@info That all depends on the compatibility of the hardware and drivers.  That's why Microsoft runs a series of compatibility tests on the PC before installing the upgrade.

One of my laptops had just one compatibility issue and I ended up scraping the whole thing knowing January 14, 2020 is the official EOL date for Windows 7.

But if your PC is compatible and hopefully exceeds the basic requirements or could be upgraded, you may not want to write that off just yet.
