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.

REGISTRY SETTINGS:

User Key: [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\
Network]
System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\
Network]
Value Name: MinPwdLen
Data Type: REG_BINARY (Binary Value)

The good thing is it works for all versions of windows
