The registry hive and parameters deletion is easily made with desktop management software. At least it is the quickest and painless method to do that corporate-wide I know of. We have Scriptlogic's Desktop Authority tool rolled up in our environment and perform registry operations on client machines frequently. Sometimes you need to set some registry parameter to run specific software on user computer of specified user. Sometimes you need to delete key that was left by imporperly uninstalled software remotely. What's the usual, you need to change the key based on information taken from existing situation. For example, if some key exists within HKLM root create another key and set needed priviledges on that key. If not, new key shouldn't be applied because otherewise it say can lead user application to crash. That all we do through the Desktop Authority. I recommend you to try it and make your decisions.
