Windows 7 Beta 1 is now available to TechNet subscribers. The 64 bit and 32 bit versions are in the downloads section, along with a hot fix, language packs and a drivers pack.
I though it was Interesting to see the instructions to the DVD, “backup all MP3 files before installing Windows 7”. That hot fix in the directory also needs to be installed which solves the mp3 issue. The problem with Windows 7 and MP3s is covered by a Knowledge Base Article, (kb961367) and information about the problem can be found at BlogsDNA.
