Space on my windows 2008 Domain Controller -  C drive has  Changed without uninstalling any programs

I have windows 2008 DC. The space on C drive keeps changing.
In tha last couple of weeks the space  in C drive had increased from 600Mb to 1.4 Gb and again it dropped to 500mb after two days.
I checked it now  and the space has increased from  500Mb to 1.5Gb.
How  is this possible? .I have not uninstalled any programs.
This fluctation in the space have happened twice in the last 30 days.

Iam  thinking of expanding C to another 10 Gb using Paragon Hard disk manager 12 Server edition. On D drive i have 80 Gb free space.

I dont know what is happening in the background. Is this unusual ?.
It is making me bit concerned because it is my DC. Any ideas will be much appreciated.

    Pagefile is one item that is dynamic in action.
    Best idea is to use some program like windirstat or perhaps get a directory list export it to a csv at both points in time and run a comparison on both of them.

    Will it drop significatnly after u reboot ?if it is then it is page file issue.

    Just check any procedures are running in the task manager , it could be some log / audit program ...etc.

    Also check any schedule happening twice per 30 days.

    That issue might be related with increasing size of page file as it was suggested above. By default page file is set up to be dynamically expanded. You can move that file to another drive or just set up static disk usage to prevent its growing.

    Another part is WSUS (if used) during patches download and extraction, space might be overused. After patches are installed and/or server restarted then space would be free up.

    Another part are application logs. Check what there is installed and search for logs (*.log) files to check if some of them do not have too large size.

    However, I would check page file first.

    For moving pagefile, you need to reboot the server after the changes.
