VHD Attach 3.50

Here is new version of VHD Attach.

Due to popular demand, you can now change drive letter from within application. While this is not strictly VHD related task, I got it as suggestion from enough people. See, if you ask for something enough times, it is done eventually.

This version should also work on Windows 8 but do notice that there was no extensive testing. Probably new version will be out when Windows 8 is officially published.
