Change Server Core Page File

Autor brendon

Fragmented page files have been known to drastically effect system performance and when you have servers hosting connections for hundreds of users this is not a good thing. When building servers for numerous customers it has been common practice to hard set a page file to 1.5x RAM size (To a maximum of 4GB).

Seeing how System Properties is missing from Windows Server Core, changing the size and allocation of the page file has become a little more involved.

Be warned, the following instructions involve the use of the windows registry editor. Incorrect use can screw up your system. You make this configuration at your own risk…..

1. Open regedit.exe
2. Navigate to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Manager\
3. Edit the REG_MULTI_SZ entry named ‘PagingFiles’
4. Enter the drive letter, file name and required pagefile size, one line per file.
   eg. C:\pagefile.sys 512
5. Cross your fingers, reboot the server (shutdown /t 0 /r) and after logging on Task Manager should show the updated page file size.

Hope this helps…
