=== Shell ===
Small design improvements (including updates to the icon sizes and spacing) have been made to the dialog that opens if there's something that needs attention before proceeding with a Windows update.
=== Settings ===
* A chart legend has been added below the battery usage graph under System > Power & battery. This feature is disabled by default, but can be activated manually by enabling the 45643758 velocity staging key.
* The "Detach VHD" button in the VHD properties page under System > Storage > Disks & volumes in the Settings app, initially implemented in build 27686, has been temporarily disabled.
=== Miscellaneous ===
The enhanced privilege protection for Admin Approval Mode, initially implemented in build 26040, has been updated to Administrator protection. It provides an additional layer of protection against malware and other threats by isolating sensitive data and processes. The User Account Control elevation prompt has also been changed to reflect this feature. Administrator protection is disabled by default, but can be enabled manually by setting the "UAC: Configure type of Admin Approval Mode" policy under Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options to "Admin Approval Mode with Administrator protection."
