Any new laptop but ask for Windows 7.
Windows 10 comes pre-installed with many shitware that will slow down your pc.
The last thing you should be running is Windows 7. Windows 10 comes with a surprisingly low amount of bloat. Of course, your mileage will vary depending on the machine manufacturer. The only downside to Windows 10 is privacy. Saying that, if you use anything by Apple, Google or Facebook, youve already sold your soul.
