Some customers reported that they got error 0x80080005 on their WSUS client. A simple fix is adding the following registry key:


Key = RegistrySizeLimit

Type = DWORD

Value = 4294967295

    No need to edit registry. Give "Everyone" permission. When done. Remove "Everyone" permission. Worked for me.

    Hi Sanju, you need to use decimal on the left, or you can type in ffffff for hexadecimal.

  5. Polar says:

    Sorry I mean decimal on the right or 8 f for hexadecimal.
