The issue is that the instance of visual studio has a nickname associated with it. Use the following instructions to change the nickname of an existing Visual Studio (tested with VS2017) installation (partially lifted from https://developercommunity.visualstudio.com/content/problem/99059/not-able-to-easiliy-change-installation-nickname.html):
Set the nickname in the *.isolation.ini files in
%ProgramFiles(x86)%\Microsoft Visual
Studio\2017\[Version]\Common7\IDE.Set the nickname in the state.json file in
%ProgramData%\Microsoft\VisualStudio\Packages\_Instances\[InstanceId]\state.jsonOpen regedit, go to under path
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall, find there “Visual Studio {your version} 2017 (2)” (The folder will have a different name use the regedit search with “(2)” to find the corresponding entry. Rename string to be without ” (2)” – this will change application name appearance in control panel / program and features.
You’ll need admin permission to modify these files. If you want to remove the nickname altogether, just set it to an empty string (e.g. Nickname= in the .ini files, "nickname": "" in the .json).
Note that this will only have affect within VS tools, such as the VS installer in the screenshot you posted. Any names with the suffix in, for example, the Start/Windows menu will need to be renamed manually.
