  Removing an ECO kit? 
 The Question is:
 
How do I remove a patch that was previously installed in the system? I am using
 a Alpha1000 server with OpenVMS v7.1-H2 and the command which I install the
 patch was @sys$update:vmsinstal &lt;kit&gt; &lt;kit location&gt;
 
 
 
 The Answer is:
 
  Either through (if provided) a drop ECO procedure or through the
  restoration of a BACKUP made prior to the application of the ECO.
 
  Though please move to OpenVMS Alpha V7.1-2, and please move off of
  OpenVMS Alpha V7.1, V7.1-1H1, and V7.1-1H2 -- V7.1-2 includes a new
  mechanism for ECO kits (PCSI), as well as also including a number of
  updates and ECO kits that target these older releases.
