1. Licensed NTLite allows you to configure BypassTPM and other HW compatibility checks in the Settings. Free users have to do more work, and must load a registry file which does the same thing from Registry.
If you don't want to use a Microsoft Account as your logon, use the Unattended mode to create a new Local user. Unattended mode bypasses all the signup screens, and disables OneDrive folder sharing.
2. Disabling SecureBoot is a function of your PC's BIOS settings.
3. When you load an image, NTLite extracts the files to a temporary folder. Select the loaded image, and right-menu "Explore mount directory" then a File Explorer window will appear. You can copy files to the temporary folder, which will be the top of C:\
4. Free NTLite can delete unwanted images from a multi-edition ISO distribution. Download the ISO from MS, or use MCT to create a local file. Use 7-Zip or another archive app to extract the ISO's contents to a local folder. Load the ISO folder from Image.
You have two options:
Select one image at a time, and right-menu -> Remove.
Or select one image and export to WIM. After the single edition is exported as install.wim, move the saved file and override the ISO folder's existing sources\install.wim file. From the Image screen, click on the Refresh button and NTLite will rescan the replaced WIM.
5. From the Components screen, you can remove unwanted keyboards and language files you don't need.
6. Be advised, since you're on W7 platform -- NTLite cannot install W11 updates for you. The first time that Windows Update runs, it will probably download the current Monthly Update and install it. This may take a while. Doing image updates on a W10 or W11 system would avoid this hassle, but in your case this will happen as it should.
There's more exact details than that, but that's a summary of what you can expect.
