Windows 10 running slowly on laptop?

Yes my laptop Hp625 has been running very, very slowly since I have Windows 10. On January 14th I changed immediately because of Wind7. What can I do there? Should I get Windows 8?

Install an SSD then it runs. Don't expect too much.

Windows 10 has the same system requirements as Windows 7 and usually runs even better. You should clean up your computer: clean disk, defragment hard drive…

The thing is extremely old.

Try an SSD and at least 4GB RAM.

What have you installed? Intel DualCore or AMD DualCore Athlon?

Windows 8.1 will probably run even worse.

Above all, reinstall Windows 10 and do not use the Windows 7 to Windows 10 update.
