Microsoft Windows 10 Support ends on October 14, 2025
This means that effective October 14, 2025, GDM will no longer support ARM software on Windows 10 computers. For more information from Microsoft on this change, see: End of support for Windows 10 | Microsoft Windows
The word 'support' includes:
- Questions or problems with GDM programs on a Windows 10 computer.
- Attempting to send or receive any files (ARM, Word, Excel, PDF, etc) on a Windows 10 computer.
- Installing GDM software on a Windows 10 computer.
- Installing any software updates on a Windows 10 computer.
Windows 10 is 10 years old, so it cannot adequately support or protect modern computer hardware and software. GDM software uses Microsoft tools, and Microsoft only supports these tools when running on supported operating systems.
When upgrading from Windows 10 to 11, we recommend following the same steps for Migrating Studies and Settings to a New Computer. This ensures that your Favorites lists, report sets, editor views, etc. made within ARM are preserved through the upgrade process.

Take ARM to the field with ARM Mobile
ARM Mobile is a mobile app for taking notes in the field on iOS or Android devices.
Download ARM Mobile here: https://mobile.gdmdata.com/armmobilev7
ARM Mobile facilitates the core principles for quality research:
- On-site data entry
- Record assessments consistently across dates and locations
- Review data on-site prior to leaving – only quality/correct data points count in research
- Data transfer occurs in a professional manner – not transcribed from paper to computer, and not copied and pasted from file to file
