Critical Decision FAQ

Is this version safe to use?

Only if marked 'Recommended' or 'Active'. These versions receive security patches. 'High Risk' or 'Prohibited' versions are unsafe for production use.

What happens after EOL?

Microsoft stops patching vulnerabilities. Your device becomes a target for malware. Compliance audits (ISO/GDPR) will fail.

Is this enterprise-ready?

Enterprises must stick to 'N-1' or 'Recommended' versions. EOL versions are major compliance violations.
