Why Schools Might Be Wasting Money on Windows Interactive Displays

Some are, when a Windows computer is added to every classroom board by default rather than because a lesson needs it. Most of what a Singapore classroom display does is already covered by a Google EDLA-certified Android board: writing and annotating, wireless sharing from teacher and student devices, a browser for MOE's Student Learning Space, and apps from Google Play. MOE lists Android 13 or later with Chrome among SLS's supported setups. A Windows OPS module adds roughly S$1,000 or more per room, plus a Windows licence lifecycle, endpoint protection and another device for IT to patch. It earns that when a subject needs Windows-only software. At SourceIT, the LG CreateBoard 65TR3DQ (Android 14, EDLA) is S$2,587.50, and the cheapest Windows OPS module, the Avocor i5 Gen 11 OPS, is S$1,028.75 (listed 31 Oct 2026).

What does a classroom board actually need to run?

From MOE's SLS technical FAQ, LG, Samsung and Microsoft support pages, accessed 31 Oct 2026.

Why does the extra Windows hardware add up?

Because it is bought once per classroom and owned for the life of the board. As an example, adding the Avocor i5 Gen 11 OPS module at S$1,028.75 to 30 classrooms is S$30,862.50 before installation, management or replacement. The cost does not stop there:

• Windows has its own lifecycle. Windows 10 support ended on 14 October 2025. Windows 11 Pro gets 24 months of updates per annual version, and older modules cannot move to Windows 11 unless they have an 8th-generation Intel Core or newer and TPM 2.0.
• It is another computer to secure. A Windows module needs endpoint protection, patching and someone to own it.
• It may go unused. If the Windows source has to be selected and woken separately, some teachers will stay on the board's Android home screen, and the module sits idle. The pattern is described in Why Your Classroom's Most Expensive Technology Might Be Its Least-Used.

Buy Windows for the lessons that need it, not for every classroom that might one day.

When is Windows on the board justified?

• Windows-only software. Some subject tools, lab software, CAD and older installed programs run only on Windows.
• Full desktop applications. Teachers who rely on desktop Office features, add-ins or local files may prefer a Windows source.
• A school already managing Windows centrally, where an OPS module can join the same policies as staff laptops.
• Specialist rooms, such as computing labs, design and technology rooms or lecture theatres.

For these rooms, a board with an OPS slot lets the Windows module be added where needed and left out elsewhere. How the two combine is covered in One Screen, Two Operating Systems: Is Android + Windows OPS the Smartest Choice or a Support Nightmare?

What should schools check on the Android side?

1. The Android version. Google's October 2026 Android Security Bulletin covers Android 14 to 17 only. Boards on Android 13 now depend on the vendor for new platform patches, so prefer Android 14 or 15 for new purchases, and ask the vendor what it commits to.
2. EDLA certification, which brings Google Play and licensed Google apps. What EDLA does and doesn't promise is in Google EDLA Certified: Does That Actually Make an Android Smart Board Better?
3. Management. Who will push firmware and apps, and with which tool.
4. Login and data. LG's TR3DQ can delete files on a schedule and lock USB copying, which matters on shared boards.
5. Duty cycle and warranty. The LG TR3DQ is rated for 16 hours a day, 7 days a week.

School device choices vary too. MOE's Personal Learning Device programme lets each school pick its device type, and published examples include iPads, Chromebooks and Windows laptops. A board that shares from all of them, and runs SLS in a browser, suits that mix. The wider question of Android versus Windows is covered in Android vs Windows Smart Boards: Are Businesses Buying the Wrong Operating System?, and specific board comparisons in LG CreateBoard vs Samsung WAF.

Frequently asked questions

Do classroom interactive displays need Windows? Not usually. Writing, wireless sharing, a browser for Student Learning Space and Google apps all work on a Google EDLA Android board. Windows is needed for Windows-only software.

Does Student Learning Space work on an Android board? MOE lists Android 13 or later with Chrome 128 or later as a supported setup. A board meeting that, with Chrome installed, fits MOE's list.

How much does adding Windows to a classroom board cost? At SourceIT on 31 Oct 2026, the Avocor i5 Gen 11 OPS module with Windows 11 Pro is S$1,028.75 per board, before installation and management.

Which Android version should a school buy? Android 14 or newer. Google's October 2026 security bulletin covers Android 14 to 17, so Android 13 boards rely on the vendor for new patches.

Can a school add Windows later? Yes, if the board has an OPS slot. MAXHUB's E3 and U4 education boards and Avocor's S and E50 series list optional OPS modules; check the datasheet for other models.
