I want to Free Up My C Drive and I am Using Windows 7. I Cleaned Up Using Disk Cleanup and Deleted Unwanted Files and removed Some Unwanted Applications, Actually I had to remove Some Little Wanted programs too

And I Freed Up to 3GB, Then I had to Reboot for Unstallation Completing
Then it Drop to 2.25GB again.

I need Help for this Guys. I searched on Google they all say to Use Disk Cleanup and So on... And I did Them all.
This Had Happened Before too. I was thinking to Ask about this Earlier and I forgot

One Day I freed Up to 5GB and After a Reboot it Became 3GB again. That was the time i was going to Ask Here


If I asked Before I would have Solved this by Now

Thanks
