There are many ways to manage your Internet Explorer passwords. The tricks below should also work for newer Windows versions as well.
1) Use registry to export the entries
Open regedit and browse to Computer\HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\SPW. You will see a list of encrypted password entries in the right column. Click on File -> Export to save the contents to a .reg file. Proceed to import this on your new PC.
2) Use the Windows Credentials Manager
Open Control Panel and go to User Accounts -> Credential Manager.
Your IE saved passwords will be available in the Web Credentials tab.
3) Export/import with credwiz.exe utility
Open the Run prompt by pressing [WIN]+[R] buttons, type credwiz.exe and press the ENTER key.
Follow the instructions in the wizard.
4) Use NirSoft’ IEPassView
Download IEPassView from http://www.nirsoft.net/utils/internet_explorer_password.html and follow the instructions. This will also decrypt and show you the passwords in clear text.
IEPassView can also decrypt the passwords from an externally mounted harddrive.
Please also consider migrating to a dedicated password manager like KeePassXC
