Cannot use "CMD" in 8.1 using Microsoft account

I've got an issue with a Dell Latitude 10 tablet running 8.1. I bought the tablet used and everything else runs as it should except for this one weird issue.. It was running 8 originally. Since I use a Microsoft account on all my other devices I set that account on the tablet making sure I had administrative rights. I was unable to get to a command prompt either normally or running as administrator. I've tried from run and task manager too. I then made a local account and was able to access cmd just fine from there. After doing all the normal troubleshooting (sfc,updating bios and drivers, etc,etc) I turned bit locker off and did a clean install with all updates of 8.1 but the issue still remains. I read somewhere to check the registry HKCU\Console\Full Screen with a value of 1 (it already existed).
I can't upgrade 8.1 to Windows 10 on this device as Intel or Dell doesn't have a display driver for it so I'm stuck with 8.1. For the life of me I can't understand what difference it makes between a Microsoft account and a local account. I don't know where to jump next. Before I revert back to a local account does anyone have any ideas?

What happens when you try to run cmd.exe from a Run box or Start menu? What error do you get?
Have you looked in Event Viewer to see if anything is being logged when you try to run cmd.exe?

What happens if you use Windows Explorer to browse to C:\Windows\System32 and run cmd.exe or right click on cmd.exe and select Run as administrator?

Absolutely nothing

No matter where I try to access cmd, whether normally or as administrator, I get UAC and then nothing-no error no window of any kind. (except from run which I get nothing, not even UAC) Nothing is being logged in event viewer that I can tell. I even tried adding another Microsoft account which doesn't work either. Local account works fine in all aspects. I also tried completely disabling UAC. The only anti-virus is Windows Defender and turning it off didn't help. It's no huge deal but it is surely unhandy to have to logoff and back in to use cmd. Also, my storage on the tablet is small so having multiple user accounts is not ideal. I have 4 other devices using my Microsoft Account and have no problem. I thought the clean install would surely fix it but didn't. It beats the hell out of me!!

Try running the following commands from a Elevated Command Prompt.

Dism /Online /Cleanup-Image /StartComponentCleanup
Dism /Online /Cleanup-Image /RestoreHealth
SFC /scannow

Takes awhile but fixes a lot of strange problems like the one you are having.

Did I miss something? He cant run CMD so you want him to run commands in CMD?
Can you run Powershell? Try there.

No you didn't miss anything, I did. Don't know where my mind went on that one.

Powershell is an excellent idea though.

I'm "powershell" challenged

Many thanks to you for taking your time to help me. I was able to get into powershell using my Microsoft account. I just didn't know what to do once I got into it. I can only do the most basic stuff using CMD and powershell is a completely gray area for me. I wasn't sure if the syntax for powershell commands were the same as CMD. I downloaded the current "help" files and quickly discovered the syntax in the help file was way above my head. After fumbling around a while I managed to run Dism which according to the log did not repair anything. I also managed to run SFC which found nothing. Like I said it's not earth shattering that I can't use CMD using my Microsoft account. I'm just one of those people that asks "WHY???" I sure wish I could run Windows 10 on this little tablet but many of us first generation 8 tablet users can't. Damn Intel for not supporting the Atom processor and damn Dell for using them. Thanks again

Just found this: Elevated Command Prompt won't start on Windows 8.1

See if running Command Prompt from C:\Users\Account Name\AppData\Local\Microsoft\Windows\WinX\Group3 works or not. Also try the one in SYSWOW64

I tried the solution in that thread with no results. I don't have syswow64 as this is 32 bit Win8.1 with 32 bit uefi. I'll just have to put a little effort into learning powershell. Thanks again for all your suggestions. If you happen to get a brainstorm regarding this in the future let me know.

Strange but I just had the same problem after updating to the latest Windows 10 Threshold2 release, could not open a Command Prompt. Fiddled around for awhile the4n restarted and it works again. It's happened twice so far. I depend on Command Prompt so if it doesn't work and I can't fix it then I will tray a refresh and if that doesn't help a clean install.

I've been fiddling with this 8.1 tablet for days and haven' turned on my Win10 machine so haven't gotten threshold 2 yet. Just interested, did you make a local account to see if cmd would work using it? I'll update my 10 machine today but if what you say is true I'm going to do a backup first.

I only use a local account on this computer.

If it happens again I will try creating a new account, see what happens.

The error I was getting was 0xC0000018.
