Hi, I had a problem that I didnt have SQL SERVER NETWORK CONFIGURATION in SQL SERVER CONFIGURATION MANAGER.
I tried to remove all the sql in my computer and install it again from the begining, but mor damge created.
Now SQL SERVER CONFIGURATION MANAGER has a MMC problem. and not the SQLEXPRESS service didnt removed.
I need to remove all the instances of SQLEXPRESS/01/02/03 that created from the installations I've tried and reinstall it all again.
Even uninstall from control panel or from remove/uninstall of windows didn't help.
Please help me.

Please try to open the Registry Editor, search the Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\MMC\SnapIns{84a016c0-5617-4a05-ae8c-c806c5ff3e20}, then check the value NameStringIndirect and the Data, next find whether SQLManager.dll exists according to the path displayed by the Data.
If not, please try to pick SQLManager.dll from another machine having the same version of SQL Server, or repair Shared components of SQL Server.
More details please refer to this article.
