Choosing a Password Manager

Hello everyone,

After using Windows 10 for several months, I finally decided to search for a free password manager for my HP. Well, I am not familiar with those at all.

The question, which rise up in my head is:
If I perform a clean install of Windows 10 /which I have done many times/ with format of C:, I have to install every program all over including the considered password manager. So far nothing to worry about. But after that what passwords will or have to be used, for example, for Google account, Facebook or Windows10Forum, etc. Are they the same as when they were created by me or randomly generated by the password manager?

Sorry, if I am not very clear but it is confusing for me. Once again in other words:

Will a future reinstall of Windows 10 and following reinstall of all programs, including a password manager, affect the passwords which I have now on a piece of paper? Which free password manager would you suggest?

Thank you all, will appreciate every opinion.

I use KeePass 2 for my password manager.

Ditto on Lastpass here. They have an add-on for all major browsers incl Edge. Besides the random password generator, you can choose to auto login or, for extra security (say, on your bank site), prompt for master password before filling in user name and password.

Thank you all for the advices!

Use keepass, it is freeware and you can get firefox add-on (keefox) which fills in automatically the logins on web-pages if u like.
Else you can manually insert the login information with a few clicks from Keepass.
It saves your passwords in an encrypted file, which you can save wherever you want to, and when you re-install Windows/Keepass, you just import that password file back into it.

There is also a portable version of Keepass,which you can carry around in your usb hard-drive or pen, and
run it on any computer.
