Step 1: I suggest you to run SFC scan,
System File Checkeris a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• Right click on the Start button, click on
  Command Prompt (Admin).
• Type “sfc /scannow” without the quotes and hit
  Enter.
• After the scan, restart the computer and check for the issue.

Step 2: Also, I suggest you to update the display drivers and check.

Steps to Update the Display Adapter driver.

• Press Windows key + Xkey when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Update driver software

BUT i still have the line on screen.

 

printer margins in inches not cm

just recently installed Windows 10 v2004 preview. but both Chrome and Firefox browsers are showing printer margin settings in inches not cm. Print preview in chrome shows margins in inches yet the page is set to A4. I've check me Dell 3330dn laser printer settings and default page size is A4. I've had this problem before and I think it got corrected by changing the page size from letter to A4. but its set at that already.

my Windows 10 was installed from Windows10_InsiderPreview_Client_x64_en-gb_19041.iso so thats british english ISO not american english. I let Windows detect and install the printer driver for my Dell. I do have the install .exe but I just need the driver and nothing else.

Firefox installed 75.0 win64 EME-free en-GB, again print preview shows margins in inches not cm.

page setup in Notepad shows paper size A4 and margins in millimetres.
