Windows 10: environment variables

I have accidentally deleted all environment variables and now can't reset PC, sound problems and having errors withsoftware installations and running of other apps

System environment variable won't stick

Running Win10 Home on an Acer Spin 3, 64bit, i7cpu. I try to add a path to the system environment variables by:

1. Control Panel > System > Advanced system settings > Advanced tab > Environment variables

2. The "Environment Variables" window opens.
3. In the "System Variables" pane I select "Path" and click the EDIT button.
4. A list of the current system paths is displayed.
5. I click the NEW button, browse to the path I want to add which is "C:\Python36-32" and click OK. The path "C:\Python36-32" is added to the list of current system paths.
6. I click OK and am returned to the "Environment Variables" window.
7. I click the "X" at the top right to close the "Environment Variables" window.

Now if I click the "Environment Variables" button again (end of step-1) and repeat steps 2-4, the new path I added in step-5 is gone. IOW, adding a new path won't stick.

What am I doing wrong?

 

Searching environment variable in list

I'm using a command that gives me a list of environment variables. When searching in the list, I want to find all environment variables with the word
EXTERNAL; using the following command all that is occurring is all the environment variables are being listed instead of those environment variables with the word
EXTERNAL ?

findstr /c "EXTERNAL"

 

Environment Variables

I do apologize or this inconvenience.

You cannot modify user environment variables in the system properties if your using a standard user account in windows.

To do this, follow these steps:

> Click StartStart button

> Type Accounts in the Start search box

> Then click User Accounts under Programs.

> User Account Control permission If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

> In the User Accounts dialog box

> Click Change my environment variables under Tasks.

> Make the changes that you want to the user environment variables for your user account, and then click OK

Hope it will help.

Please let me know if you need any further assistance.

Thank you and Keep Safe.
