Guys my cached memory starts from 800mb to keeps on increasing to about 4.5Gb in no less than 2 hours of usage...which is visible in Task Manager. Right now it is currently at 3.1GB... I have closed all the application to check whether there is any change in RAM usage but it not helps even if i sum up memory from all processes in task manager it isn't equal to the memory used. Here is the screenshot So is this normal or should i clean install windows 10..by the way I am on latest insider build. Is this the memory compression that introduced in this build? Can anyone enlighten me?
