Ignore errors produced when clicking on the Copy button - they simply mean that the tool could not create the backup files for some reason. The data is still copied to the clipboard for pasting to your response.

Please also state the Version and Edition of Windows quoted on your COA sticker (if you have one) on the case of your machine (or inside the battery compartment), but do NOT quote the Key on the sticker!
