Set the Minimum Password Length (All Windows)
Category: Home > Security > Login and Authentication
You can force Windows to reject passwords that do not meet a minimum password length. Useful to help stop people from using trivial passwords where security is an issue.
Open your registry and find the key below, if the Network sub-key does not already exist then create it.
Create a new binary value named 'MinPwdLen', and set the data to the minimum number of characters required for a password to be accepted.
Note: This does not apply to existing passwords, only new or changed.
