Windows XP Home/Pro Tweaks *Increase Performance DRAMACTICALLY*

[intx]

HungAppTimeout is exactly what it says, "Hung App Timeout" - Basically it's how long windows waits for a frozen application (or believes is frozen, sometimes it's wrong) before closing it. If you set it higher, you're less likely to lose whatever is in that program when it's hung.

1000 = 1 second
5000 = 5 seconds

If you always save your work and never have an application freeze for a second, then 1000 is fine.

There are some false tweaks in this post. The first of them is the EnablePrefetcher tweak. Only values 1-3 do anything.

1. Prefetch boot processes only
2. Prefetch applications only
3. Prefetch both

DisablePagingExecutive will do nothing for performance. The registry entry only applies to ntoskrnl.exe which is only a few MB in size and it always in use anyway. So regardless if this tweak is applied or not it will stay in memory.

LargeSystemCache is another example of poor advice. This is best left at 0.

The QoS tweak is just a huge myth. Here is how it really works right from Microsoft.

Clarification about QoS in End Computers That Are Running Windows XP
As in Windows 2000, programs can leverage QoS through the QoS application programming interfaces (APIs) in Windows XP. One hundred percent of the network bandwidth is available to be shared by all programs unless a program specifically requests priority bandwidth. This "reserved" bandwidth is still available to other programs unless the requesting program is sending data. By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending enough data to utilize it completely, the unused portion of the reserved bandwidth is available for other data flows on the same host.

So again a tweak that will do nothing for performance.

The final tweak is just hilarious. You want to know why? The tweak does absolutely NOTHING. There is no code even in the OS that even looks at this key. Not since NT 3.5, if ever.

Don't post tweaks if you don't understand what they do. All you are doing is misleading people into thinking they do. Also a note to everybody else. Just abou every tweak you here on the net or advice on optimizing Windows for performance is most likely wrong or just plain bad advice. The pagefile is a huge topic with tons of false information and bad advice.

You don't

More harm then good will come from Registry cleaners.

If you have to ask then you should not be using a regcleaner. You should only be deleting registry entries you know need to be removed like spyware or a long gone program.
