Fix 8: Switch khổng lồ ChromeOS

*

Windows is a very old technology. Sure, Windows 10 is relatively new, but it’s still just the latest iteration of a decades-old operating system, designed for a bygone era (pre-internet).

Now that we have the internet, fast connection speeds, free cloud storage, & endless web apps (like Gmail, Google Docs, Slack, Facebook, Dropbox và Spotify), the entire Windows way of doing things – with locally installed programs and local tệp tin storage – is totally outdated.

Why is that a problem? Because when you’re constantly installing uncontrolled third-party programs, you’re constantly opening the door lớn viruses & other malware. (And Windows’ insecure permission system compounds this problem.)

Plus the way Windows manages installed software and hardware has always been a problem. If your computer shuts down unexpectedly, or a program installs, uninstalls or updates incorrectly, you can get ‘registry’ corruptions. That’s why Windows PCs always slow down & become unstable over time.

Also because everything’s installed và saved locally, it doesn’t take long before you run out of disk space, and your disk gets fragmented, which makes everything even slower & more unstable.

For most people, the simplest way to solve Windows problems is to ditch Windows altogether, & switch to lớn a faster, more reliable, more secure, easier khổng lồ use và cheaper operating system…

Google ChromeOS.

ChromeOS feels much lượt thích Windows, but instead of installing heaps of programs khổng lồ email, chat, browse the internet, write documents, bởi school presentations, create spreadsheets, và whatever else you normally do on a computer, you use website apps. You don’t need to lớn install anything at all.

That means you don’t have virus & malware problems, & your computer doesn’t slow down over time, or become unstable.

And that’s just the start of the benefits…
