This one is the best tweak for windows XP I ever found, and it works very well. With this tweak we will force windows to load kernel and drivers in memory.

Here is what you have to do :

1) Open the regedit tool (Start -> Run -> regedit.exe )

2) Use the navigation in the left and go to HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

3) Double click the DisablePagingExecutive attribute, and put 1 in the decimal value field
This will make the drivers and the XP kernel run in memory.

4) Double click the LargeSystemCache attribute, and put 1 in the decimal value field
This will improve performance of the kernel

5) Double click the IOPageLockLimit attribute. On some later versions of windows XP that doesn’t exists, so if this is the case you’re done. Otherwise you have to put to the hex value : 4000 for pcs with 128 mb ram, 10000 for 256 mb ram and if you have more put 40000. This value specifies how many bytes can be used for I/O operations in your system.

That’s it, enjoy your faster pc

Windows Vista have some great improvements in AutoPlay, but yet a power user usually want to disable it or configure it for better performance.

If you want to simply disable autoplay in Windows Vista, go to control panel and double click on the “Play CDs or other media automatically” to open the AutoPlay dialog.

Disable autoplay in Windows Vista

To disable autoplay globally, just uncheck the “Use AutoPlay for all media and devices”

Disable for a single type

To disable autoplay for a single type (eg. DVD movies, or audio CDs) first make sure that the “Use AutoPlay for all media and devices” is checked. Select the type that you want to disable and then select “Take no action” from the drop down menu. In the above example we disable autoplay for blank CDs :

You may know that Windows XP is not the best operating system in memory management. Many times you need to reboot your pc, just to clean the memory. Of course there is a simpler way to do this by creating a shortcut. Here is what you have to do:

1. Right click on desktop, New -> Shortcut
2. Copy/paste this piece of code in the location box: %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
3. Save the file
4. You are done! Now every time you need some memory double click on your newly created shortcut

In case you are bored to create the file, or you just don’t understand exactly what I write, just download the Memory cleaner from here (right click->Save As).

Whenever you perform a search using the search functionality in the start menu, Windows Vista also searches the files in your hard drive. Depending on the size of your hard disk and the amount of files that you have, this can make the whole process really slow.

To avoid such problems you can set windows not to search the file index :

1. Right-click on the Start Button and select Properties.
2. Click on the Customize button.
3. Uncheck Search Communications.
4. Set Search Files to Don’t Search for files.
5. Click OK.
