What’s New in Windows 10 KB5060533
While the KB5060533 update is primarily security-focused, it also includes fixes, originally tested in the KB5058481 preview update, alongside additional security patches typical of Patch Tuesday releases.
First of all, this update includes miscellaneous security improvements to internal Windows operating system functionality. While Microsoft has not detailed these changes publicly, the update includes “miscellaneous security improvements” designed to protect against emerging threats.
Clock Shows Seconds Again: The Calendar flyout on the taskbar now displays seconds, which is great for users who need precise time tracking at a glance.
Richer Calendar View: The Rich Calendar experience now shows events for up to 30 days, and it’s powered by Bing for more useful context. Additionally, the weather button in the Rich Calendar now includes descriptive text for better clarity.
GDI/GDI+ Text Rendering Fixes: Microsoft fixed issues where some GB18030-2022 characters weren’t displaying correctly or looked too wide. This improves text rendering and ensures better compatibility for affected languages.
Updated Mobile Network Profiles: Microsoft has updated Country and Operator Settings (COSA) profiles to improve mobile connectivity and performance on supported devices.
Account Sync Fix in EEA: A problem that caused sync issues with secondary accounts in European markets, leading to unnecessary server load, has now been fixed. This should improve account performance and reduce sync delays.
Hyper-V Fix: This update fixes an issue that caused Hyper-V virtual machines on Windows 10, 11, and Server to freeze or reboot unexpectedly. This bug was originally addressed in the out-of-band KB5061979 update released on May 27, 2025.
As a June 2025 Patch Tuesday release, Windows 10 KB5060533 includes 66 security fixes, with two zero-day vulnerabilities actively being exploited.
- CVE-2025-33053 (WEBDAV): A serious flaw in Web Distributed Authoring and Versioning could allow remote code execution, putting systems at risk if not patched.
- CVE-2025-33073 (Windows SMB Client): This vulnerability could let attackers elevate privileges on your device.
However, there are known issues that affect Noto fonts, where CJK (Chinese, Japanese, Korean) text might appear blurry in Chromium browsers like Edge or Chrome when display scaling is set to 100%. To improve clarity, switching to 125% or 150% scaling can help as a temporary fix.
