Microsoft says recent Windows updates cause app install issues

Microsoft says the August 2025 security updates are triggering unexpected User Account Control (UAC) prompts and app installation issues for non-admin users across all supported Windows versions.

This known issue is caused by a security patch that addresses the CVE-2025-50173 Windows Installer privilege escalation vulnerability, which can allow authenticated attackers to gain SYSTEM privileges due to a weak authentication issue.

To address this security vulnerability, Microsoft has implemented new User Account Control (UAC) prompts that request admin credentials in various situations to prevent potential attackers from escalating permissions. Some scenarios in which these prompts may appear include running MSI repair commands (such as `msiexec /fu`), installing applications that configure themselves for individual users, and executing Windows Installer during Active Setup.

Additionally, this change can hinder standard users from deploying packages through Configuration Manager (ConfigMgr) that depend on user-specific "advertising" configurations, from enabling Secure Desktop, and when launching Autodesk applications, including specific versions of AutoCAD, Civil 3D, and Inventor CAM.

The complete list of affected platforms is extensive, and it includes both client and server platforms:

• Client: Windows 11, version 24H2; Windows 11, version 23H2; Windows 11, version 22H2; Windows 10, version 22H2; Windows 10, version 21H2; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSC 2016; Windows 10, version 1607; Windows 10 Enterprise 2015 LTSB
• Server: Windows Server 2025; Windows Server 2022; Windows Server, version 1809; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012

"A security improvement was included in the August 2025 Windows security update (KB5063878) and later updates to enforce the requirement that User Account Control (UAC) prompt for administrator credentials when performing Windows Installer (MSI) repair and related operations," the company explained in a Windows release health dashboard update on Wednesday.

"If a standard user runs an app that initiates an MSI repair operation without displaying UI, it will fail with an error message. For example, installing and running Office Professional Plus 2010 as a standard user will fail with Error 1730 during the configuration process."

Microsoft is working to address this known issue by allowing IT admins to enable specific apps to perform MSI repair operations without requiring UAC prompts, a fix that will be released with an upcoming Windows update.

Temporary workaround available​

Until a fix starts rolling out, as a temporary workaround, Microsoft advises users to run apps that use Windows Installer (MSI) as an administrator. To do this, open the Start menu or Search results, right-click the app, and select the 'Run as administrator' option.

Those who can't run apps as admins can request their IT admins to mitigate the issue by installing and configuring a special Group Policy using Known Issue Rollback (KIR) on the following Windows versions after reaching out to Microsoft's business support team:

• Windows 11, versions 22H2, 23H2, 24H2
• Windows Server 2025
• Windows Server 2022
• Windows 10, versions 21H2, 22H2

Microsoft is also working to resolve another bug caused by the August 2025 security updates, which are causing severe lag and stuttering issues with NDI streaming software on Windows 10 and Windows 11 systems.

Additionally, the company stated last week that it found no connection between the August 2025 KB5063878 security update and reports of failure and data corruption issues impacting solid-state drives (SSDs) and hard disk drives (HDDs).

At my current position, they aren't even loading 24H2 yet. It's a company that requires a high security environment and it was explained that's why they are in no rush to progress to 24H2. Personally I haven't considered 25H2 for my personal systems for the stuff you are encountering. Microsoft has progressed to sending updates out to the field without the rigorous in-house testing they once did, leaving it to the guinea pigs in the field. I guess it's a matter of needing fewer employees to boost profits and make the stockholders smile and give the CEO big bonuses. Bill Gates was more concerned with the quality of the product he released. Just saying.

Good suggestions but it's not my BIOS/CMOS. I tried a manual install of a

KB5077744, which produces a 1900401 error indicates something corrupt in my windows system after the update​

​

​

Nothing changed in the BIOS, and again it started after an UPDATE for Windows 11 Pro 25H2 I also get an error when running the Windows update troubleshooter, which produces an error, so it is my Windows, from what I can see. Updates strike again.​

Windows causes issues.

NOOOOO I cant believe anyone says that, the l;ast load of new programmers taken from a bus somewhere in Idaho and driven blidfolded to the programming suite at Microsoft cant have made that many mistakes to cause issues in windows. Sorry Windows Adverising Inc. Ltd. Plc. Ngb. Wht & Why

Youll be telling me next they were supposed to do it correctly and integrate it into the latest Windows software which i recall seeing on the discount shelves of WallMart & 7/11

I refer to infinite number of monkeys note.

Next thing we know there will be junior competitions on Disney Plus to design a new dll for Microsoft.

I thought OS2 had a good shot of being a good system. Maybe its worth a try now

Killed my Lenovo Mini, reloading it now. Wheee! Windows is so fun! At least I have a full day to set it up again. I thought it was the BIOS acting weird, my experience with Lenovo's outside of Thinkpads has had things happen to the BIOS very rarely. I kind of ignore this system, it has it's duties to perform, noticed yesterday they had stopped. Now I know for sure. I couldn't even get Medicat USB to load, it was that bad (loading sequence settings in the USB had something to do with that, it worked before).

Windows stopped being fun a long time ago.

Please remember it is now an advertising company NOT a software manufacturer they make more on adverts than software now

A dead PC is a sign that it has the wrong OS running it. If it had windows 11 on it chuck windows 10 or linux on it.

It never hurts to have an older secondary system running your favorite flavor of Linux. That way you are already comfy with Linux before (and if) you are ready to make the big move. Make sure you try a number of flavors and find the one best suited to you. Unfortunately not all your favorite apps have been ported to Linux yet.
