Downgrade from Windowa 10 to Windowa 7
I have a brand new Inspiron 3459-5025BLK All-in-one. It currently has a Windows 10 64bit OS. I like Windows 7 better. How do I install Windows 7 64bit OS,and make it work? Also, can I replace the HHD with a SSD? Is it hard to do?
Thanks

You will need to purchase a retail copy of Win 7.

Windows 7 is end of sales. There are no Downgrade Rights for the Home version of windows.

Better to stick with Windows 10 TH2. If it is the Home Edition you have no downgrade rights and need to pay full retail price to get a genuine Windows 7 license. Right click Edition and select system. It should tell you the preinstalled Edition. Also a sticker like the following should be affixed to the system:
If it is the Pro Edition you have downgrade rights.
For the actual installation you should prepare the UEFI BIOS settings and installation media in accordance to these videos.

If a Dell branded Windows 7 Professional Reinstallation DVD is used it should activate on a system with a Windows 8.1/10 Pro UEFI BIOS embedded SLP key, it will not activate on a system with a Windows 8.1/10 Home or Windows 8.1/10 Home Single Language UEFI BIOS embedded SLP key.
