Windows Explorer caches DLLs (Dynamic-Link Libraries) in memory for a period of time after the application using them has been closed. This can be an inefficient use of memory.Find the key [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer]. Create a new sub-key named ‘AlwaysUnloadDLL’ and set the default value to equal ’1′ to disable Windows caching the DLL in memory. Restart Windows for the change to take effect.I tried this after running a intense program,then watched the task manager;memory recovered it self.

There was a bug in windows 2000 that would cause the scheduled tasks folder to be searched when ever the user would browse network drives. Microsoft developed a fix for this bug. The fix fixed the problem and it also had nice side affect of speeding up browsing of Microsoft networks. Below are instructions how to apply the fix.

1. Open up regedit.
2. Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/ NameSpace.
3. Find a key named {D6277990-4C6A-11CF-8D87-00AA0060F5BF}.
4. Right click on it and delete it.
5. Restart

when you connect to a web site your computer sends information back and forth, this is obvious. Some of this information deals with resolving the site name to an IP address, the stuff that tcp/ip really deals with, not words. This is DNS information and is used so that you will not need to ask for the site location each and every time you visit the site. Although WinXP and win2000 has a pretty efficient DNS cache, you can increase its overall performance by increasing its size.

You can do this with the registry entries below:

************begin copy and paste***********
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
“CacheHashTableBucketSize”=dword:00000001
“CacheHashTableSize”=dword:00000180
“MaxCacheEntryTtlLimit”=dword:0000fa00
“MaxSOACacheEntryTtlLimit”=dword:0000012d

************end copy and paste***********

make a new text file and rename it to dnscache.reg. The copy and paste the above into it and save it. Then merge it into the registry

This will help increase your bandwidth for any network connection in Windows XP PRO.

1. Make sure your logged on as actually “Administrator”. do not log on with any account that just has administrator privileges. To log in as an administrator:
-click on start->logoff->logoff
-in the logon screen hold Ctrl+Alt+Del.
-in the user field type ‘Administrator’ <-case sensitive.
-in the password field type the password for the administrator (if you don’t have one leave blank)
-press ok

2. Start – run – type gpedit.msc
3. Expand the “Computer configuration” branch
4. Expand the “Administrative templates” branch
5. Expand the “Network” branch
6. Highlight the “QoS Packet Scheduler” in left window
7. In right window double click the “limit reservable bandwidth” setting
8. On setting tab check the “enabled” item
9. Where it says “Bandwidth limit %” change it to read 0– Click apply, OK, exit gpedit.msc
10. Go to your Network connections (start->my computer->my network connection-> view network connections). Right click on your connection, choose properties then under the General or the Networking tab (where it lists your protocols) make sure QoS packet scheduler is enabled.
11. Reboot , now you are all done.

The NTFS file system is the recommended file system because of its advantages in terms of reliability and security and because it is required for large drive sizes. However, these advantages come with some overhead. You can modify some functionality to improve NTFS performance as follows:

1. Disable creation of short names. By default, NTFS generates the style of file name that consists of eight characters, followed by a period and a three- character extension for compatibility with MS-DOS and Microsoft Windows 3.x clients. If you are not supporting these types of clients, you can turn off this setting by changing the default value of the NtfsDisable8dot3NameCreation registry entry (in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Filesystem) to 1.

2. Disable last access update. By default NTFS updates the date and time stamp of the last access on directories whenever it traverses the directory. For a large NTFS volume, this update process can slow performance. To disable automatic updating, change the value of the NtfsDisableLastAccessUpdate registry entry (in HKEY_LOCAL_MACHINE\SYSTEM\CurrentContolSet\Control\Filesystem) to 1. If the entry is not already present in the registry, add it before setting the value. (Add it as a REG_DWORD)

3. Reserve appropriate space for the master file table. Add the NtfsMftZoneReservation entry to the registry as a REG_DWORD in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem. When you add this entry to the registry, the system reserves space on the volume for the master file table. Reserving space in this manner allows the master file table to grow optimally. If your NTFS volumes generally contain relatively few files that are typically large, set value of this registry entry to 1 (the default). Typically you can use a value of 2 or 3 for moderate numbers of files, and 4 (the maximum) if your volumes tend to contain a relatively large number of files. However, be sure to test any settings greater than 2 because these higher values cause the system to reserve a much larger portion of the disk for the master file table.

Reboot after making changes.
