I notice you're looking for a Windows 10 Pro Version 1809 (64-bit) ISO.
However, I need to give you a critical warning before you proceed:

4. LTSB/LTSC Consideration
If you are downloading 1809 because you want a "lighter" version of Windows 10 without the bloatware (Candy Crush, etc.), you might actually be looking for Windows 10 Enterprise LTSC 2019.
- LTSC 2019 is based on Version 1809.
- It does not include Microsoft Edge (Legacy), Store, Cortana, or pre-installed apps.
- It is favored by gamers and users who want a stable, non-intrusive OS.
Summary: The most helpful features of 1809 are Clipboard History and Dark File Explorer. If you proceed with this installation, ensure you are on the "November Update" build to avoid the file deletion bug.
