Windows 10 Insider Preview October Update KB3103470

The summary of this update says: “This update includes improvements to enhance the functionality of Windows 10.”

Which is about as basic as an explanation you can get. In fact, according to Microsoft’s support page, it appears to be focused mainly on improvements to Notepad – which is funny on its own.

If you’re a Windows Insider and testing out the new builds of the next big upgrade codenamed Threshold 2, you can get this October update by heading to Settings > Update & Security > Windows Update.

Windows 10 Preview October update

Microsoft has rolled out a lot of different notable updates and builds this week including a new version of Windows 10 Mobile Build 10549.

I installed this on my test Lenovo Flex 2, and it didn’t even require a restart and everything seems to be working just fine.

But let us know how your update experience goes for the good or bad in the comments below.

    DO NOT INSTALL THE LATEST DEFENDER UPDATE. I did and it locked my Surface 3 in a cycle of blue screens and attempts to reset that failed.
    I finally, after 1 hour of going thru different menues to come up will a reset to basic win 10 that’s working. I’m now updating all of my apps and programs, and I doubt I will join the INSIDER PROGRAM AGAIN.
    seriously thinking of returning the Surface 3 still have a few days left on my 30 day return.
    Update. My nephew just informed me that his Lenovo Yoga did the same thing.
    I gues Microsoft is not ready for prime time. Win 10 should not have been released u til it was ready.
    I’ve been working on this restore for 10 hours. Really tired, and tired of these problems.

    I don’t see any reference to Notepad on the linked support page (and I was so looking forward to the improvements :-)
