new KB959233: Speeding up Windows Vista


Recommended Posts

And when I posted it here and on AskVG.com long time back, a few ppl told that its a hoax and doesnt work. ;)

It is. It's been confirmed from Microsoft themselves that that doesn't do anything. It already uses your full amount of cores on boot except for a few seconds where it doesn't need it and it wouldn't benifit from having both+ enabled. It's a hoax 100%

may be Windows is able to autodetect the number of cores only after the boot is ended, so this option allows the boot process to be informed about the number of cores and start the boot process in parallel mode?

but why Microsoft didn't enable this option automatically?

why the boot process doesn't read the number of cores from the hardware config saved in the registry?

This is a mistery...

No, any detecting software needs to be loaded and run therefore slowing booting, so best presume one core get on with it, if chance of predefining based on later detection great idea.

Mark Russinovich replied to my email. He requested that I not post the entire email exchange verbatim, so I'll paraphrase.

In my email I suggested that these tweaks were totally useless. Mark agreed and added that they are "incorrect and potentially damaging guidance" and that the "[series] will be pulled."

I have a quad core, set it to 4 processors and rebooted. Didnt notice any increased performance, but I let it stay like that anyway..thanx

I'd probably say that one will get alot more benefits with Windows 7 given that they've parallelised alot more of the start up sequence. I guess one will only really see major benefits when it comes to systems with alot of services loading at boot up.

Haha, nice! I figured he'd say something like that, he is a very smart fellow.

This is very embarassing that something so blatantly wrong got up on a microsoft.com server. I (and others like MarkRus) are contacting the owners of this content to get it removed.

This setting has NO IMPACT on boot performance, except to limit it to make your system artifically SLOWER by disabling processors. This exists for debugging purposes only (for example, developers use this setting to test their applications/drivers in a simulated single core environment if they have a multi-core CPU).

What I'd love to know is how this was published in the first place; was it written by someone who manages the knowledge base itself or was it written by an MVP?

I don't know, but I'm sure the appropriate people will look into how this happened and take steps to prevent similar errors in the future. In the meantime, please don't alter this or any related settings as you could potentially hinder the operation of your machine.

WTF am i special or what?

i couldn't live with the fact i'm proven wrong, so i double checked.

when advanced boot options looks like this (deselected checkbox, showing 1, like it was when i first opened it) my system boots in 1min

when it looks like that it boots in 51secs. offcourse these times are not entirely accurate, cause i still have to activate/deactivate the chronometer, but it still *boots faster*

someone could perform the same test and videotape it

mine boots exactly the same speed with this...

Boot time can be inconsistent. Any difference you measured is likely random, and certainly has nothing to do with this setting.

then why does it happen two times in a row, with about exactly the same improvements?

did you measure by yourself?

you do realize Brandon Live works for microsoft and probably knows what he's talking about right?

the guys that wrote this article probably work at ms too :p

I do have faith in Brandon but, however it may be possible that the setting is working for that user.

you do realize Brandon Live works for microsoft and probably knows what he's talking about right?

And this article is from a Microsoft KB.

Sometimes it seems some guys from Microsoft don't really know what they are talking about, one way or another, including Bill Gates and Steve Ballmer :laugh:

Personally, since I mostly keep up my Vista machine 24/7, so any increase in boot time doesn't really matter to me anyway. :p

you do realize Brandon Live works for microsoft and probably knows what he's talking about right?

and that means he's an unbeatable ****ing authority right?

better go measure it yourself and report the results, i don't really give a **** where any of you work as long as you don't care about me

    • Display Driver Uninstaller (DDU) 18.1.5.5 by Razvan Serea Display Driver Uninstaller (DDU) is a utility for completely removing AMD/NVIDIA/INTEL graphics drivers and related packages from your system, attempting to eliminate all leftovers (including registry entries, folders and files, driver store). Though AMD/NVIDIA/INTEL drivers can usually be removed via the Windows Control Panel, this uninstaller tool was created for situations where standard uninstall fails, or when you need to fully remove NVIDIA or ATI graphics card drivers. After using this driver cleaner, your system will behave as though it’s the first time you’re installing a new driver—similar to a fresh Windows installation. As with all such tools, we recommend creating a restore point beforehand, allowing you to undo changes if issues arise. If you're having trouble installing an older or newer driver, try it—there are reports that it resolves such problems. Recommended usage: The tool can be used in Normal mode but for absolute stability when using DDU, Safemode is always the best. Make a backup or a system restore (but it should normally be pretty safe). It is best to exclude the DDU folder completely from any security software to avoid issues. You do NOT need to uninstall the driver prior using DDU. Requirements: .NET Framework 4.8 Compatible with Windows 7, 8, 8.1, 10, and 11 (32-bit or 64-bit) Note: Using on Insider Preview builds is at your own risk. Display Driver Uninstaller (DDU) 18.1.5.5 changelog: Added 'Reset to recommended' button for the Options. General fixes and improvements.

WACUP 1.99.51.24568 Preview changelog: Fixed a deadlock seen from the recent crash reports when doing some of the drag + drop actions within the media library window Fixed a loading crash seen related to a problem with some of the artwork cache image files being restored which should now be better handled allowing for the bad image to be removed without it failing Fixed a deadlock seen from the recent crash reports when the internal metadata cache clearing is triggered which could block the main ui thread for too long with this now being moved to a background thread Fixed some performance issues with some of the methods related to determining artwork support which mainly affected the local library import / refresh (this is still slower for some compared to other players because there's more data & artwork aspects being checked for which means doing more processing on a single file despite the best of attempts to reduce duplicate / heavy processing where possible) Fixed a crash with the JTFE based missing files hotkey which no one seems to have used for an age for this to appear (maybe it's time to seriously consider stripping out features that aren't being used) Fixed how some of the file types which use extra information to reference their sub-songs is handled which was preventing some from being correctly resolved back to their base file (noticed fixing above) Fixed an issue with the handling of files with underscores in their filepath which wasn't being correctly handled causing some of the filename to be lost when shown as the title if title reading is delayed Fixed a few things that might be behind NotSoDirect not being stable for some setups though am still not certain that the changes done for this are going to fully resolve the problem from the crash reports Fixed the OS toast handling when there's no prior shortcut in the OS start menu to now create the shortcut (needed to allow the yes/no buttons for the new build / post-release toast) to be done as a hidden one so it's less likely to cause annoyance for those not wanting to see it whilst still allowing this less than ideal OS api implementation requirement to be met to avoid toasts without the needed buttons Fixed a regression when moving from taglib1 to taglib2 which broke some of the handling in place to allow for external programs to still access files when wacup has a held open cached instance of the file Everything else Updated cppwinrt (gen_win10shell.dll) to 3.0.260520.1 (26 May 2026) Updated libcurl (libcurl.dll) to 8.2.1 (24 Jun 2026) Updated Monkey's Audio (in_ape.dll) to 13.15 (28 Jun 2026) Updated mpg123 (mpg123.dll) to 1.33.6 (6 Jun 2026) Updated OpenSSL (libcurl.dll) to 3.5.7 (9 Jun 2026) Updated pugixml to 1.16 (16 Jun 2026) Updated taglib (tag2.dll) to 2.3.0 (11 May 2026) Updated vgmstream (in_vgmstream.dll) to the latest Git commit from 28 Jun 2026 Download: WACUP 64-bit | 9.6 MB (Freeware) Download: WACUP 32-bit View: WACUP Website | Screenshots Get alerted to all of our Software updates on Twitter at @NeowinSoftware
