If they correct many safety flaws, the latest versions of Windows 10 and 11 deployed with the August Tuesday patch also cause strange problems among some users.
On August 12, Microsoft broadcast its monthly security updates, both for Windows 11 and for Windows 10. As always, they had to correct a large batch of faults-107 in total, including Zero-Day vulnerability-and improve the general stability of systems. However, these routine updates quickly sparked a series of problems, to the point that Microsoft had to publish rustines of emergency a few days later.
If the KB5066188 for Windows 10 was logically satisfied with a few fixes, the KB5063878 version for Windows 11 24H2 has inaugurated several new features, already introduced into the optional update offered a few days earlier. Let us thus quote new tools such as automatic rapid recovery, which tries to repair a defective start by downloading a targeted fix, or a black screen of death with remained design. The alignment of windows with the SNAP function was made more educational with new reminders. And the PC Copilot+ have won unpublished functions, including the famous Recall, now available in Europe, or Click To Do, which allows you to perform smart actions on a selected text or image.
Patch Tuesday of August 2025: an impossible reset
However, as often with Microsoft’s updates, everything did not go as expected, and the new Windows versions have introduced their share of new problems.
One of the first reported setbacks concerned the reset of the system. On Windows 10 as on Windows 11 version 23:2, the “Reset this PC” suddenly refused to operate after the installation of August updates. The process was suddenly stopped, canceling the changes. Although personal data was not erased, the function became unusable, compromising the ability of many users to restore their computer in the event of a serious problem.
Microsoft quickly confirmed the existence of this embarrassing bug and published, on August 19, two out -of -band fixes: KB5066188 for Windows 10 and KB5066189 for Windows 11 23:2. These updates restore the possibility of resetting the system, without adding additional security fixes. They do not automatically settle: only users confronted with the bug or need to reset their machine are invited to apply them, in order to find a normal operation.
August 2025 patch: a concern with the SSD
While reset was recovered, another problem appeared, this time limited to Windows 11 24H2 and more worrying for data. Several users, mainly in Japan, reported that their SSD became illegible or completely disappeared after massive scriptures on an already full disc. The exact conditions of the bug seem very specific: the phenomenon appears when the reader is occupied more than 60 % and he undergoes a writing charge of 50 GB or more. In this case, the SSD sometimes ceases to be detected, the explorer plants, and the partition can be found in RAW format, making the files inaccessible.
The first reports mainly point to SSDs equipped with pHison controllers, even if other brands like Innogrit or Maxio have also been mentioned. No cases has yet concerned the discs of major brands like Samsung or Seagate. Microsoft confirmed to investigate in partnership with the manufacturers concerned, without proposing any corrective or immediate bypass. However, the publisher insists on the scarcity of documented cases, which represent only a minimal fraction of Windows 11 installations.
The fact remains that the consequences of this bug can be severe for the users concerned, ranging from data loss to the full replacement of the storage medium. Several experts in order to regularly recommend saving its important files regularly and, if possible, to postpone voluminous data transfers on an already full disk, while Microsoft publishes a fix or provides details.
Windows updates: an always delicate exercise
These successive incidents prove once again that Windows updates are delicate. Already, we can be surprised – even indignant – of the large number of faults corrected each month with the Tuesday patches: a hundred on average, or several for Windows 11 since its release … Admittedly, all operating systems have vulnerabilities, including Apple. But the fact that Microsoft in TEMMATE of dozens each month for Windows 11, supposed to be its surest system, is not reassuring, especially when you think that there are constantly new fixes – wait September! – and therefore new flaws to fill. It is really a specificity of the software world to put in circulation as many poorly finished products, which must be continuously repaired.
These various concerns, alas recurrent, also show that Windows 11 is not the marvel promised, the system always lacking in finishes, as we have pointed out several times. Full of heterogeneous modules and components, and often very old, it still drags a heavy heritage which poses coherence problems. Thus, Microsoft is just beginning to prepare the passage in dark mode of windows from another time, without giving a precise date of standardization.
However, let’s not be too severe. Because if these problems are undeniable, as Microsoft has recognized, it should be noted that has a lot to face the multiplicity of the material configurations to be managed, unlike Apple, which controls all its products by locking them. Above all, we have never encountered any really blocking problems on our various PCs under Windows 11, no same blue screen of death – the famous very frequent BSOD on the old versions. And, in our case, we have not noted any concern by installing the KB5063878 on several computers. Without ignoring them, it is therefore advisable to put the problems encountered by certain users who undoubtedly represent only a low percentage on the hundreds of millions of PCs in activity.
Anyway, to avoid problems arising from Windows updates, our advice always remains the same: wait a few days before installing a TUEDAY patch, time to see if users and experts signal concerns!
