To restore your computer back to factory settings, follow the steps below:

• Turn on the computer and keep tapping F8 until the advanced options menu is displayed.

	Use the up/down arrow keys on the keyboard to highlight Repair Your Computer and press enter to select it.
	Choose the appropriate language you wish to install.  For UK machines there will be no other language pack installed and you will not see this screen at all.  Nordic & Central European machines will have multiple languages available.
	Once you have chosen your language you will be presented with the available recovery options. Microsoft Repair Environment - after choosing the UK keyboard layout you will be asked to choose the Operating System you wish to repair.  If Windows Vista is not listed then you cannot repair the OS without doing the full recovery.  After choosing Vista the Microsoft Vista startup repair tool will run and attempt to repair any startup problems you are experiencing. Reinstall Windows - gives you the options available to reinstall Vista Advanced Options - this launches the diagnostic centre allowing you to run chkdsk, launch notepad or bring up a command prompt. Exit & restart computer - exactly as the name suggests. To continue with the recovery program you need to choose Reinstall Windows.
	From this screen you have the ability to launch Vista System Restore and roll back to a date when Vista was last working ok or to run the Full Destructive Recovery.  To continue with the recovery program you need to choose Start Full Destructive Recovery.
	After choosing the Full Destructive Recovery option you are presented with the warning screen that all data will be lost.  It is important to make sure all data has been backed up to disk if possible and to realise this process deletes all data and reverts the machine back to it's default state. To continue with the recovery program you need to tick the box indicating you are aware of data loss.
	Once you have started the process the recovery completes the following steps: Prepares the hard disk by formatting the partition with the NTFS file format Extracts and installs Vista onto the newly created partition from the files on the recovery partition Finalises the process making Vista bootable so the final stages of the recovery can be completed .
	On first restart the recovery program spends time detecting the hardware in the computer and generating the necessary hardware id's for licensing purposes.  This process may take some time depending on the speed of your computer.  Please be patient and don't restart the computer as you will have to start the recovery process from the beginning again.
	The next stage is the Out of Box Experience (OOBE).  Complete this stage making the appropriate choices. See the separate OOBE guide for further information and screenshots.
	Following it's completion a final restart will bring you to the desktop and the Welcome Center.  From the welcome centre you can view details about your computer, customise it's appearence, add new users, upgrade to a different version of Vista, view the manual for your computer and many other useful tasks. Note  By default the Welcome Center is shown at every startup - to stop this behaviour remove the tick from the bottom of the Welcome Center window.  You can return to it at any time from control panel.
