Windows 10 was released this week, to much fanfare.
Some people love it, and say that it's a great upgrade to the operating system. Microsoft itself is trumpeting that more than 14 million computer users were running Windows 10 within 24 hours of its release.
But I think it might be wise for many computer users to wait before upgrading.
Remember, until July 29 2016, Windows 10 is a free upgrade if you currently use Windows 7 or Windows 8. After that date you will need to pay the regular retail price if you want to switch. So you don't have to upgrade right now.
Your Windows 7 and Windows 8 computers are still receiving security updates, and if those versions of Windows are working well for you there's no *need* to upgrade just yet.
Sure, many people are saying that Windows 10 is a slicker version of the operating system than some of the releases that Microsoft has issued in recent years - but if it ain't broke, why fix it?
Instead, let millions of other Microsoft Windows users upgrade before you.
See how they fare, and give Microsoft time to iron out any wrinkles like the autoupdating Nvidia graphic drivers that were breaking Windows 10 installations earlier this week. That issue was reportedly fixed just before the official release of Windows 10, but no-one can be sure right now just how many other serious bugs might be lurking.
Then, when you're ready, if you have more than one computer, try upgrading to Windows 10 on one of them - and trying it out for a while, before installing in all of your PCs.
Having a little patience, and waiting a few weeks before upgrading your PC to Windows 10, might be a wise choice.
One more thing - and this is my message to those of you lurking in the corner trying to hide the fact that you're still using Windows XP.
If you are still running Windows XP at home (or inside your organisation) then there's no free upgrade to Windows 10 available to you. It's quite possible that your computer hardware isn't even capable of running Windows 10.
If that's the case then don't shrug your shoulders and ignore the hullabaloo about Windows 10. See the release of Microsoft's new operating system as a good time to reconsider your decision to stick with Windows XP. Because Windows XP is dead as a dodo, and has not received any security patches for a long long time.
If you care about your computer security and privacy, it may make sense to dump XP and either switch to an alternative OS or get a new computer which can run Windows 10.
