American citizen living in germany here. I purchased Windows 10 from a local electronics store for my new DIY pc build. The software was of course in german. I originally thought it would give me the option at the start of Windows installation to choose English. No such luck. I instead completed the installation in german and downloaded the English language pack from the control panel. I made it my primary language and removed the Deutsche language pack. Then I went into the Windows folder and deleted the deutsche folder from there. The problem is, my Windows is now about 95% English. I have this annoying small number of ui Windows that will pop up and be in german. Another example is before the login, the date will feature a german day of the week and the word "password" is the german word for password. How do I get this thing to 100% English?
