I want to delete my account completely so how can I do this?
I want to completely remove it from my laptop.
You can't specifically delete an account on the Adobe website. You can uninstall all Adobe apps from your computer using either the Windows Uninstall programs system or whatever you do on a Mac and or from the CC DTA and then run the CC Cleaner tool to wipe every trace out.
Then Never come back to this forum, Never log into anything Adobe and never go to the Adobe home page.
Account will basically be inactive.
