A DOS emulator such as DOSBox is often the practical way to try them; running the source in QBasic may work for many ASCII-saved programs, but compatibility depends on the individual program.
Why does GW-BASIC have trouble running on a modern PC?
GW-BASIC belongs to the DOS era. Microsoft’s 1986 GW-BASIC Interpreter User’s Guide specifies MS-DOS 3.2 or later for the documented interpreter. That requirement describes its intended historical environment, not a claim that every GW-BASIC program uses every DOS feature.
The key obstacle on many current PCs is Windows architecture. Microsoft says x64 and ARM versions of Windows do not support 16-bit x86 code, including DOS programs, through NTVDM. If the interpreter itself cannot run, a GW-BASIC program that depends on it cannot run natively through that mechanism either. A compatibility-mode checkbox cannot supply a missing 16-bit DOS environment.
Windows generation matters, too. Microsoft describes NTVDM as a component for IA-32 Windows NT editions that can run DOS applications, and says it is in maintenance mode. That older 32-bit behavior should not be mistaken for support on current x64 Windows.

- 3 1/2 Floppy Disk Reader: As most modern laptops and desktop computers no longer come equipped with internal floppy disk drive for reading floppy diskettes, this 3.5 inch external USB floppy disk drive is an excellent solution to reading and writing your old floppy disks as easy as a built-in floppy disc reader. Retrieve Your Memories, for all the people that grew up with floppy disks, this is a return to the past.
- Plug and Play Floppy Disc Reader: Just insert the floppy disk into the drive, then plug the USB type A/C connector to your computer and it will be automatically detected. Bring up Windows File Explorer, you will see drive A icon under "Devices and Drives", right click it and select open option, you could cut, paste, copy the files inside your floppy disks. Note: Please get power by the USB cable without using USB hub or USB extension cable, Insufficient power supply may cause malfunction
- Ultra thin and Portable USB Floppy Drive: With ultra-slim (Only 0.63inch thick) design and lightweight(Only 0.52Ib), you can easily carry and use this compact USB floppy disk reader to retrieve your wedding photos, childhood photos, favorite poetry, university graduation thesis, novel manuscript and favorite songsinside your floppy disks at anywhere, no matter in the office, at school, at home or during travel. It's a great gift idea for someone who have a lot of memories in the floppy discs.
- Broad Compatibility: This floppy disk reader is compatible with most PCs, laptops, and desktop computers with Windows 11/10/8.1/7/Vista/XP/2000 OS, but not compatible with Mac and Chrome. In Windows 11/10 systems, there has many show/hide options in File Explorer, so after opening "Windows File Explorer," you may not see the drive icon named "Floppy Disk Drive (A:)". Please open "Devices and Printers," right-click on the drive icon named "TEACV0.0" under "Devices," hover the cursor over "Browse Files," and then click on "Floppy Disk Drive (A:)," then you will see the contents of your disks
- Reminder: Not all of your disks can be read, which is due to their age, not the drive. Floppy disks were produced in the 1980s and 1990s and have a history of 30 to 40 years. Due to long storage times, some floppy disks may be corrupted, mouldy or dusty, so some of your floppy disks may not be successfully opened by our floppy disk drive, or the drive may initially be able to open some floppy disks but stop working due to dust on the disks. Therefore, please carefully check the status of the floppy disk before reading to avoid the drive stopping working due to floppy disk issues.
What can you try?
Run it in a DOS emulator
The community-maintained GW-BASIC project FAQ recommends DOSBox as an emulator option. It provides a DOS-like environment in which you can try the original interpreter and program. Success still depends on the program’s requirements, so test the specific program and any data files it needs; graphics, sound, or external hardware may introduce additional compatibility issues. The project’s guidance is not a Microsoft compatibility guarantee.
Try QBasic if you have editable source
The GW-BASIC project says QBasic can run most GW-BASIC programs saved as ASCII. “Most” is not “all”: inspect and test the actual source rather than assuming it will work unchanged. A tokenized program file is not the same as editable ASCII source, and dialect-specific behavior may require changes. See the project’s FAQ and download page for its guidance.

Use Windows’ troubleshooter for other compatibility problems
For general older-app issues, Microsoft recommends the Program Compatibility Troubleshooter in its older-app compatibility guide. It may help with some application problems, but it does not add 16-bit x86 support to x64 or ARM Windows.

The general DOS-versus-Windows mismatch explains many failures, but it does not identify the cause for a specific file. The program may depend on a particular GW-BASIC version, DOS behavior, graphics or sound features, a specific file layout, or connected hardware. To diagnose it, gather these details:
