Create a system backup within Windows 7
Windows 7 (and Vista) have an option to create a system image backup. Click on the Start Menu and type “backup” in the search dialog box. Select the Backup and Restore menu item.
Click on the “Create a system image” option.
It is easier to create a system image using an external USB hard drive. If you have one connected, select the device under the hard drive drop-down box. Click on the Next button once a selection has been made.
Once selected, click on the “Start backup” button.
A dialog box should appear displaying progress of the backup.
A dialog box will appear asking if you wish to create a System Repair disc. You can create one now or later.
Once a decision has been made concerning the System Repair disc, the final dialog box should be displayed.
Trigger services within Windows 7
Windows 7 includes a new type of service called trigger. A trigger-start service is a regular service that you can configure to run (or stop running) only when certain criteria and conditions that you define are met. Some conditions would be:
Device arrival or departure
Joining or leaving a domain
Opening or closing a firewall port
Group policy change
To view trigger information, use the sc command with the parameter of qtriggerinfo.
Certain services will not have any triggers present.
