The Windows 10 upgrade has been officially rolled out to 14 million people, and with new compatibility options for other types of operating systems like the iOS, should you bother with Windows 10 or would it be a big mistake to get it?

Users of Windows 7 and Windows 8.1 will have the option to upgrade to Windows 10 for free on their tablets, laptops, and desktop computers, but you may want to avoid it for now, according to a Newsweek report.

The upgrade will be a lot more time consuming than you might expect for one thing, with the installation taking up to an hour, meaning your computer will be useless to you if you do it in the middle of the workday for at least that long, and then you may have to spend time troubleshooting your other applications that get messed with because of the upgrade.

Then there is the fact that you can always expect bugs when a giant new upgrade like Microsoft Windows 10 gets rolled out, especially with Windows’ track record in its history. But there will almost certainly be bugs that will need to be patched, so why not wait for Microsoft to do that before upgrading?

Your system may not be completely compatible with it as well, even if it says it is. There will be new features like Cortana, Windows Hello, and Continuum that will have their own requirements that you may not meet.

Also, it’s probably best to back up your files before doing this big upgrade. Even though it shouldn’t mess with them, it always pays to play it on the safe side.

And finally, be prepared for the reality that after the upgrade, some software or even hardware like printers may stop working, and you may have to either troubleshoot them or reinstall them altogether.
