The Reg.exe utility does not compress a registry key when the utility saves a registry key to a hive file


View products that this article applies to.

Symptoms

Consider the following scenario:
  • You try to make copies of the registry or of the registry keys on a computer that is running one of the following operating systems:
    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2
    • Windows 8
    • Windows Server 2012
  • You use the reg save command to export the registry key into a hive file.
In this scenario, the reg save command does not compress the registry key during the exporting process. Therefore, the size of the hive file may be larger than expected.

Resolution

A hotfix is available to resolve this issue. After you install this hotfix, you can use the /c switch in the reg save command to compress the registry key. For example, the following command compresses the HKLM\System subkey:
reg save hklm\system %windir%\system32\config\system.lkg /y /c
