Aternity Digital Experience Insights Windows Reliability

Amir Straus August 6, 2018

Everyone has an experience with Windows reliability. As is the case with many things, we mainly remember the negative ones. Doesn’t it seem that your PC is slow to boot up just when you’re running late to a meeting you’re hosting? Does your colleague complain frequently that her laptop shuts down during a key presentation after only a few minutes on battery power?

If you’ve ever wondered about how your organization compares when it comes to the reliability of Windows computers, this analysis from Aternity has some answers. Its conclusions are based on real data from over a million desktops, laptops, and tablets from hundreds of companies around the world being monitored by Aternity running in the cloud. Aternity presents an accurate picture of cross-enterprise Windows Reliability, because our SaaS-based product monitors performance from the end user viewpoint, in companies of all sizes across multiple industry sectors. This perspective enables Aternity to provide insight into factors affecting digital experience, such as Windows reliability.

Aternity equips desktop services teams to identify and resolve device health and performance issues, proactively, remotely, and non-invasively. This enables IT to get out in front of issues affecting Windows reliability, improve end user satisfaction scores, and reduce trouble ticket volume and Mean Time to Repair. And Aternity provides the same type of capabilities for enterprise Mac environments as well. Watch this short video to see Aternity in action.

An introduction to Windows Reliability Monitoring

First, let’s review Windows Reliability Monitoring. Though reliability seems like a subjective concept, Microsoft uses the Windows Reliability Monitor, part of the Microsoft Management Console to do this. The Windows Reliability Monitor measures OS, applications, and hardware issues, and converts the results into a score, ranging from 1 (terribly unstable) to 10 (amazingly stable). Windows compiles the monitoring results over time. Trouble-free operation raises the score, and errors or failures lower it. Of course, there are many factors involved, such as type of device, version of Windows, what drivers are common on the devices, and so on.

You can see the reliability score of your own computer by typing “Reliability” in Windows Search, and clicking View reliability history. This opens the Windows Reliability Monitor, which presents a blue line tracking the score of your Windows computer, along with a history of the events.

The blue line rises and falls based on the cumulative reliability of the device over the lifetime of the system (or since the Windows Reliability Monitor was reset by the user). Recent events, or lack thereof, are weighted more heavily in calculating the score.

Aternity customers can view the Windows reliability statistics of devices running Microsoft Windows OS across your enterprise in the Desktop Reliability dashboard (learn more):

Windows reliability insights with Aternity

As part of our Digital Experience Insights series, we compiled Windows reliability data over a two week period from about a million Windows devices running various versions of Windows 7, 8, XP, and 10. As a SaaS platform, Aternity monitors these machines across various countries, industries, and companies. The results below are derived from this aggregated reliability data.

As shown below, overall Windows reliability is fairly strong. About 25% of monitored devices have reliability scores of 5 or below. And over half of the devices had grades over 7.

Comparing the reliability of laptops and desktops

Aternity monitors every type of Windows device in the enterprise—laptops, PCs, tablets, smartphones, and virtual devices. We analyzed the reliability scores for the different types of computers. We found that although laptops are convenient, they’re about 10% less reliable than desktops.

Laptops have Windows reliability scores about 10% lower than desktops.

Windows reliability for laptops and desktops, by manufacturer

This trend holds true across the three manufacturers with the most Windows devices being monitored by Aternity.  For each of the three vendors, desktops outscore laptops in Windows reliability.

Windows reliability scores are higher for desktops than laptops, for all three of the top vendors being monitored.

Comparing reliability across ALL monitored device types

The results are even more dramatic when you add virtual desktops, which beat out desktops. They’re significantly more reliable. A likely explanation for this is that the IT department invests in the stability of the servers and OS images that host and create virtual desktops, since so many users depend on them.

Laptops have the lowest scores for Windows reliability of the four device types.

Surprisingly, our data shows that tablets are more reliable than laptops. Bear in mind that this includes the data for my own laptop, which suffered an unfortunate accident involving a bicycle and a squirrel. The squirrel survived.

Comparing Windows reliability of two virtual desktop vendors

When it comes to virtual desktops, reliability scores hardly varied with the manufacturer. The two vendors with the largest population of virtual desktops being monitored by Aternity had virtually the same reliability. Over this monitoring period, Aternity reported scores of 8.09 and 8.15 for VMware and Microsoft respectively.

The two vendors with the most monitored virtual desktops had nearly the same Windows reliability scores.

Enterprise Windows reliability, by industry

As discussed above, many factors affect Windows reliability scores. Nonetheless, here’s a chance to compare your own Windows reliability experience with that of other companies in your industry.

Reliability scores vary by about 20% across industries.

Comparing Windows Reliability by operating system image for two companies

Since enterprises install Windows from an image that’s prepared in-house, it’s interesting to compare the reliability of similar devices used in different companies. We looked at the reliability scores of several thousand Dell desktops deployed by two different companies. The result is a 39% variance between the two companies.

Windows reliability scores for the same device and OS can vary widely across companies, based on the maturity of Desktop Services practices.

This result is not that surprising. A company that carefully builds and maintains its images is likely to have higher reliability.
