Windows 10: How do I uninstall McAfee software using only Command Prompt?

    How do I uninstall McAfee software using only Command Prompt?


    Hello everyone, I'm new to these forums.

    I am currently having issues rebooting my PC after trying to install the McAfee Internet Security on my computer. The PC will not reboot and I still have files on my desktop which I need to recover before resetting my PC. This will be my 2nd time resetting the PC to factory default and I am trying to avoid going through the hassle of reinstalling all my programs again.

    I figure if I could delete the McAfee program from my desktop, it should be able to help my PC reboot. However I only have access to the command prompt and I tried the method outlined in the Windows 7 forum post here: Programs - Uninstall using Command Prompt in Windows - Windows 7 Help Forums.

    However it didnt work as I had the same error message as forum poster kasihra. This is the error message:
    Node - MININT-BIRNS7C
    ERROR=
    Description = Invalid class

    Is anyone able to help point me to the right direction to solve this and get my PC running again? Thanks all in advance !

    You said you cannot reboot.
    If you go back and restart the computer, do you have the sign in screen ?
    If yes, do NOT sign in.
    At bottom right, there is a Power icon > click it will give you the Restart option. Yes ?
    Press the Shift key and hold it > now click the Restart option > click Troubleshoot > click Advanced options > click System Restore .
    Choose a date before you installed McAfee as your restore point.
    If you can follow the steps this far, you should be doing the system restore.
    Please post back the result.

    Hi Davidhk,

    Unfortunately I havent gotten to a point to set up the system restore on the PC....There was no image for the PC to restore it to, that is something I have to remember to do the next time. Are there any alternatives I can do to remove the McAfee program? I only have the command prompt to play around with at this point in time

    You can't login to computer, you can't uninstall McAfee.
    Sorry.

    I understand using a Linux "live dvd" will help you retrieve and backup your personal files from Win 10, but I am not well versed enough to tell you how to.
    I know how to install and create a Linux Live DVD etc. But since I barely know about Linux, I don't want to give you a "half-baked" instruction.
    Please wait a bit for someone to come along.
    Thank you and good luck.

    excerpt :
    Recover files from a failing drive

    We’ve all been there. Your PC may not boot, Windows may be showing errors and blue-screening, or—even worse—you may hear that dreaded mechanical hard drive clicking.
    Even if you can’t boot Windows, there’s a good chance you can read the drive from within Linux and recover some files before the hard drive dies completely. Or, if the Windows system is corrupted and the drive itself is fine, you can recover all of the files from outside Windows.

    Don't know why the user would need to try Linux ?? When we have a better option made by one of our own right here.
    Windows 10 Recovery Tools - Bootable Rescue Disk
    Just put this on your USB stick, and boot it up. Has MANY programs that may help you, also incudes a image backup program.
    Plus access to all your drives on your computer, which you could remove/delete that app, manually of course. Worth a look.
