What I did on my Christmas holiday break 2020
Published:
I have a HP Inspiron desktop that I originally bought in 2016. It has 4GB RAM, an Intel Core i3 CPU w/ 4 cores (basically a Broadwell chip), an Intel Graphics GPU, and a Broadcom 43132 wireless card. This used to run Windows 7 fine, but with the end of support announced for early 2020, I upgraded it to Windows 10.
