I am attempting to standardize our PowerShell deployment and usage across all servers, which involves uninstalling PS1.0/installing PS2.0 on Server 2003 machines. In searching for KB926139 through CMD and Control Panel Add/Remove Programs, it is nowhere to be found. We have KB926141 installed on these servers as the Language Pack update, but no initial Install Update.

PowerShell 1.0 is installed on the server and can be found at the default locations (%windir%\System32\WindowsPowerShell\V1.0, %windir%\Syswow64\WindowsPowerShell\V1.0).

I would like to avoid deleting the Registry Entry in this situation since it should be pretty simple, any help would be appreciated. Thanks!


Ddono25, You could use PSEXEC to execute a remove/install script against a list of hosts. Do you need help with something to remove the files?

  • That looks like it would be possible. I guess I am not understanding why the update is not present. – Ddono25 Jan 10 '11 at 23:04
  • From cmd.exe execute wmic qfe list full |findstr "KB926139" or wmic qfe list full /format:htable > c:\tmp\output.html to print the whole list of KB's installed to a nice pretty HTML table. – Eric Jan 11 '11 at 2:11
  • My comment got a bit messy there; if you run that string then it should tell you if the KB is installed, and the details along with it. – Eric Jan 11 '11 at 20:26
