Explanation:
You can open Device Manager on a computer running Windows 7 while logged on with any account. However, by default, only administrators can make changes to devices and install, uninstall, and roll back drivers. You can open Device Manager in the following ways:
- In Control Panel, click Hardware And Sound. Click Device Manager under Devices And Printers.
- Click Start, right-click Computer, and choose Manage. Click Device Manager in the Computer Management tree pane.
- Open an elevated command prompt and enter mmc devmgmt.msc. Note that if you do not run the command prompt as administrator, Device Manager opens as read-only.
