Because a combination of Windows 7 and virtualization makes life interesting.

Per Engadget, a Microsoft statement from last week claiming that the company would look into reports of Windows 7 causing premature battery degradation on notebook computers has led to Microsoft stating that Windows 7 isn’t to blame.

According to the company’s testing, the new tool, which reports when a battery is down to 40% of its designed capacity and suggests replacement, hasn’t reported a single false positive. Additionally, the tool uses read-only data from the battery, and is in fact incapable of tweaking the battery’s life span or internal data, as it merely reports the data it receives, and stacks the theoretical design capacity up against the current full charge capacity.

Microsoft has attributed negative reports to the mere fact that many people might not have noticed the degradation already taking place in their batteries, as most batteries start to degrade noticeably within a year. The company has also stated that it will continue to look into the issue, but for now this sounds like a bit of a non-issue.

Whether or not Windows 7 lives up to one of its featured claims about helping to use a notebook’s battery life more conservatively remains to be seen, both on conventional PC notebook hardware and on Apple’s MacBook, MacBook Pro and MacBook Air hardware.

If you’ve tried Windows 7 on your notebook hardware and have either positive or negative feedback regarding its effects on the battery life, let us know.
