    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

    -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
    -Click OK.
    -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
