Windows caches your user names and passwords entered for network shares, drives etc. That’s fine until there’s an incorrect password or username in the cache, and you want to remove it.
The utility to delete cached credentials is hard to find. It stores both certificate data and also user passwords.
Open a command prompt, or enter the following in the run command:
rundll32.exe keymgr.dll, KRShowKeyMgr
This is an excellent feature, an eye-opener for sure!
