Some media and storage devices can cause crashes of computers running the latest iteration of the Windows client, Microsoft informed.

The Redmond company did not offer a specific list of hardware products that have problems playing nice with Windows 7, but the software giant did deliver a few details.

Not only Windows 7 computers are impacted by this issue, but also Windows Server 2008 R2 machines.

According to reports from users, the crashes are associated with freshly installed third-party applications designed to be used in concert with devices relying on multiple transport Media Transfer Protocol (MTP) or on the Windows Portable Device (WPD).

Microsoft explained that Windows 7 PCs will crash when MTP or WPD devices are connected for the first time. More »

Windows Vista includes a command line tool, Powercfg.Exe, that you can use to configure power management settings. Windows 7 introduces a new switch, /energy, to provide a comprehensive report of those settings. It also offers diagnostics that can indicate which applications or devices might be causing power management issues (such as a USB driver not entering suspend) and what power management settings you can configure differently for better results. At an elevated command prompt, simply enter:

POWERCFG –ENERGY –OUTPUT

The tool will observe your computer for 60 seconds, and then create a file called ENERGY-REPORT.HTML in the path you specified. Simply double-click on this file to see what’s going on.
