Depending on the free space of your HD, how much to set. Your computer will give you a recommended amount at the bottom of the box, which is what it most likely has allocated. If your computer has the HD space, double the recommended amount as your min, and multiply that amount by 1.5 to set the max amount. Once finished, press OK.

Also, remember... A clean desktop is a happy desktop. The less items on there, the faster it will be when you minimize and switch windows.

Windows manages Virtual memory for you automatically, so you dont need to manage it. However, it is best to acquire a continuous block, so you should set your virtual memory to its maximum capacity, otherwise, it offers little benefits managing your virtual memory manually.

If you're going to manage your computer's virtual memory, it is best to have multiple HDD, create a specific partition for it and finally relocate the cache stores on various apps.

However, this requires some understanding on HDD stroking and partitioning as well as concurrent data access on different HDDs. Also, it is wise to split your applications from your OS and cross mapping their caches store to the HDD.
