Windows 11 ↗
Summary iPlain-English security verdict for Windows 11, generated from its current health score, actively-exploited vulnerabilities, and latest supported version.
Windows 11 currently scores 85/100 — good. No tracked vulnerabilities are currently known to be exploited in the wild. The latest supported release is 10.0.28000.

Disclosure trend iNew CVEs published for Windows 11 each year (NVD). A higher bar means more disclosures that year — more scrutiny, not necessarily less safe.
Patch priority — what to act on iThe issues to fix first — actively exploited (CISA KEV) first, then by exploitation probability (EPSS), then severity. Each row's "→ fixed in" is the earliest version that patches it; "see advisory" means no fixed version is published.
Most urgent first — actively exploited, then likeliest to be exploited.
