There is still little on the internet &#8211; but feedback in my blogs suggests that the July 12, 2022 security update KB5015811 is responsible for various issues with Exchange, SCCM and with PowerShell scripts. <\/p>\n<p><!--more--><\/p>\n<h2>Windows Update KB5015811<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/vg05.met.vgwort.de\/na\/8953144912f84e5e80025a8f81999bd0\" width=\"1\" height=\"1\">Cumulative update <a href=\"https:\/\/support.microsoft.com\/help\/5015811\" target=\"_blank\" rel=\"noopener\">KB5015811<\/a> was released by Microsoft on July 12, 2022 for Windows 10 Enterprise 2019 LTSC as well as Windows Server 2019. The patch addressed security vulnerabilities and fixed a PowerShell issue. Microsoft has not released a lot of information about this update (see also <a href=\"https:\/\/borncity.com\/win\/2022\/07\/13\/patchday-windows-10-updates-12-juli-2022\/\">Patchday: Windows 10-Updates (July 12 2022)<\/a>). Those interested in the details of the fixes are more likely to find answers in the cumulative preview update KB5014669. This is because a number of problems have been patched.  <\/p>\n<h2>Issues reported with update KB5015811<\/h2>\n<p>I had asked in the blog post <a href=\"https:\/\/borncity.com\/win\/2022\/07\/18\/verursacht-windows-update-kb5015811-performance-probleme-bei-exchange\/\">Is Windows Update KB5015811 causing Exchange performance issues?<\/a>&nbsp; whether the observations of blog reader Wolfgang P. can be confirmed. Wolfgang wrote:<\/p>\n<blockquote>\n<p>My Exchange 2019 DAG suffered a massive performance loss after installing KB5015811. Forwarding mails of e.g. 3 MB size was acknowledged with a pop-up \"Outlook is trying to retrieve data from the server\". The process was then completed successfully, but took about 3 minutes.<\/p>\n<\/blockquote>\n<p>He only got out of this problem by uninstalling the security update. In the German <a href=\"https:\/\/www.borncity.com\/blog\/2022\/07\/18\/verursacht-windows-update-kb5015811-performance-probleme-bei-exchange\/#comment-129189\" target=\"_blank\" rel=\"noopener\">comment here<\/a>, this is confirmed by a second Exchange administrator. There were other comments on the blog post with problem reports, with <a href=\"https:\/\/www.borncity.com\/blog\/2022\/07\/18\/verursacht-windows-update-kb5015811-performance-probleme-bei-exchange\/#comment-130284\" target=\"_blank\" rel=\"noopener\">this German comment<\/a> being interesting:<\/p>\n<blockquote>\n<p>We have massive issues with KB5015811 here on servers running a lot of powershell scripts. Just today a monitoring server went to the limit and produced full CPU load with Powershell.<\/p>\n<p>After uninstalling the KB everything runs normal again. Not exactly related to Exchange, but in any case I see a connection with Powershell which is also relevant in Exchange.<\/p>\n<\/blockquote>\n<p>This indicates, that something is consuming up performance due to the fixes in the security update.
