Hi, The memory management algorithms were updated to address this problem in Windows 7 and Windows Server 2008 R2 operating systems. Therefore, we do not recommend that you use the provided functions or the Microsoft Windows Dynamic Cache Service in computers that are running Windows 7 or Windows Server 2008 R2. For more information, please refer to the following Microsoft KB article: You experience performance issues in applications and services when the system file cache consumes most of the physical RAM http://support.microsoft.com/kb/976618 But another TechNet blog updates the following information: As of August, 2011, we have found that there are certain conditions on Windows Server 2008 R2 RTM/SP1 where this service is required.

I have read several sites and many users are having the same issue we have - the cache on Windows 2008 R2 creeps up and must be reset using Cacheset or by rebooting. I was wondering is anyone has tried Dynamic Cache Service on 2008 r2? Or has anyone modified it to work with R2? The docx file states that it is for 2008 and before only. Any help would be great!
