On C I only have my windows OS , data is on D. I think that should be enough precaution? If course I backed up everything but I don’t plan on backup everything again. Or do you think it could “leech”?
I made sure that only the OS is on C. That’s my MO since I had some bad experiences concerning windows installations (my first PC was running Windows ME)
I read a bit into bitwarden and it seems quite good, also with browser extension etc. Maybe I will think about my stance on password managers and give it a try
