View Full Version : MSCONFIG Tweak - Is this any good?

I went into MCONFIG and did a tweak I found off of youtube and I was just wondering if it's any good or if it will screw something up? I've attached a screen shot!

Edit: Well, I changed mine to 2, since I have a dual-core cpu, and it seemed a little faster. No reason to change it back to 1, as of now. *shrugs*

Apparently it does nothing for performance, but the only article I could find about it is only available as a cached site on yahoo:


The purpose of the setting is to put a limit on the number of threads that windows will use so you can test performance and stability of a multi CPU or multi core system.

What's the default settings for this? Say, if I want to go back to the original settings?

I don't think it does anything but say boot with 2 cpu's in msconfig and you don't need dual cpu's to load the boot processes.

We need some real world experience on this and find out if people really notice a difference in bootups enabling this option.

Please let us know if your boot times have lowered by using a stop watch or just monitor the time.

From my end i don't see any difference but i veries among the users here to give it a shot and let us know.

what you did will have zero effect. CaptN was right. its only for debug purposes when you want to use less cores than the number you have.

Ok I had done a little test, bear in mind that I have 2 users on this PC and mine is password protected so I lost 5 seconds or so in click on the user and enter the password:

No 4 Cores options selected:

Apparently it boots up in the same time, no performance boost selecting this option on MSConfig, the 2 seconds difference surely be the time I lost in selecting and entering the password for my user.

You can try yourself, check the Vista Forums (http://www.vistax64.com/tutorials/151819-boot-up-time.html) and use the ReBoot Time script provided.

Thanks to Brink of Vista forums for providing this useful info.

Hope this helps you.

I tried that tweak with the box checked and unchecked, several times and while the difference was only a few seconds, one thing that seemed a little faster was the loading of the SideBar and startup programs such as XFire, Steam, etc. down by the clock. Like I said before, no reason for me to keep the box unchecked, even if it is for a few seconds saved. ;)

The memory option is handy for limiting RAM to 3GB for Vampire Bloodlines. ::D:
