So, I made an exported image of my registry.
Then, I then opened the file with Notepad.
Next I did a global search and replace of C:\Windows\Installer to T:\Windows\Installer.
Note the need for two backslashes as I discovered the correct format is C:\\Windows\\Installer. So the above entries would be C:\\Windows\\Installer to T:\\Windows\\Installer
There are hundreds of entries and thus a one-by-one search and replace with Regedit would be too tedious and time consuming and fraught with possible typos.
Now, before I pull the trigger and import all these amended keys, in actuality the entire registry I need to ask a few questions.
Yes, I have moved the folder as a test to the target location.
Besides Regedit and this global search and replace followed by an import, is there another way.
No I cannot clear C:\Windows\Installer as the uninstaller uses this folder when a program is being removed.
Do you think I’m nuts, rhetorically of course?
