Ultimate Windows Tweaker : Feedback & Support.

[perfection]

I am using ultimate vista tweaker (recent version) and there is a tip to click the box corresponding to "disable the superfetch" (in order to acheibve a litle better optimization).

My questions in this regard are

(i) Does disabling the superftch also disable the prefetch (given to believe they are two diffrent though related issues) ?

(ii) I read that one can disable the preetcher and superfecth by manually editing the registry and setting the value to '0' after navigating the registry to this key
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters]

Therefore if i use the ultimate vista tweak to disable the superfetch how come after a reboot the registry value of this item is yet set to '3' ?

(iii) Does the disabling of the superfetch actually optiize system performance or not ?

(iv) Dies UVT mean superfetch as suprfetch or as far as this software is concerned does the term aso include prefetch because i belie when the superfecth tweak is set as disabled the prefetch also gets disabld -am i right ?

The Prefetcher is a component of versions of Microsoft Windows starting with Windows XP. It is a component of the Memory manager that speeds up the Windows boot process, and shortens the amount of time it takes to start up programs. In Windows Vista, SuperFetch and ReadyBoost extend upon the prefetcher and attempt to accelerate application and boot launch times respectively by monitoring and adapting to usage patterns over periods of time and loading the majority of the files and data needed by them into memory so that they can be accessed very quickly when needed.

IMO leave this alone. If you have limited HDD space then maybe remove it but that said I still wouldn't delete it.

Thanks Johnny.rotton but i am not deleting anything - i talked about three other things regarding the superfecth setting in the program (UVT) that i needed explained.

Thanks though!

No

It disables Superfetch service, so there is no need to set it to 0

(iii) Does the disabling of the superfetch actually optiize system performance or not ?

SuperFetch pre-loads commonly used applications into memory to reduce their load times, also keeps track of what times of day that applications are used, which allows it to intelligently pre-load information that is expected to be used in the near future.

Sometimes in network environment and stand alone as well, it cause delayed copying and moving files or file transfer on low configuration PCs.

(iv) Dies UVT mean superfetch as suprfetch or as far as this software is concerned does the term aso include prefetch because i belie when the superfecth tweak is set as disabled the prefetch also gets disabld -am i right ?

No, both are different and UWT disables Superfetch only.

Thank you very much Ramesh Kumar for all the answers.

However i wish you to explain one issue of the ones listed above

The question is - After tweaked with UVT for superfetch how come my reg entry for this does not become '0' (after reboot) or are you saying that there is another way to disable the uperfetch (maybe the group policies?)

One more issue that i noticed is that when i disabled the superetch (with UVT), there was no build up of .pf files in the prefetch folder leading me to believe that the prefetch too gets disabled and hence the doubts above.

UWT doesn't change any group policy settings, just diables the Superfect service. After that there is no mean what is set in reg values.

This is my 1st post, so not sure I am in the right thread. I am running Vista Basic SP2 on a Toshiba L300 series laptop; when I start UWT, the black bar on the left that contains the logo and tweaking categories is overlaying a portion of the right pane such that the first column of tweak boxes and some text is "blacked" out. Changing the laptop's resolution does not help. This is V1.2 of UWT and I use IE 7 or FireFox 3.5. I see other topics in the threads regarding GUI issues that had supposedly been fixed. Any suggestions?

Try the Beta of UWT 2.0....

Is there a facility to point to Special Folders? The old TweakUI had this so that you could point to Documents and Settings, My Music, My Album etc on anothe disk drive?
I kept all of that similar data on our D: so that in the event of a programme or OS crash then I didn't lose data.

Greetings from India and Jai Ho

Subseuqur\ent to your replies above i did extensive testing on this issue.

The superfetch disable tweak i spoke about changes a group poicy for thr sme and NOT the corresponsing registry entry (which remains '3' meaning that the suprfetch for boot an applications are enabled). But i agree that through the group policy the superfetch is 'off'. I have mnitoed the changes with a registry monitorto double check and after checking disable superfetch my group editor shows the change in poicy (and not the rgistry)

A group policy change obviously overides a registry change is what i believe

Can you confirm please
