However, many of them are wondering “Will upgrading to Windows 10 delete my files” or “Does upgrading Windows delete files”?

According to Microsoft posts, your data will be safe throughout the upgrade. However, Windows 10 users’ feedback shows that some users encountered data loss issues after upgrading to Windows 10. Here you can see a true example:

I've just upgraded one of my machines to the free Windows 10 upgrade. After the upgrade, my software shortcuts are still on the desktop, but all of the files I had there are gone. I can't find them anywhere. Not even in the "Windows.old" folders. This is after the upgrade claimed that it would keep all files and software on the machine.


As you can see, it is an annoying issue when you lost your files after upgrading to Windows 10. In addition to data loss, partitions might disappear after the Windows update.
