Microsoft: Windows 8 has seen 60 billion hours of use since launch

In May, Microsoft announced that it had sold 100 million Windows 8 licenses since it launched in October 2012, which it said was on a par with sales of Windows 7 during the same time period. Today, as part of the 2013 Microsoft Worldwide Partner Conference, Windows marketing head Tami Weller repeated that statistic but also offered two other bullet points on Windows 8.

As part of her keynote speech at WPC 2013, Reller said that so far, Windows 8 has seen 60 billion hours of use since launch. While Reller didn't offer any comparisons to earlier versions of Windows, 60 billion hours of anything certainly sounds like a lot.

Reller also said that so far, there have been 20 million evaluations of Windows 8 in the enterprise market. Again, she did not offer any information on how those compare to Windows 7 in the same launch time period, but it seems that more and more businesses are moving toward Windows 8, especially given that, in less than a year, Microsoft will end official support for Windows XP.

Finally, Reller said that new customer activations of Windows 8 have continued "at a consistent pace". Earlier this month, data from Net Applications showed that the PC market share for Windows 8 has now surpassed that of Windows Vista.

Well, considering that windows 7 hit 100m licenses sold around apr 23 and windows 8 hit 100m licenses sold around may 7 and that windows 8 was available for release to the general population on oct 26, about a week after the release of windows 7, I'd say windows 8 is doing pretty well.

Stop it. Just stop it. We don't use real facts here. Windows 8 is a failure.

Here come some inflammatory posts by Chrome OS and OSX trolls

/s on the Chrome OS trolls. I can't believe I see these at my local future shop, what a waste.

Well compare that to XP's trillions or gazillions of hours of usage. Rude reimagination of software is rude. And calling it a fear of change instead of respecting the users' preference is even worse.

Plenty of stats to compare:

60,000,000,000 hours spread across 120,000,000 licenses / evaluations works out to 500 hours each license, 600 hours if you leave off the evaluations. This equates ~2-3 hours a day, every day since release. If one assumes 1/2 of the licenses are sitting on shelves waiting to sell, that's ~5-6 hours a day, every day since release.

Or (and dependent on what "use" actually means, ie does an active virus scan count? Background processes?)...

It's 7/8/13, so Win8 has been commercially available since Oct 26th which is 255 days.

255 days x PC "used" avg 24 hours a day = 6120 total hours per PC. 60 billion / 6120 = 9,803,921 PCs
255 days x PC "used" avg 12 hours a day = 3060 total hours per PC. 60 billion / 3060 = 19,607,843 PCs
255 days x PC "used" avg 6 hours a day = 1530 total hours per PC. 60 billion / 1520 = 39,215,686 PCs
255 days x PC "used" avg 3 hours a day = 765 total hours per PC. 60 billion / 765 = 78,431,372 PCs
255 days x PC "used" avg 1 hours a day = 255 total hours per PC. 60 billion / 255 = 235,294,117 PCs

@Condere You are assuming all licenses contributed equally which doesn't make sense. If you made a graph that depicted hours spent using windows 8 per day it wouldn't be a flat horizontal line but one with a positive slope.

avg == average

Definition of AVERAGE (per Miriam-Webster)

1 a : a single value (as a mean, mode, or median) that summarizes or represents the general significance of a set of unequal values


BTW, per my first post, you know what else doesn't make sense?

Used... what does that mean? How do they know when and for how long a person uses their PC. For instance, I'm reading through a training manual in another window right now.

It takes... I don't know... a minute or two to get through each page. Between scrolling down to each page, all I'm doing is reading the page with no I/O inputs. I'm using the PC, but I'm assuming MS has no clue that I am since I am not moving a mouse nor pressing any keys, or touching the screen.

So it is very popular with tablet and touch-screen laptop users. In other words, gamers and consumers. It says little, or nothing, about how it is being used on non touch-centric laptops and desktops.

Windows 8 is by far the biggest os failure in the entire history of microsoft far surpassing their previous failures Vista and ME, microsoft should just accept the fact that they made a colossal mistake and move on instead of wasting resources posting heavily flawed and shady claims of an invisible success.

Maybe the 60 billion hours of usage is to suggest that perhaps they know somewhat more about how people use Windows 8 and its usability than the commenters here.

Benchmark please. This absolute number is totally useless unless there is something to compare it with. So:
- How many hours has Win 7 had?
- How many for Win XP? Vista? Win95?
- How many for iOS? Linux?
Without a comparator, the quoted number is meaningless.
And of course, the unanswered question is how many hours were enjoyable and how many were misery? How many hours of Win7 use post-Win8?
