Back on Friday, July 18th we reported that Microsoft had released an updated version of the performance trace visualization tool BootVis. As you may remember this new version resolves a compatibility issue when running on Intel Pentium 4 processors with Hyperthreading technology enabled and an issue when using third-party IDE drivers. To benefit from the new version however users running Intel based Hyperthreading technology setups require a Windows XP kernel hot fix in order to correct a problem with BootVis tracing. It's here now.
Important Note: This hotfix does NOT supersede Q820128: Windows XP Kernel Rollup Hotfix Package which includes additional files. Users that wish to be completely updated on the kernel, need to download both the kernel roll-up package and THEN this update.

The Q821581 kernel hotfix contains the following system files: Date Time Version Size File name --------------------------------------------------------------------- 29-May-2003 11:03 5.1.2600.1228 1,896,448 Ntkrnlmp.exe with SP1 29-May-2003 11:03 5.1.2600.1228 1,952,256 Ntkrnlpa.exe with SP1 29-May-2003 11:03 5.1.2600.1228 1,924,096 Ntkrpamp.exe with SP1 29-May-2003 11:03 5.1.2600.1228 1,928,832 Ntoskrnl.exe with SP1 At the time of posting Microsoft has not yet released a knowledge base article for Q821581. It's likely that the hotfix contains more fixes than just Hyperthreading compatibility with BootVis 1.3.37. Download
