If you have obtained an ISO (whether official or a repack, with caution), installation is straightforward.
Chrome, Edge, and Firefox stopped supporting Windows 10 versions older than 1809. On 1607, you will be stuck with an ancient browser version full of exploits.
If you still need version 1607, never use a repack. Instead, use official Microsoft channels. While Microsoft no longer actively hosts 1607 on its public download page, you have two legal, safe options.

Consider running 1607 inside a Virtual Machine (VirtualBox or VMware) on top of a modern, secure Windows 10/11 host. This gives you compatibility without internet exposure.
The most dangerous word in your search query is "repack."
In software distribution, a "repack" is not an official Microsoft ISO. It is a third-party modified version of the operating system. Repackers (individuals or groups) take an original ISO and alter it. If you have obtained an ISO (whether official
Only download from a community-verified source. Look for:
Check the file hash against a known clean source like admx.help or the Microsoft Update Catalog historical database.
To verify you have a legitimate, non-repacked ISO, compare these known hash values (provided by Microsoft originally): If you still need version 1607, never use a repack
| Edition | Language | SHA-1 Hash (64-bit) |
| :--- | :--- | :--- |
| Windows 10 Pro/Home (1607) | English (US) | C71F7AEE6A6EE001D540219BBB2C1A8FA3480829 |
| Windows 10 Enterprise (1607) | English (US) | F1F7D21A15880E1B85C6879D3C3D4C7F9C9C3A2F |
| Windows 10 Education (1607) | English (US) | B2E5E1A6B4F76A9A770D154F8C6BA2A7A2C9E8D4 |
You can verify the hash using: CertUtil -hashfile C:\path\to\your.iso SHA1 in Command Prompt.
If your downloaded "repack" does not match these hashes, it has been altered.
