How separate are Windows user profiles?

ThePrivacyDad: > When I install something on a second user account, then I am asked for the admin user’s password. Would doing this give linewize access to all accounts? During installation, yes. With which privileges it runs after installation is a different question. But considering its purpose, it likely runs with the necessary privileges to have cross-profile access. Recommend not installing it. ThePrivacyDad: > r/privacy Not a good source of information. I would recommend to edit your answer there.
