Increasing GDI and User Handle Limits in Windows
Have you ever been working with a good number of applications at once? Do you work with heavy workloads and large files every day? Alright, answer this - have you ever had Windows buckle under the weight of all of these applications and display error messages stating that the system is out of memory or out of resources, buttons and menus do not work correctly, or you get an error sound but no message on the screen? I've hit this numerous times, to the point that I've lost work because of it...

Sometimes this happens even when you have a lot of system memory (RAM) still available. For instance, open up Internet Explorer and hold Ctrl+N to open up as many Internet Explorer windows as you can before menus, icons, and menus start displaying incorrectly, disappear, buttons aren't clickable, etc. Close a few out and check your Windows Task Manager in the "Performance" tab; I bet you will find that a lot of your Physical Memory is still available.
