When I type C+X C+O, vim crash all the time:(
The cream project provides vim installers for Windows: http://sourceforge.net/projects/cream/files/Vim/.
I could not find the version 7.3.088 but 7.3.75 and 7.3.98.
As @robi-wan mentioned, you should be able to find an appropriate Vim binary from the Cream project. I'm not sure why your Vim is crashing on <c-x><c-o>, however. If that issue persists, please open a new issue with an appropriate title (for example, "Vim crashes on <c-x><c-o>"), and provide some more information. For now, I'll consider this issue closed.
