Windows XP build 2202

Windows XP build 2202.1 is the earliest available build of Windows XP. This build identifies itself as SD Windows 2000 Professional on the desktop watermark, where SD refers to the Source Depot version control system that Microsoft was deploying at the time.

This is the only known build to be built by a "ntvbl" lab (in this case being "ntvbl06") since labs were renamed to just "Lab" (e.g. "Lab06") a few months after this build was compiled.

Ties to Neptune/Whistler projects
For some time there had been a debate on whether this build is a post-RTM build of Windows 2000 or a very early build of Whistler. Many system files in this build contain strings beginning with, which indicates the source tree from which this build was compiled was initially located in the NTC2 folder. Considering it was compiled after the cancellation of the Neptune project, which had the source tree named NTC, it seems logical to assume that NTC2 refers to Whistler.

The Additional Drivers dialog in the Printers control panel also contains options for "Windows 2001" on AXP64 and IA64-based machines. The Resource Manager component from Neptune is also present. In addition, support for NDIS 3.0 was removed from this build. This has been verified by viewing the exports of. All this rules out the possibility of this build being a post-RTM build of Windows 2000.

"Comments?" link
The "Comments?" link from Neptune and later builds of Whistler can be added via a registry modification. To enable it, go to  and add the DWORD value   and set it to 1. The text of the link can be changed via a  string key. After adding the registry entries, log off and back on and open any application to get the link. The link does nothing when clicked in this build.

Installation
The unmodified version of this build cannot be normally installed (via CD boot) due to a bugcheck during setup. The user can either use a DOS boot disk to partition and format the drive and then run setup from there, or can replace   in the i386 folder on the CD with the one from a different build.

Drivers

 * VMware graphics drivers that are newer than version 7 cause a bugcheck at resolutions higher than 640x480 on newer VMware revisions (such as VMware Workstation 16).
 * Some USB devices will cause a bugcheck on boot with the error code . Removing the devices allow the machine to boot.
