Windows Vista Build 5536 Download *Official*

"This page includes information to help you download the Windows Vista pre-RC1 ISO file. This pre-RC1 build is available for a limited time – we will close the program when we reach 100,000 downloads.
After downloading, please install and test the build as soon as possible. Most importantly, if there is a crash, hang, or error – please make sure that you send the information back to us using the built-in Windows Error Reporting technology (a dialog box will display automatically). Sending this information is essential to helping us improve the overall quality of Windows Vista – and collecting this information is the primary purpose of distributing this pre-RC1 release."
Once you complete the download you must burn the ISO file to a DVD. If you don’t know if your DVD-burning software will support burning an ISO file, please refer to your DVD-burning software program and search “Help” for instructions on creating a disc from an ISO file.
