Windows users face massive update bloat, tough choices

Windows 10’s cumulative updates have ballooned in size, and a similar bloat will also affect the Windows 7 updates that Microsoft revamped this month.

According to data published last month by LANDesk and refreshed by Computerworld with October’s numbers, Windows 10 cumulative updates for the three versions of the new OS have surged in size.


Updates for Windows 10 version 1507—the debut that launched in July 2015—have grown 153% (for the 32-bit edition) and 181% (64-bit), from 184MB and 368MB to 466MB and 1,034MB (or over a gigabyte), respectively, in just over a year.

Those for version 1511—Windows 10’s first “feature update,” issued in November 2015—exploded in comparison: The first 64-bit 1511 update was 49MB, but the cumulative update released earlier this month was a whopping 989MB, for a growth rate of 1,918% in under 12 months.

The newest Windows 10, version 1607—released in early August—has also expanded, with the 64-bit edition climbing 591% from 113MB in August to 781MB this month.

“Cumulative updates start out big and become enormous over time,” Stephen Brown, director of product management at LANDesk, a maker of enterprise endpoint management software, wrote in a post to a company blog on Sept. 21.

Updates increase in size because they are cumulative; October’s 989MB update for 1511 included not only new fixes, but also those in every prior update. September’s, in turn, included new fixes as well as those in August’s and July’s and June’s and....

And so on and so on.

August announcement of the change to Windows 7’s update scheme.

The “convenience roll-up” Mercer mentioned was about 477MB in size (for the 64-bit version). Microsoft issued the roll-up in May.

In another answer, Mercer got more specific. “Eventually [the Windows 7] Monthly Roll-up will grow to around the 500MB size,” he said.

If Windows 7’s updates were to grow at the pace of 10’s, the former would top the roll-up within a few months: Using the expansion of Windows 10 1511’s updates as a guide would mean Windows 7’s cumulative update for April 2017 would be approximately 1.6GB, or more than triple Mercer’s bet.

That’s not likely, said McMillan, for the simple reason that Microsoft is not fiddling with Windows 7 features at this point, but instead patching vulnerabilities and fixing bugs. McMillan predicted that the Windows 7 cumulative updates would reach Mercer’s 500MB estimate, probably within a few months, but then grow from there only slowly.

But even updates of that size will choke some customers.

A few users and IT administrators expressed concern about the expanding updates as soon as Microsoft announced the new servicing regime. “This may impact bandwidth to download and install,” wrote someone identified as Kiran in a comment appended to Mercer’s August blog post.

McMillan has been fielding similar inquiries from LANDesk customers. “I’m getting multiple calls each week about bandwidth,” he acknowledged, referring to the Windows 7 cumulative updates. “A lot of them just don’t have a fat pipe, so this is an entirely new problem for them.”

McMillan cited retailers and healthcare organizations as examples of users with limited Internet bandwidth—some with nothing more than dial-up connections, others who rely on satellite-based Internet—who will face time-consuming downloads as the cumulative updates grow in size.

Previously, updates could be individually selected—each security patch or hot-fix approved or rejected by IT administrators—to fit the specific needs of each system, resulting in small-sized downloads. But with the all-or-nothing nature of the new Windows 7 cumulative updates, those users were suddenly locked into taking everything Microsoft offered, or leaving machines vulnerable to attack.

Windows users would have had to deal with the cumulative concept at some point—when they migrated to Windows 10—but the change to the Windows 7 servicing rules put it front and center months or years earlier than many figured.

“This will have a huge impact,” McMillan said. “[Users] are having to make choices they haven’t had to make before.”
