What is the Cumulative Update for Windows 10

Windows 10: One cumulative update chases the next

For the third time since the release of the new operating system, Microsoft released a cumulative update for Windows 10 called KB3081438 on August 14th. As with the previous updates with the numbers KB3081424 and KB3081436, these are updates that correct malfunctions and instabilities that have occurred since the release and in some cases also close security gaps.

The high update frequency allows the conclusion that the manufacturer is currently still finding a lot of errors in Windows 10 that should not be corrected on the following patch day, but as soon as possible.

Diffuse explanations

As with the previous cumulative updates, Microsoft does not care about a detailed description of all resolved problems with the current update. Rather, Microsoft mainly lists the files replaced by the update. After all, the manufacturer names the security gaps that have been fixed in the respective update.

In general, cumulative updates have the advantage that a large number of errors can be fixed in one go. If Windows 10 is reinstalled or if it has not been in operation for a long time, a cumulative patch can reduce the number of updates to be installed - only the latest package has to be downloaded.

Not just an advantage

However, the procedure also has disadvantages: Especially after the release of KB3081424, we received messages that the installation of the update kept going wrong - which led to an endless loop of failed installation attempts due to the update requirement in Windows 10.

If you block a cumulative update, for example in a WSUS environment, a whole series of security and / or other problems remain untreated. According to some reports, a clean reinstallation of Windows 10 fixed the problem. How many users are affected by the problem is currently difficult to assess, especially not how high the proportion of the total installations of Windows 10 is.

Catching up

So far, Microsoft has only made few statements about the installation rate for Windows 10. The upgrade is said to have been installed on 14 million devices worldwide on the first day of its availability, as far as Microsoft has at least announced the first figures.

According to the analysis company StatCounter, Windows 10 now runs on around every tenth computer in Germany. StatCounter calculated a market share of 9.93 percent for the software as of August 15th. The previous version, Windows 8.1, runs on 17.75 percent of computers. But Windows 7 is still the most widespread, with a share of 51.38 percent. Apple's Mac system OS X comes to 8.84 percent.

According to StatCounter, the spread of Windows 10 in Germany is above the global average of 6.19 percent. Windows 8 and Windows 8.1 would come together to 18.63 percent. Microsoft's older Windows 7 system also dominates worldwide with a share of 53.61 percent.
