How to manually optimize the memory usage

In this post you can get technical support for computer memory management. Memory is the useful unit of computer system; you can optimize your computer's memory usage to reflect your specific needs. If your computer is used as a workstation instead of as a server, you can increase performance by devoting more memory to your programs. Your programs will work faster and the system cache size will remain the default size that was included with Windows XP. Or, you can set aside more computer memory for a larger system cache if your computer is used primarily as a server, or if you use programs that require a large system cache.

Follow The Steps to Optimized Computer Memory Usage
1. Click Start, click Run, type sysdm.cpl in the Open box, and then press ENTER.
2. Click the Advanced tab, and then under Performance click Settings.
3. Click the Advanced tab, and then under Memory usage use one of the following methods:
o Click Programs if you use your computer primarily as a workstation instead of as a server. This option allocates more memory to your programs.
o Click System cache if your computer is used primarily as a server or if you use programs that use a large system cache.

How to configure registry keys to generate the memory dump file

Dump files are created when an error occurs for which there is additional information that would be useful in diagnosing a problem (such as internal control blocks). Every data item written to the dump files has a timestamp associated with it to help with problem determination. Dump files are in binary format and are intended for DB2(R) customer support representatives.

This post provide computer help for how to windows use dumb file and how to create dump file.
You can configure entries under the following registry subkey to generate the memory dump file:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\crashdump The REG_DWORD entries are as follows:

Dump1Keys
Dump2Key

The Dump1Keys entry is a bit map of the modifier keys to use. The values are as follows:
#define CRASH_R_SHIFT 0x01
#define CRASH_R_CTRL 0x02
#define CRASH_R_ALT 0x04
#define CRASH_L_SHIFT 0x10
#define CRASH_L_CTRL 0x20
#define CRASH_L_ALT 0x40

The Dump2Key entry is the index into the scancode table for the keyboard layout. The following is the actual table in the driver.

const UCHAR keyToScanTbl[134] = {
