Windows 10: How do I change Max Memory now?

    How do I change Max Memory now?


    My pc was only using around 1.98GB or the 4GB of ram that I have so I decided to go into the msconfig and change it like I did on the pc I had before. But this time I made a mistake. I believe I set the Max Memory to 0 because it now takes my computer a very long time to start up. I'm wondering if anyone could help me find a solution, such as how to system restore or fix it in the BIOS?

    Thanks,

    Hello Hanable, and welcome to Ten Forums.

    Other than changing it back after Windows finally starts up, or you could do a system restore at boot using a restore point dated before you made this change to undo it.

    When you boot Windows USB - go to Repair - Troubleshooting - CMD - try to run those:
    Code:
    bcdedit /deletevalue {current} removememory
    bcdedit /deletevalue {current} truncatememory
    bcdedit /deletevalue {default} removememory
    bcdedit /deletevalue {default} truncatememory
    When you enter just "bcdedit", you should actually see, what setting is used as well as your identifier.
    Code:
    bcdedit /deletevalue {identifier} removememory
    bcdedit /deletevalue {identifier} truncatememory

    So I need to boot windows to get to this or can I do it from the BIOS?
    And thank you both for such a quick response

    If you still can boot into windows then just open the admin command prompt and type:
    bcdedit /deletevalue {default} truncatememory

    Then reboot

    FYI, You should leave everything unchecked from msconfig.
    Windows default is to use max values available.

    You can boot Windows Setup from USB/DVD without booting Windows and open CMD from there.

    To add, use the Command Prompt to Run as Administrator. Start, W section, System, right-click Command Prompt and Run as Administrator. Once it is open, showing on the Taskbar, I like to right-click that icon and Pin to Taskbar. PowerShell is the replacement and I'm trying to learn it but the familiar things tend to work faster for me.
