If you thought Windows 10 was going to be a great thing but just don’t get it or like it, you can undo it! To avoid reinstalling Windows 8.1 or 7, you just have to undo it within 30 days of the upgrade. Here’s how: click on the Start icon, click Settings, click Update & Security, click on Recovery in the left column. Then click on Go back to Windows 8.1 (or 7 if that is what you had), fill in the reason you are going back, make sure your computer is plugged in if it is a laptop, click another next button and wait. When your computer restarts, you should be back where you were, minus any software you installed in Windows 10. There is the slight possibility you might have to reinstall or reactivate some programs.
Here are some tips for using Windows 10: if you can not get used to Microsoft’s new web browser, called Edge, you can always install Firefox, www.firefox.com, or Chrome, www.chrome.com (click on the download link at the top of this page) and then you can ease into playing with Microsoft Edge, rather than being frustrated with something new that does not work the same as Internet Explorer. And, you can still get that Windows 7 feel by installing Classic Shell from <www.classicshell.net>.
If you are worried about malware on your Mac, Malwarebytes has software for you at <https://www.malwarebytes.org/antimalware/mac/>. Currently this is a free application, but you have to run it manually each time you want to scan your computer. Expect a paid version at some point, for it to be always on and running in the background.
Microsoft has a new update delivery method; it will now use other computers on your network and the Internet to deliver parts of updates to your computer, to spread the load around the Internet. If you have a limited data connection, like a cellular hotspot, then you will want to turn this off. Click on Start, then Settings, Update & Security, Windows Update, and then Advanced options. Select Choose how updates are delivered, and then slide the toggle to turn Delivery Optimization off. When turned off, you’ll still get updates and apps from Windows Update and from the Windows Store. If you’d just like to stop downloading updates and apps from PCs on the Internet, select the option for PCs on my local network.
Data backup and redundancy sound similar in how they protect you but a backup is no good if it is the only copy of your data and it sits on a hard drive right next to your laptop, all scooped up by that enterprising thief. Redundancy means that you would have had another copy in another location; either using a cloud-based backup service or physically taking backup drives off-site. You should avoid having any single point of failure. Similarly, if your Internet connection must always be there, then you should think of having an alternative, maybe setting up your cell phone as a hotspot.
