You will then be offered the option "Turn Windows features on or off". Fortunately, this is very easy: click in the Cortana search bar and enter "Features".

If you have problems connecting to your FritzNAS or other network shares, you need to re-enable SMBv1 in Windows. However, this does not have to be the case, because the function should actually be switched off for security reasons.

My Windows 10 Pro with the latest update still supports the service and connects to SMBv1 shares without complaining. Windows 10 is also officially no longer able to do SMB 1, although this also depends on the Windows edition used and the update installed. With muCommander you can conveniently access SMBv1 drives in the network as usual. To connect, simply press (Control)+(K) and enter the connection information for the network device here. With this tool you can easily connect to an SMB share, even if it only supports the outdated SMBv1 protocol. One of the few that is functionally and visually correct and available free of charge is muCommander, which by the way is not only available for MacOS, but also for Windows and Linux. Important: Many MacOS programs access the MacOS base system for network functions, so you need a tool that has its own SMB support.

Otherwise, you'll have to bring out the heavier artillery and install a tool that still supports SMBv1 shares. First read the manual for your device to see whether, in addition to SMB, FTP, WebDAV or similar services that can be used for file exchange are supported. Unfortunately, if you want to address other shares, things get a little more complicated: The SMBv1 share may not have any other protocol like FTP that you can switch to. Then you can use a free FTP program like Cyberduck under the adress and your username and password on the FritzBox and they continues as a network share for home use use. Activate the checkbox "Access via FTP active". In order to open the FTP share of the FritzBox in the Finder, you must first go to the FritzBox user interface and select the Home network -> Storage (NAS) menu. FritzNAS or wants to use an older network device under MacOS Catalina and newer, does not have to wait until the implementation of newer SMB versions in the FritzOS FritzBox operating system: In addition to SMB, the FritzBox also supports FTP! This saves users who have stored important data on a NAS system, because FTP still works under MacOS 10.15.
