Windows 7 works pretty well by itself. But if you revert you can start to troubleshoot and do things one at a time. And find what it was you did or added that has a conflict.
When you uninstall device drivers, Windows will find its own driver. I thought this all happened only AFTER installing Apple's drivers.
There are Apple notes on Windows 7 with installation.
New or changed technotes are here:

Windows NTFS does not allow filenames with special characters that Mac's HFS allows. I went through and find and renamed all the offending files which would cause Explorer to hang and get stuck (but not blue screen).
