  • Hello,

    you can run a computer without a pagefile without any problem. But keep in mind that no memory dump is possible in case you'll get a blue screen.

  • Hello

    there is manage pasword in xp,so you dont have to enter credencials all the time,

    1.

    Open User Accounts in Control Panel.

    2.

    Click your account name.

    3.

    Under Related Tasks located on the left side of the window, click Manage my network passwords.

    You can now add a user name and password that you use to access a resource, or you can edit or remove an existing entry.

  • Hi,

    Please check the following guides.

    Should the pagefile be used even if I have sufficient physical memory?

  • No.  Operating Systems do not allow applications etc to point directly to physical pages, by design. The application/OS doesnt care if the page is in memory or disk etc, so what you are seeing is simply by design.  The memory manager handles this on their behalf.

    The chapter on memory management breaks it down, you might want to give it a read.

  • Yes I think.But I feel the problem arises when you want to run any application that occupies beyond the Physical memory(RAM).Until then it works fine i feel.

    Please correct me if any thing wrong.
