title: upgrading powershell breaks it
body: <p>I recently upgraded powershell using choco.</p>
  
  <p>It looked like everything went fine, but now, I can't even open it anymore.
  Whenever I try to run it, it just starts tons of powershell.exe processes that I can see in the task manager, and takes all memory.</p>
  
  <p>I can't try to install another version of powershell, because <a href="https://docs.microsoft.com/en-us/powershell/wmf/5.1/install-configure#install-wmf-51-for-windows-server-2008-r2-and-windows-7" rel="nofollow noreferrer">I need a working version of powershell to do so</a>, and I do not have one.</p>
  
  <p>EDIT:
  As suggested in comments, I could start powershell from the cmd.exe using -noProfile option. But now it says powershell is already up to date. Does it means I will have to get back to an old powershell version?</p>
  
  <p>What can I do?
