Update Control Desktop 4.2.1 Preview
Pre-release
Update Control Desktop 4.2.1 adds an original update/pause icon to the EXE, window/taskbar, title bar and sidebar.
Download Update-Control.exe below. The icon is already embedded. Separate ICO (16–256 pixel frames) and PNG (1024 pixel) files are also included.
- Preserves the existing Store Friendly, Hard Block and Restore behavior.
- Adds optional SHA-256 publisher signing with RFC 3161 timestamping and signature verification for a trusted certificate you control.
- Updates screenshots and documents UAC, SmartScreen and antivirus detections separately.
Validation: Windows CI passed for this release commit, including controller recovery, WPF icon loading, all seven icon frames, real temporary-service/SYSTEM-task lifecycle, package integrity and real EXE extraction.
Microsoft Defender found no threats in a custom scan of these exact release files. The attached Defender-scan-v4.2.1.txt records the date, engine/intelligence version, output and SHA-256 hashes. This is a point-in-time file scan, not a SmartScreen reputation test, publisher certification, or a guarantee against future/other-vendor detections.
This preview is still unsigned. No suitable publisher certificate was available. UAC/Unknown publisher and SmartScreen warnings can still appear. A custom icon does not establish trust, and even publicly trusted signing does not guarantee immediate SmartScreen reputation. No Defender settings, exclusions, or machine trust settings were changed.
If you previously used the old batch blocker, choose Restore Windows first, then Store Friendly on a supported Windows edition for app installation. Live Windows Update and Store behavior on a representative client PC remains outside the automated tests.
