 There are two locking issues on Windows: Box cannot back up open files,
 and while Box is backing up a file, other applications cannot open it for

 Changing our access method to
 4EB8-8CBC-AD9655DE91BA1033.mspx Volume Shadow Copy Service] is probably
 the right fix for both of these, but it only works on XP and above, and I
 cannot install the SDK it on my development machine. I would also like to
 make it work with MinGW without requiring a restrictively-licensed SDK
 download from Microsoft.

 Please could someone use a Windows machine (XP or above, Windows
 Activation compliant) to download the SDK and [mailto:chris+sdk at qwirx.com
 send it to me]?

 Another option (workaround) might be to use the Windows command-line tools
 to create a shadow copy and back that up instead of the original. However,
 I think that would be a kluge, difficult to install, and difficult to
 detect and handle errors with.
