Do Post-EOS patches also apply to Windows Server 2008 (non-R2)?

No. Although both R2 and non-R2 2008 servers reached their end of support in January 2020, there was only sufficient demand for R2 security patches. If your organization has a large number of non-R2 Windows Server 2008 computers that you'd like to protect with 0patch, please contact [e-mail].
