Windows Wellness Check

A one-click health check for non-technical Windows users that explains whether your PC actually has the latest critical security fixes, what those fixes protect against in plain language, and whether you should restart now or wait a few days.

Target user

Non-technical Windows users who want to know if their computer is safe after Patch Tuesday without becoming a security researcher

Features
  • Friendly 'is my PC safe right now?' scorecard after checking installed patch levels against the latest release
  • Plain-language summaries of this month's critical fixes and what they actually defend against
  • Smart 'restart now' or 'wait 48 hours' advice based on known patch stability issues and your hardware
  • Automatic alerts when a zero-day affecting your specific Windows version is announced or added to CISA KEV
Why now

With record 570-flaw Patch Tuesdays becoming routine and concerns that big batches introduce stability bugs, regular Windows users need a simple way to know what's safe to install without learning the lingo

Signals · overall 6/10
Demand
4/10

The leading consumer Windows-update-checker utility (Windows-Update-Checker on Softonic) has only 9K lifetime downloads and 164 in the last month, indicating very few non-technical users actively seek out a dedicated patch-health tool.Windows-Update-Checker (Windows) - Download

Whitespace
6/10

Existing consumer-facing Windows update utilities are explicitly described as 'not oriented toward casual users' and target Win 7/8/8.1, while available tools (ManageEngine, N-able, WSUS) are enterprise IT-focused — leaving a genuine consumer plain-language Patch Tuesday explainer gap.Windows-Update-Checker (Windows) - DownloadSoftware Update Checkers for Windows 11/10

Monetization
4/10

Antivirus subscriptions exist at $30-100/yr, but Microsoft Defender is free and built-in; comparable utility tools (Windows-Update-Checker) are freeware, so willingness to pay specifically for a patch-explainer is modest at best.Windows-Update-Checker (Windows) - Download

Longevity
9/10

Multiple 2026 sources confirm Microsoft patched a record 570+ vulnerabilities in a single July Patch Tuesday, with the trend structural (AI-assisted bug discovery) and unlikely to reverse.Microsoft Ships Record July Patch Tuesday with 570 Security FixesRecord-Breaking Microsoft Patch Tuesday Update: 570 Vulnerabilities

Feasibility
8/10

Buildable solo in weeks using PowerShell + the Windows Update Agent API plus Microsoft's free CVE/CVSS feeds wrapped in a simple GUI; comparable open-source projects (e.g., adrian3092/win-update-checker) already exist as proof of low complexity.GitHub - adrian3092/win-update-checker
