Windows 7 has a number of troubleshooting tools built into it, which can be real help when things are not working correctly.
The tools can be accessed in two ways. You can click on the Start button (the Windows Orb) > Control Panel > System and Security. Then, under the Action Center heading, click on Troubleshoot common computer problems.
Alternatively, you can click on Start, and type troubleshooting in the search box, and select the Troubleshooting entry it finds.
Either way opens the same troubleshooting dialog box:
Although this dialog box looks similar to the main control panel dialog box, these options do not let you make changes to Windows settings. These are links to troubleshooting wizards in Windows.
As usual, the headings (Programs, Hardware and Sounds, Network and Internet, Appearance and Personalization, and System and Security) are links themselves, and link to more functions than the few shown on the this dialog box.
For example, if you click on System and Security, you’ll get a different dialog box that’s formulated more as a list that include these options and more. The other headings have similar lists.
For this example, I clicked on the link to the Power troubleshooting wizard. Although phrased differently, this link takes you to the same Power troubleshooting dialog box as the "Improve power usage" link on the dialog box.
As you can see, there’s not much on the starting screen of the wizard — not much other than a crucially important link labelled "Advanced."
As I also found out the hard way, the default setting in the wizards is to automatically make the changes it wants to make. This changed my carefully set power options on my desktop, without asking.
The only option on the Advanced link is the option to uncheck (checked by default) the "Apply repairs automatically" checkbox.
This taught me that the troubleshooting wizards are easy to use, but that I wanted to see the changes they would make before allowing the changes to be made.
