If you have ever right-clicked a file on Windows 10 or 11, selected "Send to," and chosen "Compressed (zipped) folder," you have likely noticed something frustrating: there is no option to set a password.
It is a common misconception that the standard Right-click > Send to > Compressed (zipped) folder option in Windows allows you to set a password. It does not.

WinRAR is another popular file archiver that allows you to create and extract ZIP files, as well as password protect them. Here's how:
Historically, Windows XP included a native ability to password-protect ZIPs, but Microsoft removed this capability in later versions due to security concerns and a shift toward their proprietary encryption standard, EFS (Encrypting File System).
This method only locks the file to your Windows user account. If you send this file to someone else via email, the encryption strips away automatically, and they will be able to open it. It is strictly for local security.
