Windows 7 Feature Focus: Recovery Environment
Sending Your System "Back, Back in Time," with System Restore
System Restore has always been a useful way to solve system problems caused by faulty hardware or software installations. Windows Vista's Recovery Environment was the first to permit you to run System Restore without starting Windows first, and Windows 7 adds more refinements.
When you select System Restore from the System Recovery Options menu, click Next on the opening dialog (1) to continue.
By default, Windows 7 shows you only the most recent restore point, because in many cases, that's the one you'd use. If you've been having problems for awhile, you can see additional restore points by clicking the empty Show More Restore Points box. When this box is checked (2), you can scroll through the restore points to select the one you want to restore.
Windows 7 adds an important new feature to System Restore: the ability to see what will be changed on your system when you revert to a particular restore point. To see this information, select your preferred restore point and click the Scan for Affected Programs button (arrow).
The top pane of the dialog shows you the programs that will be removed, and the bottom pane shows you the programs that will be restored; usually programs that were replaced by newer versions. In this example, Microsoft Silverlight 3.x (top pane) would be removed, and the older Microsoft Silverlight 2.x version (bottom pane) would be restored. However, restored programs might not work. Use this dialog as a guide to determine what programs you might want to reinstall after reverting your system. Click Close to return to the main dialog. When you return to the main dialog (3, previous figure), click Next to continue.
Make sure the restore point you want to use is displayed (4), then click Finish (5). Note that you have one more chance to view affected programs (arrow).
When the system reboots, it will have been reverted to the restore point you selected.

Testing System Memory with Windows Memory Diagnostic
Windows Memory Diagnostic, which is based on Microsoft's downloadable memory test, was also found in Windows Vista's Recovery Environment. When you select the Windows Memory Diagnostic link from the System Recovery Options menu, you can choose whether to restart your system and run diagnostics now (default) or test memory the next time the system is rebooted.
When the system restarts, the memory diagnostic tool runs. By default, it runs twice, then reboots the system and displays any detected problems after you log onto Windows. To change or review settings, press the F1 key (arrow).
The default test set is Standard (1); other options include Basic (fewer tests) and Extended (all tests). Some tests disable memory cache, while others enable it (see the description for each test set for details (2). To adjust the cache settings, tab to Cache (3): and select the settings desired. To adjust the number of test passes, tab to Pass Count (4): and enter the number desired. Press F10 to save changes.
