrator.de\/forum\/terminalserver-2016-start-bzw-taskleiste-friert-sporadisch-ein-4484982555.html\" target=\"_blank\" rel=\"noopener\">Terminalserver 2016 Start- bzw.

But Taptip Kill did not bring any improvement.<\/p><\/blockquote>\n<p>The mentioned programs <em>Taptip.exe<\/em> or <em>TapTip32.exe<\/em> seem to be the <em>TabletInput<\/em> service.<\/p>\n<h2>A Microsoft Answers forum post<\/h2>\n<p>Franz mentioned about the Microsoft Answers forum post <a href=\"https:\/\/answers.microsoft.com\/en-us\/microsoftedge\/forum\/all\/windows-2022-server-rds-taskbar-regularly-lags-is\/eec361fe-8900-49c6-bfe1-3d20492af4f7\" target=\"_blank\" rel=\"noopener\">Windows 2022 Server RDS &#8211; TaskBar regularly lags, is slow, or freezes<\/a>, dated January 16, 2023, that contains the following description:<\/p>\n<blockquote><p><strong>Windows 2022 Server RDS &#8211; TaskBar regularly lags, is slow, or freezes<\/strong><\/p>\n<p>Taskbars on Windows 2022 Remote Desktop servers freeze for RDP users<\/p>\n<p>When attempting to click on the taskbar, for example to switch between apps or right-click for task management, we are noticing that there is a delay of between 30 and 45 seconds (varies) in all sessions, including admin and local.<\/p>\n<p>On Windows Server 2022 RDS, there are problems with the task bar and sporadic task bar freezing.<\/p>\n<p>If you click back into your application after the taskbar has lost focus, it will take a little while for the taskbar to respond when you try to click on it again.<\/p>\n<p>Both of our 2022 RDS servers are experiencing this, and a clean boot does not fix the problem. They are also properly patched.<\/p><\/blockquote>\n<p>So also there you can find this error pattern that on Windows Server 2022 the taskbar for RDP users freezes for a certain time when clicked.

There seem to be several causes. At this point I'm asking me, whether other users also has the problem and knows a cause and a solution?<\/p>\n<h2>Feedback on Facebook<\/h2>\n<p>I had posted the link to this post in various private German-language Facebook groups. I received feedback there as well. Joachim B. wrote in a comment:<\/p>\n<blockquote><p>Yes! Was wondering why this doesn't happen to anyone else. Windows Server vNext has the same problem.<\/p><\/blockquote>\n<p>Tom B. posted the following comment (the reference to 2019 is to be understood in the sense that I explicitly mentioned Windows Server 2022 as affected in my post):<\/p>\n<blockquote><p>Switched to TCP in RDP file, but this also occurs with 2019.<\/p><\/blockquote>\n<p>Regarding the switch to TCP, the post <a href=\"https:\/\/borncity.com\/win\/2023\/01\/31\/windows-11-22h1-rdp-issues-fixed-by-preview-update\/\">Windows 11 22H1: RDP issues fixed by preview update<\/a> is going around in my head. After all, the preview update is only available for Windows 11 22H1. However, I am unsure whether there is not another error here.<\/p>\n<h2>Causes and workarounds<\/h2>\n<p>I found interesting the explanation of Rene S. in the server group on FB, as a reaction to my post. There a possible cause including workaround for this problem shimmers through:<\/p>\n<blockquote><p>Had this once with a customer:<\/p>\n<pre>HKLM\\SYSTEM\\Software\\Microsoft\\TIP\\TestResults<\/pre>\n<p>lruns full. As soon as one deletes the entries everything runs again.<\/p><\/blockquote>\n<p>When I then searched for this key, there were many hits going back to 2021.

From what I can see, it seems to be only written to by MS Teams.<\/p><\/blockquote>\n<p>Microsoft Teams is described there as the cause of a problem that writes the mentioned TestResults key full. However, MS Teams as the culprit is negated in follow-up comments.
