The user said the same thing happened to them on an earlier Build 25131. However, there is now video and photo proof, unlike last time.
The rounded taskbar appears randomly and persists even after a display driver update, but after the user restarts explorer.exe via the command prompt, it disappears.
Of course, there is some speculation that this could be fake evidence. Neowin founder Steven Parker recounted his views in a Reddit thread, saying that perhaps the change was made through a third-party app like RoundedTB, which was then uninstalled. Therefore, when explorer.exe is restarted, any changes made by the application will be reverted. However, the original whistleblower denied this and stressed that they had no reason to deceive people.
It’s not unusual for experimental features to appear unexpectedly for specific users. Earlier this year, ad banners started appearing in some people’s file browsers.MicrosoftIt was later explained that this was just a testing process, not for an external release, which may be the case now.
