Those listings describe the software and its reported compatibility, but they do not verify a current official publisher download or confirm SiSoftware’s current free-use terms. Check the publisher’s site for the release and license details before downloading or using it.
What Sandra Lite 31.137 does
Sandra combines system inventory with diagnostic and benchmark modules. Its information modules report detected hardware and software; its benchmark modules run specific workloads and return results. TechSpot lists areas including processor, memory, storage, graphics, network, and Windows information, along with CPU arithmetic and multimedia, file-system, removable-storage, memory-bandwidth, and network benchmarks. The exact modules available can vary by edition and release. TechSpot’s Sandra Lite 31.137 listing describes these capabilities.
Use inventory to see what Sandra detects on a computer, and use a benchmark to measure performance on the particular test it runs. A benchmark score by itself does not establish how fast a PC will feel in everyday tasks. For meaningful comparisons, use the same test and account for configuration and system conditions.
Is Sandra Lite free?
Third-party listings use labels such as “free” and “freeware.” TechSpot describes Lite as free for personal or educational use, but that is a directory’s description, not confirmed current publisher licensing. Verify the terms with SiSoftware before using the software, particularly for commercial or organizational purposes. TechSpot’s listing and ComputerBase’s entry describe the edition; neither is the publisher.

Version labels and release date
Directories identify the release as SiSoftware Sandra Lite 31.137. Some also label it “20/21-R26” or “2021.” ComputerBase and CHIP give a version date of October 30, 2023; Heise’s record was updated August 24, 2026, but an update to a directory record does not establish a new software release. These labels and dates come from third-party listings, not a verified current publisher release page. See ComputerBase, CHIP, and Heise.
Windows compatibility and the Windows 11 driver caveat
Third-party directories list Sandra Lite for Windows, including Windows 10 and Windows 11. ComputerBase also names x64 and ARM for those releases. These are directory compatibility claims, not an independently verified support guarantee for every device, architecture, or current Windows build. Check the release information and publisher documentation for your system before installing. ComputerBase and CHIP list compatibility details.

Why Sandra.sys may not load
TechSpot reports that Windows 11’s “Kernel-mode Hardware-enforced Stack Protection” can block Sandra.sys on some configurations. In that situation, Sandra may still run, but hardware detection can be reduced; TechSpot says some benchmarks may remain usable. This is a reported limitation, not a certainty for every Windows 11 computer or Sandra build. TechSpot also says there is no easy or immediate workaround. Do not routinely disable a Windows security feature just to load the driver; consult current SiSoftware documentation or support for guidance specific to your system. TechSpot’s listing is the source for this caveat.

The available listings for Sandra Lite 31.137 are third-party download-directory pages, not confirmation of an official or current publisher download. The searches available for this article did not establish a current official download page, nor that 31.137 is the latest release. Before downloading, look for SiSoftware’s own site and verify the version, installer, and current license terms there.
