An enthusiastic user of the IBM ThinkPad T43 has shared an impressive feat on Reddit, revealing that they can install nearly all versions of Windows, spanning from NT 4 to 10 22H2, complete with driver support, all without the need for virtual machine technology. This 2005 model, cherished by retro tech aficionados, stands out as IBM’s last design before the company transitioned to Lenovo ownership. The ability to run 26 years of Windows operating systems undoubtedly enhances the allure of the T43.

MatiHalek, the Redditor behind this remarkable achievement, documented their journey with a gallery of ten screenshots showcasing various Windows iterations, primarily highlighting the System > About control panel. This visual timeline offers a nostalgic glimpse into the evolution of the Windows user interface over the decades.
However, Mati’s approach was not a straightforward experimental process. Upon acquiring the laptop, they found it pre-installed with Windows XP, prompting them to dual-boot Vista alongside XP. They subsequently navigated the upgrade path from Vista to Windows 7, then to 8, 8.1, and finally to Windows 10 RTM. The recent Windows 22H2 update necessitated a clean installation, but modern operating systems do not seem to ignite Mati’s enthusiasm. Afterward, they opted to wipe the hard drive and multi-boot Windows 98, NT 4, and 2000, expressing a preference for this trio of 20th-century operating systems, likely due to their responsiveness on the T43’s hardware.
IBM ThinkPad T43 hardware
The ThinkPad T43, as previously mentioned, marks the end of IBM’s laptop production before Lenovo took over. Originally shipped with Windows XP, it debuted just months before the arrival of Vista.
Key components of the T43 include:
- Intel Pentium M processor
- ATi Mobility Radeon X300 or X300SE graphics
- 14.1-inch screen with resolutions up to 1,400 x 1,050 pixels
- Support for up to 2GB of DDR2 RAM
- Storage options ranging from 40GB to 100GB HDD
- Connectivity options including Wi-Fi, Bluetooth, Ethernet, and modem
- Ports featuring 2x USB 2.0, a parallel port, VGA, S-Video, a PC Card slot, and a docking station port
Beyond its technical specifications, the IBM ThinkPad T43 has garnered acclaim for its robust build quality and exceptional keyboard. While it may not be lightweight by 2026 standards, tipping the scales at approximately 2.3 kg (5.1 pounds), it remains a beloved choice among those who appreciate its legacy.
For readers who still hold fond memories of the IBM ThinkPad T43, the question arises: do you continue to use an older version of Windows like Mati, or have you transitioned to alternative operating systems such as Linux?
