Speed Up Windows Startup with a Processor Tweak

http://live.pirillo.com/ – One of my favorite chat regulars is SWAT. Not only did he send me a very cool cap to wear, he also sent me an excellent start up optimization tip via EyeJot.

By going to my live.pirillo.com page, you can click on the EyeJot screen at the bottom right and send me a video email! SWAT sent one to me, letting me know that he had noticed that lately my startup on my Vista machine seemed incredibly slow. He’s right, it is. SWAT pointed out that by default, Windows only recognizes one Core, instead of the four that I have. So let’s take a look at his advice.

  • Click on Start>Run
  • type msconfig and click OK.
  • Once that box opens, click on the bootup tab.
  • Under the Boot tab, click on Advanced
  • Click the box next to the number of Cores, and choose the proper number from the dropdown box.
  • Apply and save the changes. Your computer may require a reboot. If it does, go ahead and do so, and notice the difference!

Once I did this, selected four Cores and rebooted, I truly did notice a marked difference in how much faster my machine booted! Thanks, SWAT… for the advice, and the cool cap!

  2. Hey hey,

    I changed the number of processor that windows see’s to two as I have a e6600. While I was there I noticed an option for maxmem. Its currently at 2048. In theory can this be increased and if so to what? Yeah, I know that winxp 32 only see’s a certain amount of ram.

    System specs below – Got it for free – yes will be switching to vista 64 shorty after they get a descent SP together and the 3rd parties IE nvidia get there act together.

    Intel Core 2 duo 2.4GHz
    Nforce 680i sli

  3. Hi Chris,

    In the msconfig application, there is no bootup tab.. There is a General, System.INI, Win.INI, BOOT.ini, Services and Startup.. Which one is it?

  4. @Ray Medina
    You’re probably using XP and have to select BOOT.INI, press Advanced Options and in the window that pops up select /NUMPROC and select number of processors from the dropdown list.

    Will it work? Do not know…

  5. “Does not recognize more than one processor”. That’s a load of baloney.

    This tweak doesn’t speed up anything, and in fact can only be used to limit the number of CPUs Windows sees (for debugging/testing) which in turn will slow your computer down, duh.

  6. LOL, I can tell most you boneshead’s don’t even know how to check the event viewer for boot time logs and debunk your own stupidity that this tweak is bs.

  7. This is a myth

    With default settings Windows will use all availible processors at boot time. This setting was made available to limit the number of processors used for testing and diagnostic purposes. Also, this limit will remain in effect after boot is completed. This setting is nothing new and has been available since NT4.

  8. Yeah, total myth. Windows already recognizes both processors. You can prove this by going to the task manager, then to processes tab. Right-click on any given process, then click ‘set affinity’. It should have all of your available processors already checked.
