Today I was asked to create a group policy which sets the maximum size of security, application and system event logs.
So I opened group policy editor, navigated to Computer Configuration\Windows Settings\Security Settings\Event Log\Settings for Event Logs and defined these settings
Maximum application log size
Maximum security log size
Maximum system log size
Unfortunately GPO applied to computers, but values had not changed.
It turned out that defined values that are not multiliers of 64 do not work. I set 102400 for 100 MBs and polices worked as expected.
