Administrator rights

If the following error occurs:
"The boot configuration data store could not be opened. Access is denied.",
you need to run cmd as an administrator, and then repeat the above instructions.

set autostart

@echo off

REM 检查参数是否为空
if "%1" == "" (
bcdedit /set increaseuserva 4096
exit /b 1
)

REM 根据参数值执行不同的命令
if "%1" == "0" (
    bcdedit /deletevalue increaseuserva
    if %errorlevel% equ 0 (
        echo delete succeed!
    ) else (
        echo delete error
    )
) else if %1 GTR 1024 (
    bcdedit /set increaseuserva %1
    if %errorlevel% equ 0 (
        echo set succeed!
    ) else (
        echo set error
    )
) else (
    echo error: %1
    exit /b 1
