VMware vs. Microsoft: Why Memory Overcommitment is Useful in Production and Why Microsoft Denies it

In the ongoing virtualization war much has been written (pro and con) about the value of memory overcommitment, a feature VMware ESX has and Microsoft Hyper-V is lacking (XenServer, too, for that matter).

Why Disabling the Creation of 8.3 DOS File Names Will Not Improve Performance. Or Will It?

Background NTFS is relatively relaxed about file names. They can be quite long (255 characters) and may contain “strange” characters (nearly all UNICODE characters are allowed). […]

Free Tool – List Registry Links (REG_LINK)

Recently I got into a very interesting discussion with my colleague Nicholas Dille on various aspects of Windows x64. One question he brought up was especially intriguing: Knowing about registry redirection, it is not astonishing to find that the 32-bit version of the registry key HKLM\Software\Classes (aka HKCR) gets to be HKLM\Software\Classes\Wow6432Node. But there is […]
