Where to download Windows ISO files

For Windows disk image (ISO) files, you can get them directly from Microsoft via these links:

Office image files

Activating Windows

  1. Disable your third-party antivirus if applicable. For ESET, this will mean disabling real-time protection and HIPS.
  2. Windows will re-enable Windows Security, so we will need to disable it.
  • Head over to virus and threat protection settings, disable all the options
  • Head over to app and browser control, then into reputation based settings and disable all the options
  • For Windows 8/8.1, open Windows Defender and disable real-time protection.
  1. Open KMS Auto Net (do not unzip)
  2. Run the executable
  3. Select activation and pick Windows
  4. After activation, re-enable Windows Security
  5. Re-enable your third-party antivirus

Activating Office

For Office 2016, follow the same instructions as Activating Windows but upon running the KMS software, select Office.

For Office 2019, open powershell as an administrator and run this command:

irm | iex

From there, follow the guide selecting relevant numbers to activate Office.

For Office 2021:

  • Copy the script below into notepad and save it.

  • Rename the file to change the file extension to .cmd (instead of .txt).

    If you can’t see the file extension, head over to File Explorer and enable file extensions.

  • Run the script as administrator

If it fails to reach a server, try over and over. When successful, it will prompt you to read the MS Guides blog. Type Y if you’d like to read it or N for no.

Resolve ‘Get Genuine Office’ Warning

If Office prompts you to get genuine office, copy the command below, paste into text document and save it with a .cmd file extension.

"C:\Program Files\Common Files\microsoft shared\ClickToRun\officec2rclient.exe" /update user updatetoversion=16.0.13801.20360

What it does is downgrade the office to an older version that doesn’t have this warning. After which you can disable office updates otherwise it will upgrade back to a higher version with the same warning

Flash Windows onto a USB stick

All Windows Version

  • Connect USB stick to computer
  • Run Rufus software
  • Ensure the program has selected the correct external storage (your USB stick)
  • Click SELECT to pick your Windows ISO file
  • Choose between GPT or MBR partition scheme depending on the computer you want to install Windows. General rule of thumb, pick GPT for newer computers and MBR for older ones
  • Leave the remaining options as is.
  • Click START
  • Once complete you can eject the USB stick (except for Windows 8.1, continue with the guide below)

Windows 8.1 skip product key

By default, there is no option to skip adding a product key during Windows 8.1 installation but we can bring it back.

After flashing Windows 8.1 onto a USB stick, open file explorer and head over to /sources folder in the USB stick. Create a text file called ei.cfg and paste this.
