Oops. I was thinking ReadyBoost.

The more RAM you have the more frequently used programs will load at startup
when using prefetch.

I only prefetch my boot programs. I don't prefetch my frequently used
programs. This make startup a bit quicker.

How do you do that?

Registry hack!

Copy the below (between the asterisks) to a text file in notepad. Then save
as xxxxxx.reg

Run the file for the changes.


*********************************

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Memory
Management\PrefetchParameters]
"BootId"=dword:00000046
"BaseTime"=dword:0ca25fa5
"VideoInitTime"=dword:0000000f
"EnableSuperfetch"=dword:00000001
"EnablePrefetcher"=dword:00000003
"EnableBootTrace"=dword:00000000

*********************************

The line "EnableSuperfetch"=dword:00000001 is the key

The default is dword:00000003 which caches all

dword:00000001 is boot files only

Thanks! But that doesn't look like a ".reg" file: it's missing
"Windows Registry Editor Version 5.00".

I changed "EnableSuperfetch" manually.

You're right. I left that out. It should be as follows:

****************************************

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Memory
Management\PrefetchParameters]
"BootId"=dword:00000046
"BaseTime"=dword:0ca25fa5
"VideoInitTime"=dword:0000000f
"EnableSuperfetch"=dword:00000001
"EnablePrefetcher"=dword:00000003
"EnableBootTrace"=dword:00000000

If you were to read all the way down to the last entry on that page you will
see that someone else has already taken the author to task for his
misinformation.

Some contradiction, please do research this. practicing some googlefu, some
sites recommend. The values for dword are different than what you posted.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management\PrefetchParameters]
"EnableSuperfetch"=dword:00000002
"EnablePrefetcher"=dword:00000001

0=Off
1=Prefetch boot process
2=Application Prefetch
3=Prefetch both
