With only a month to go before releasing the Windows 10 October 2018 update, or version 1809, Microsoft's latest preview build is all about eliminating glitches rather than introducing new features.
Both contain over a dozen bug fixes each, with the earlier of the two addressing GSOD or 'green screen of death' issues, crashing apps, false 'You're up to date' messages, and flaky network connectivity.
The latest preview fixes a host of minor bugs, several issues causing crashes, and weird glitches that would annoy the masses if they slipped through to the final release.
And Microsoft expects to iron out more bugs in coming weeks as it enters "the phase of checking in final code to prepare for the final release".

Some insiders may have previously noticed that quickly opening one taskbar flyout after another, such as network or volume, would jam the popup.
And insiders with multiple monitors may have noticed that if the Open or Save Dialog was moved between monitors, they'd unexpectedly shrink. Microsoft has fixed this.
Crash events fixed in this preview include one caused by a pen writing on Edge web notes, as well as Task Manager crashes, Settings crashes for multi-monitor setups, and a crash that happened when clicking the Verify link on the Accounts Setting page.
Microsoft also fixed two glitches affecting PWAs or Progressive Web Apps, which started to appear in the Microsoft Store earlier this year alongside the Windows 10 April 2018 update, the first version of Windows 10 to support PWAs.
Twitter, Pinterest, Tinder and a host of other sites have launched PWAs, which work offline, and visually appear to work outside the browser.
According to Microsoft, previously clicking on links in PWAs like Twitter didn't open the browser. Also some PWAs were not rendering well after the app was suspended and resumed.
This build also fixes a bug that caused League of Legends and the games to fail to launch or connect properly.
The October 2018 Update will mark the sixth major Windows 10 release, which are now rolled out twice per year, since Microsoft moved Windows to a service model in 2015.
