Can someone please explain cached memory?

Hi I have been using windows 7 ultimate 64bit and have noticed in task manager that 28% of my ram is being used and with further looking I noticed most of this ram was under cache. Does windows 7 cache applications I use most frequently into ram?

Thanks for any help

Yes, Windows 7 makes intensive use of pre-fetch/cache.. my system uses almost 50% of my available RAM ... This is completely normal...

Thanks both of you for the help windows 7 memory management sounds much improved and i'm guessing windows 7 will release the ram to applications which require it such as games

That is correct. The memory management routine built in to Windows 7 is an improvement to the routines in earlier versions of Windows. Unused memory is wasted memory, and in order to speed your system up, Windows makes use of the free space to store data which makes your system run faster. When called for, this data is then retrieved from RAM instead of the much-slower HDD. Should you run an application (including games) that require this memory space, then the management routine relinquishes that space and it is made available for your application.

For example, here is mine. I am running Windows 7 (64-bit) with a single instance of IE8 (64-bit) with 2 tabs and Office Outlook 2007 for my email.

Cached fills up physical memory
From the moment I turn on my computer the cached memory slowly goes higher and higher until it gets to 90%+ physical memory usage and I have to restart. I'm really not good with computers so I have no idea what's going on.
