|If your computer is older and running Windows 7 or earlier a new computer most likely wont run programs in Windows 10 or 11. You will have to download and install current versions of the ones you want to use. |
To transfer data (documents, photos, music and videos etc.) simply buy a flashdrive large enough to hold it all and copy each folder into the My Documents folder on the new computer.
By the way most new computers don't have a true hard drive in them, it will have a SSD, Solid State Device, no moving parts, faster and more reliable. Last new computer I bought for home has a 1TB SSD and I added a 5TB true hard drive to act as storage for photos and other documents.
