After consumers reported a number of problems with the latest major update to Windows 10, Microsoft responded by preventing the October 2018 Update from being installed on some systems. Microsoft announced that the Windows 10 October 2018 Update was available for download when it announced its new Surface Pro 6, Surface Laptop 2, and Surface Studio 2 at a media event on October 2 in New York City. Since then, users have reported a number of wide-ranging issues caused by the update, including lost files, issues with CPU usage, and reduced battery life post-update.
The problem with disappearing files has been widely reported on various social media forums, including on Reddit and Twitter, with one user reporting on Microsoft’s community forum that he had lost up to 220GB of data after the update. Affected file types include documents, music, and photos. “I have just updated my windows using the October update (10, version 1809) it deleted all my files of 23 years in amount of 220gb,” forum member Robert wrote. “This is unbelievable, I have been using Microsoft products since 1995 and nothing like that ever happened to me.”
This problem may be caused by OneDrive. Twitter user @coolkevinator noted that if you have locally stored items that aren’t also saved to OneDrive, the Windows 10 update will wipe out the files stored on your computer. “Heads up to anyone updating windows,” the tweet said. “Apparently, if you have documents saved in your user directory, i.e. users/JohnDoe, and not one drive, the update will delete EVERYTHING in that location. So if your ‘Documents’ or ‘Pictures’ don’t have a one drive symbol, MIGRATE IMMEDIATELY!”
According to MSPowerUser, rolling back the install the previous version of Windows 10 does not bring back the files. If you’re updating to the October 2018 Update, be sure to backup your file to an external drive, OneDrive, or another cloud storage service in case of data loss.
Another issue caused by the update relates to the Intel Display Audio driver. This glitch affects users running PCs with Intel’s 6th-Generation Skylake processors or newer. Users reported excessive CPU usage, which will lead to diminished battery life. Microsoft and Intel both acknowledged the issue, and Microsoft has halted the update to affected systems. “To ensure a seamless experience, we are blocking devices from being offered Windows 10 version 1809, until updated Intel device drivers are installed on your current operating system,” Microsoft said on its support page. “We recommend that you do not attempt to manually update to Windows 10, version 1809, using the Update Now button or the Media Creation Tool from the Microsoft Software Download Center until newer Intel device drivers are available with the update.”If your system is affected, you can manually download the Intel Graphics Driver prior to downloading the Windows 10 update. This driver also contains the fix for the Intel Display Audio driver glitch.
Although the October 2018 Update is available now, it’s not an automatic process yet. You can manually check for the update by going to Settings, Windows Update, and then Check for Updates. The update should automatically download for all users starting October 9.
For now, users should hold off on updating their Windows 10 PC until Microsoft addresses all the early complaints from the download. If you must download the October 2018 Update, we highly recommend that you back up all your files and install the Intel Graphics Driver before proceeding.
I wonder if the file deletion is related to the fact that Microsoft wants to force you to store files on OneDrive that you pointed out, but garbage coding flagging files for deletion before moving them? Either way it's another good reason to sync files to a personal NAS, an external drive, or at least an second internal drive, at least weekly. I prefer an NAS and a program called "SyncBack" https://www.2brightsparks.com , have used it for years, as they made their free edition much more powerful starting with version 8, there are no ads or nag screens, and, most importantly, you can set profiles to run on a schedule (which uses the standard Windows Task Manager).
