如下是源码，其实在98上只用最后一句ExitWindowEx即可，前面是为了取得权限.

TOKEN_PRIVILEGES tkp,tkpNewButIgnored;

HANDLE hdlTokenHandle;

LUID tmpLuid;

BOOL rc;

DWORD lBufferNeeded;

HANDLE hdlProcessHandle = GetCurrentProcess();

rc = ::OpenProcessToken(hdlProcessHandle,TOKEN_ADJUST_PRIVILEGES|TOKEN_QUERY,

&hdlTokenHandle);

rc = LookupPrivilegeValue("","SeShutdownPrivilege", &tmpLuid);

tkp.PrivilegeCount = 1; // One privilege to set

tkp.Privileges[0].Luid = tmpLuid;

tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

rc = ::AdjustTokenPrivileges(hdlTokenHandle,

FALSE,

&tkp,

sizeof(tkpNewButIgnored),

&tkpNewButIgnored,

&lBufferNeeded);

ExitWindowsEx(EWX_REBOOT,0);
