The classic Notepad app now supports EOL in text files that were created in other OSes. However, many users don’t need it or have the problems that may be caused by it. If you don’t need EOF in these files, you can easily disable this feature.
In the latest update for Windows 10, there are changes for the native Notepad app too. Now it supports the End of Line in txt files that were saved in Unix, Linux, and Mac. However, it may cause issues with displaying the content in classical Notepad.
You can revert this changes and use your Notepad as earlier. Before doing any of this, you should create a backup of all the information you are going to change.
Press Win+R to open the Run dialog. Type regedit and click OK, the Registry editor will open. In the left panel, select HKEY_CURRENT_USER\Software\Microsoft\Notepad.
In the right panel, find the fPasteOriginalEOL line and double-click on it. If its value is 0, change it to 1 and save. You should also do this with the fWindowsOnlyEOL parameter.
After doing this, just run your Notepad and open any file in it. The app should work as it worked before the update. If you will need to use the EOL in files again, just do the same but change values from 1 to 0.
