There is no problem with cr2 files on Windows. The only minor annoyance is some newer bodies are not supported by Microsoft's raw viewer add-on, but that's no problem if you already use something else to do raw conversion.
My thoughts are: do you have the correct drivers installed for your system? Make sure the card reader is plugged directly into a USB2 (or USB3) port, although I guess anything slower is unlikely on a new system now. Avoid using an external hub to connect. Assuming the CF card isn't stupidly old/slow then the copy of 1.5 GB should take under a couple minutes or so. If you're using a very fast card, you might benefit from a faster card reader that uses USB3 for example. e.g. my Sandisk Extreme copies about 60MB/s with a Lexar reader over USB3 compared to ~20GB/s over USB2. Forgot to say, I'm using Windows 7-64 pretty much since launch without problem here.
Also if you use over-paranoid anti-virus software or other software that is looking at the card, that might be trying to simultaneously read from the card and slow things down.
