Microsoft has acknowledged that its August 2025 security update (KB5063878) is causing non-administrator users to run into User Account Control (UAC) pop-ups when certain apps attempt to repair or update themselves.
If you’ve seen unexpected permission prompts after installing the latest Windows updates, you’re not alone.
The change wasn’t accidental — Microsoft tightened Windows Installer security to fix a vulnerability (CVE-2025-50173) that could have allowed attackers to abuse the repair process.
But the side effect is that some common programs now suddenly ask for administrator approval where they didn’t before.
What users are seeing
People have reported problems when trying to launch or repair software that relies on Windows Installer.
For example, running MSI repair commands (msiexec) now triggers a prompt, and apps like Autodesk’s AutoCAD and Civil 3D may flash UAC windows as they attempt background repairs.
According to the report, Older apps such as Office 2010 can even fail completely with error messages if run under a standard account.
In many cases, the repair happens quietly in the background — so instead of seeing a prompt to elevate, users may just get an error that the app couldn’t be configured.
- Running the program as an administrator (by right-clicking and choosing Run as administrator) often solves the issue.
- In workplace settings where users don’t have admin rights, IT departments can roll back the change using a special Group Policy fix Microsoft provides through its enterprise support channels.
Microsoft’s next steps
The company knows the current setup isn’t ideal. In a future update, Microsoft plans to give IT administrators the ability to approve specific apps to perform these repair operations without triggering UAC prompts every time.
That way, businesses can stay protected without constant interruptions for their employees.
Until then, the advice is simple: if an app suddenly demands administrator permission after the August update, it’s not broken — it’s Windows being extra cautious.
