Public Network won't change to Private

If you have Windows 10 Version 1709, click on the wireless icon, Properties, and you can change the setting.

For lesser versions or Windows 8, it is easier to delete the wireless profile, restart and remake the profile.

Open cmd.exe with Run as Administrator and  then:

netsh wlan delete profile name="profile name"

I have no ability to change these settings in Win10 Pro.

You need to get your IT Administrator to do it or give you access to do it.

We are a small remote office with no IT admin. We setup a new wireless access point and now my Win10 Pro laptops are connecting as Public. I will try what you have suggested.

See if you can set up an Admin account on the laptop. Be careful using the registry if you are a small company. Changing from Public to Private does not require registry changes.

my account is an admin in Windows. I still have no option - it is not that it is greyed out it simply doesn't exist.

So then something wrong with the operating system.

First try DISM

Open cmd.exe with Run as Administrator. Run dism.exe /oneline /cleanup-image /restorehealth

Restart and test.

If that does work try a Windows 10 repair install.

Windows 10 is running, so click on the Download button (not Upgrade Button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.

Enabling Discover my PC resolved it. Thank you!
