I have used Windows 10 since it was introduced. Only this week has it begun to mis-label files with the wrong date. Not just a little but a lot. Three files, in different programs (Acrobat, Quickbooks) were created in the past three days and all dated November __, 2007. When I modify them that date is retained. I have installed NO new software or used any freeware in the past month. I read this problem has happened in the past dating back to 2018 in the blogsphere.
