This option can also be used to alter the default group configuration of a computer that has more than 64 logical processors. This option is available on bit versions of Windows 7 and Windows Server R2 and later versions. For example, the following command configures the current operating system loader to use one processor. On bit editions of Windows, applications have 4 gigabyte GB of virtual address space available. The virtual address space is divided so that 2 GB is available to the application and the other 2 GB is available only to the system.
The 4-gigabyte tuning feature, enabled with the increaseuserva option, allows you to increase the virtual address space that is available to the application up to 3 GB, which reduces the amount available to the system to between 1 and 2 GB. Windows uses the remaining address space 4 GB minus the specified amount as its kernel-mode address space. See 4-Gigabyte Tuning Windows for additional information about this feature.
When nolowmem on is specified, this option loads the operating system, device drivers, and all applications into addresses above the 4 GB boundary, and directs Windows to allocate all memory pools at addresses above the 4 GB boundary. Note that the nolowmem option is ignored in Windows 8, Windows Server , and later versions of Windows. The pae parameter is valid only on boot entries for bit versions of Windows that run on computers with xbased and xbased processors.
Hot-add memory supports memory devices that you can add without rebooting or turning off the computer. In this case, because PAE must be enabled when the system starts, it is enabled automatically so that the system can immediately address extended memory that is added between restarts.
Hot-add memory is supported only on Windows Server , Datacenter Edition; Windows Server for Itanium-Based Systems; and on the datacenter and enterprise editions of all later versions of Windows Server. For Windows Server and later versions of Windows Server, it is supported for all processor architectures. For example, the following command removes MB of memory from the total available to the operating system associated with the specified boot entry. When you use this option, Windows ignores all memory at or above the specified physical address.
Specify the address in bytes. For example, the following command sets the physical address limit at 1 GB. You can specify the address in decimal or hexadecimal 0x This option should only be used for debugging. The option is available starting in Windows 8 and Windows Server The system defaults to using extended APIC mode if it is available.
If you are setting up a debugger to debug Hyper-V on a target computer, set this option to Auto on the target computer. This command displays the active boot entries and their associated globally unique identifiers GUID. The syntax for the command is as follows:. For example, if you change the processor group option, groupsize , to a new value for testing purposes, you can revert to the default value of 64 by typing the following command and then restarting the computer.
Any change to a boot option requires a restart to take effect. DTrace DTrace. There is a bcedit option to enable dtrace. Skip to main content. This browser is no longer supported.

Tip To avoid the risk associated with using BCDEdit, consider using an alternative method to perform boot configuration discussed in this section.
