You don't need admin access to do a lot of damage on a windows system. From the user space, a malware can:

  1. Exfiltrate files
  2. Read memory of other processes
  3. Read all user credentials from the credential store, including from TPM
  4. If the malware can fool the user to authenticate using Windows Hello, even the password managers that store encrypted secrets in credential stores aren't safe:

See this same class of malware at (unfortunate link, but you can see the detailed discussions there): https://www.reddit.com/r/Bitwarden/comments/14r29p6/meduza_stealer_will_steal_on_windows_browser/
