Windows 7 default username limitation of 20 charaters RRS feed

  • Question

  • How do you override Windows7 Default UserName limitation of 20 Charaters? I need to create accounts larger than 20 charaters, put no more than 64. The Windows7 Workstations are not presently membered in AD. I know that AD will resolve this problem, but would like to work around limitation without having to rely on AD.

    Thanks,

  • As I know, there is no GUI configuration to get pass the 20 characters. Maybe you could program a codec to achieve this. I would like to recommend you to post in MSDN forums to get some help.

  • Hi,

     

    Thanks for posting in Microsoft TechNet forums.

     

    No. It is fixed at 20 characters for the local username. This is by design regarding the backward compatibility reason. You may name in AD to get pass the 20 charators.

     

    Reference:

    2.4 String Field Length Limits

  • Hi Dale,

    You mention that I could "name in AD" to get pass the 20 characters. I am not sure what you mean by (name in),  or are you referring to adding the workstation to Active Directory? I was hoping to find an alternate solution to getting around the limitation other than adding to a domain. It seems a local group policy or modification to the registry would be available.

     

    Thanks again for your response.
