Recently I noticed my explorer.exe was using 5,000,000K memory. After trying a bunch of things I decided to reformat my PC. After the format the mem usage was around 30,000K.
After re-installing some of my previous programs the mem usage is now fluctuates between 400,000 to 900,000. I am not having serious problems because i have 16GB of RAM but it has never been this high before. Any ideas why or how to bring down the mem usage.
