Hello, DucksooKim
Thank you for visiting the Microsoft Community.
I have aquestion about password change cycle while using Windows 10.
Please login as administrator and proceed as follows
Click [Windows Logo Key + R], enter gpedit.mscin the execution window, and click OK.
**Select [Computer Configuration - Windows Settings - Security Settings - Account Policies - Password Policy]**to set the "Maximum password age".
gpedit.msc isonly available for Windows 10 Pro or later.
The following table lists the actual valid default policy values.
I hope you have a good day today, hoping that your answers have been helpful.
