For Online Computer Support, Ask a Computer Technician
Hi. My name is***** you for your question and the opportunity to assist.
Can you tell me what type of repair or service Dell did on the computer?
Please reply in the box just below.
Click the start menu button and open Settings (the gear icon)
click Update & Security
On the left select Windows Update then click Check for Updates.
I really don't know what Dell sent back to you but this will get Windows
up to date and likely fix many of your issues.
