Windows 7 Mouse power eater.

I have both Windows Vista and Windows 7 on the same PC. I run a 64 bit version of Windows 7 and both Vista 64 and 32 bit. The problem is that no matter what mouse I choose to use on Windows 7, shortly after using the system for at least an hour I either have pointer problems or battery problems. I use the same mouse on Vista and it can go months without an issue with the batteries going low. I have used othe mice but I am used to using the MS Intellipoint. On both O/S's I have the latest drivers and where the MS system gives you a leaway on usage on the changing of batteries the Win 7 system gives you hardly any recovery time before replacing the second battery. I use mainly photographic and artware programs so The issue is lagely to do with the workspace management in windows. Power seems to be a high wastage on win 7 whereas win Vista just takes its time to boot in. The driver database in both Win 7 and Vista seems to be identical about the only difference I can find is in coordinate checksum amalgamation on a 64 bit datalog. Something needs to be sorted because this is not the ideal selling point for Windows 8. In fact I am even more put off of the newer interface because it seems to be catering for smudgey fingers more than the everyday user whom uses the computer to work for him.
