Lost licence information for Adobe and Microsoft Accounts

When I run CCleaner in custom clean mode, I usually have to re-enter my password etc for both my Adobe CC and Microsoft Office accounts afterwards. I think it must be deleting key files on my C drive which record my licence details, but I cannot find the affected files. For Adobe, this is an inconvenience (I use 2 stage verification, so it also requires a code from my phone). For Microsoft (predictably) it is more involved, requiring several sign ins, something about logging into Microsoft Home (I think that's the right title) which I cannot get to work, and re-entering my Google email details for Outlook.

Can anyone help please?
