File System error (-1073741819) on Windows 10

I am receiving File System error (-1073741819) while opening .exe files and while opening apps in Run as Administrator mode. I am not also able to run Command Prompt in admin mode. I noticed the error only recently, though I am not sure if I can blame it on Windows Update or UAC changes I had made. I am not able to set the UAC back to default. Is there a fix?

Hi Mukhthar,

I understand you are unable to change the UAC settings and you get a file system error.

This might be caused due to the following reasons:

  1. UAC settings reg values changed.
  2. Windows system file corrupt.

Please follow the below method and check if it helps:

Method 1: Rebuild UAC using registry.

Follow the below steps:

To resolve this issue, change the registry setting. To do this, follow these steps:

Thank You for your help. But I couldn't solve the problem.

I am not able to run registry file (since that requires admin privilege) or open command prompt with admin privilege. It seems I cannot perform anything that requires admin privilege. The UAC notification box that appear on performing admin action flashes and then the error box appears.

Hi Mukhthar,

Thank you for the reply.

Sorry to hear about the inconvenience caused.

This problem seems to be user account specific, creating a new user account will help, but the problem is you can not create a new user account from this account.

In this case I suggest you perform a refresh on the computer.

Please refer to the below suggestions to refresh the computer:

  • Click Windows flag key.
  • Select settings.
  • Choose update and Recovery.
  • Now select Refresh.

Please note Refresh will remove all the applications that you have installed and your data will not be touched.

Hope this information helps, for more assistance please reply.

I have the exact same issue after upgrading to windows 10 from windows 7.  I cannot install files, run cmd as admin, or do anything.  Stating that we all need to do a refresh goes against the whole grain of a seamless upgrade to windows 10.  I have hundreds of applications and will not just have all of them removed at a whim because of something Microsoft did to UAC.

Please provide a real solution.

  1. Create a new user.
  2. Make sure user is an administrator.
  3. Login as the new user.
  4. New user has admin rights.
  5. Run the reg file and update UAC.
  6. Run sfc /scannow and it finds "zero" errors.
  7. Reboot machine.

New account has admin rights.

Old account has "no admin" rights.

Still not fixed.

Please provide a solution for old user accounts.  Performing a refresh is not a solution.

Hi,

I am also experiencing this issue after upgrading from Win7 Ultimate.

Resting windows or creating a new profile isn't an option.

Please give us a proper solution to fix the old profiles.

Hi,

I've found solution - make new account with admin rights, log into it, change option UAC in interface to minimum, log into old account and everything should be ok, later u can change settings to prompt when using admin rights. 

greetings!

This is absolute tosh. You can't just create a new account, you need a Microsoft account to do so. if you don't have one you need to make one, and obviously you cant use the same one. this is not helpful in any way. Again microshaft you have released an incomplete OS full of bugs and expect us to do all of your debugging for you. You should pay us to test your systems. Now I understand why its free, you get what you pay for.
