Change Password Expiry Notice Period With Regedit

My colleagues are face problem of Password expiry in windows 


because after password expiration period windows shows popup


change your password & that time my colleagues lost the password


so i am publishing this article to change your password expiry 

notice period..

In earlier versions of Windows, the default interval that


users were notified of password expiration was 14


days before expiration but in windows7 & server 2008


R2 the default password expiry notice occurs 5 days


before the password expiration date.

But Don't worry you can change it just follow the steps 

Steps:

1. open registry editor (for open registry editor goto 

    run type regedit)

2. Navigate to 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

3. At right side you will find PasswordExpiryWarning just 

double click it & change the period...

That's it now you are at secure side...
