The Windows 10 Anniversary Update was well received by the audience and it should work just fine for you as well. However, there are still some glitches to be solved. Sometimes you will find that an update install can cause your programs to disappear altogether. Of course, there are a lot of ways to recover these items, and you can check out some of them here. Other times, you might need to tweak your Windows a bit after a major update. But what if you just discovered that a whole computer partition has gone missing?
The Windows 1o anniversary update mystery
Some users that have done the Windows 10 Anniversary update have complained that they’ve apparently lost whole disk partitions. Others say the their disk partitions are shown as not being allocated.
There is no quick fix for this but, you might want to go back to the previous version of Windows 10 that you had been working on until the update. This can be done within 10 days after installing the Windows 10 Anniversary update and will solve your issue. You will find out that the information you had on the seemingly lost disk space is not lost. It’s just a glitch of the anniversary update. To do this just click “settings”, then go to “update and settings”. Select “recovery” once there and then “get back to an earlier build.”
Well you’ll be disappointed to find out that there is no permanent solution yet. The folks down at Microsoft say that they are “actively working on that” for now. Some users have seen their problem fixed by applying KB318966. It seems this helped solve the issue.
What is KB318966?
KB318966 is what you call a Cumulative Update for Windows 10 (version 1607) that can be installed on top of the Windows 1o anniversary update. If you install the update, then your partitions will become visible again. The software will recognize them appropriately. Still, even with the cumulative update in place, you might still face the same problem.
Hold your horses!
If none of the two presented solutions have done the job, don’t rush. Don’t go all Kung fu on your computer and try to format the seemingly free space because you’ll lose your data. It’s not a good idea to recover the files using other software either. Just stay calm and let the programmers do their thing. They’ll come up with a solution in no time.
