    Get the serial numbers of programs:

    If you need to reinstall your system, you will need the serial numbers of your programs. You have their installation CD but can not get their hands on the documentation containing the serial number. Do not worry, you have a second chance thanks to the software Advisor. This free little program will allow you to find, on your PC, the serial number of some of your software.
    • First of all you'll need to download Advisor and install it on your system.
    • Once installation is complete, it examines your system. After a few seconds, a web page appears.
    • In the section Software Licensing, serial numbers for software you have installed are displayed. Print the page and put it somewhere safe.

    Save the system from getting crashed:

    You can ask Windows to record in an event log, time and exact date of crashes occurring on your system. Next computers, this setting can be enabled or not be. To activate, you must edit the registry.
    • Click Start, then Run.

    • Enter regedit in the Open text box and click the OK button.

    • Pull the key from HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Control, CrashControl.

    Save the user environment after a crash:

    In most crashes, you can also save all information from the user environment: user profile, permissions, etc.. in an event log. This information can be used to investigate the causes of a problem.

    Once again, it is necessary to modify the registry to enable this setting.
    • Click Start, then Run.
    • Enter regedit in the Open text box and click the OK button.
    • Pull the key from HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Control, CrashControl.
    • Pull down the Edit menu, and click DWORD Value.
    • Name the new value UserEnvDebugLevel.
    • Double-click it to edit it. Select the category Hexadecimal Base.
    • Enter 10002 in the Value data field. Click OK.
    • Finally close the registry editor, then restart your computer for the change to take effect.

    Saving the memory in case of crash:

    When your system fails, you can create an image of the memory of your system that you can use to find the cause of the error. You can choose between several types of memory dumps.

    Complete memory: The full memory dump records the entire contents of memory before the system shuts down without explanation. Its size is equivalent to the amount of RAM installed on your computer, which you must add 1 Mo. It is therefore worth a lot of disk space to store this image. So if you have 512 MB of RAM, will dump a 512 + MB or 513 MB

    Kernel memory: The kernel memory dump records only the memory allocated to the kernel of Windows XP, hardware, operating systems and programs executed by the system. It therefore excludes the memory allocated to software executed by users. The backup process on the hard disk and is accelerated in the event of a crash. The size of the kernel memory dump is approximately one third of the total amount of RAM installed on your computer. This type of image is most interesting, since it is much smaller than the complete memory dump, and it neglects only the memory areas that do not appear to have any relation with the problem.

    Memory Dump: Finally, the memory dump records the minimum information necessary to identify the cause of the crash. The memory dump saves in less than 64 KB: the stop message and parameters, the list of drivers loaded, the process context, information on the process stopped, the information on thread that stopped.

    The memory dump can be useful if you have limited disk space. But you have less chance of finding the cause of errors in the examination, because of the lack of information retrieved.

    To set the type to create memory dump during a crash, you must change the system settings.
    • Click the right mouse button on My Computer, then choose Properties.
    • In the System Properties dialog box that opens, click the Advanced tab.
    • Then click the Settings button under Startup and Recovery.
    • Pull down list then Writing debug information, then select the type of image you want to create in a crash, Kernel memory, for example, and click OK.

    Improving the functionality of the Recovery Console:

    By default, access to all drives and all folders on your hard drive and the diskette are not allowed in the Recovery Console. Only the folder where Windows is available.

    To change this and allow you to access all folders on your hard drive and all your readers, which is convenient to perform a backup last minute of your sensitive documents, you need to change local security setting.
    • Open the Control Panel by clicking Start, Settings, then Control Panel.

    • Switch to Classic View if you're not there already, then double-click the Administrative Tools folder.

    • Then double-click on Local Security Policy tool.

    • In the Security Settings section, scroll element Local Policies, then click the Security Options folder.

    • In the right frame of the window, double-click the policy Recovery Console: Allow floppy copy and access to all drives and folders.

    • Click the Enabled option in the dialog box that appears, then confirm with OK. You can then close the Local Security Settings window.
