I found this website while searching vista tweaks on google: Computer Modifications - Registry Tweaks

what do you guys think about those registry tweaks, are they safe, unsafe, benefitful or unbenefitful?

Hello,

They will work, but they are very drastic and heavy handed. If you do follow any, keep a good record of what you have changed and what from. For example, it is not always very wise to just kill all of your programs and threads, rather than let them shut down, however, it would improve shutdown slightly. It is your own choice, but hopefully someone else will give you a second opinion. Also, I would not try them all in on go!

IMO,

Richard

I tried them and they worked wihtout problem. Yeah im not too sure about the prefetch one, i set mine to 5. When i get home i willl check my prefetch folder to see if i have anything under prefetch. Actually i will delete everything from prefetch, then see if windows makes prefetch files while under the setting of 5. (I know that deleting prefetch files will hinder system performance, but i will test it just out of my curiosity).

I foudn more tweaks and will be trying them out soon, do you think these are legit?: http://tweakhound.com/xp/xptweaks/supertweaks11.htm

I will create a system restore point though.

i think the setting of 3 would be both boot and applications. I think i read somewhere that you can go to a setting up to 9 for the prefetcher. (it said higher the number more resources it iwll be dedicating to prefetching).

Alrgiht. I deleted everything from prefetch, including readyboost folder. My registry setting is at 5. I just need to wait a few more weeks and see is prefetch files start generating. Enable superfetch is still set to 3. Do you think i should put super fetch to 5 for this test to be accurate?
