Group Policy - Event Log Service | Security | Maximum Log Size (KB) forces a minimum size of 20480 KB.Explain text lists minimum as 1024 KB as following text:“If you enable this policy setting, you can configure the maximum log file size to be between 1 megabyte (1024 kilobytes) and 2 terabytes (2147483647 kilobytes) in kilobyte increments.”Eventvwr.exe lists minimum as 1024 KBIt's easy to reproduce this problem1. Open group policy editor2. Go to “administrative template” -> “Windows Components” -> “Event log service” -> “Security”3. Double click “maximum log size(KB)”You can not set log size smaller than 20480KB. But explain text said yes.We hope fix will be published soon.
