kitzy f082237518 Add Lenovo System Update as a Windows FMA (#50339)
**Related issue:** Resolves #50324

Adds Lenovo System Update as a Windows Fleet-maintained app, from winget
`Lenovo.SystemUpdate` (5.08.03.59, Inno Setup, machine scope, x86-only).
Found in a customer's ManageEngine ServiceDesk Plus Windows deployment
catalog with no Fleet equivalent. Distinct from
`lenovo-dock-manager/windows`, which we already ship.

## Verification

- Installer SHA confirmed against a local download of
`system_update_5.08.03.59.exe` (`e66794dc…53e0d`), served from
`download.lenovo.com` — a pinned vendor URL, so none of the SourceForge
mirror trouble from #50322 applies.
- Registry `DisplayName` determined offline as a bare `Lenovo System
Update`: `innoextract --info` reports `AppVerName` when set and falls
back to `AppName`, and Inno writes that same value to `DisplayName`.
This installer reports no version suffix, unlike CrystalDiskMark in
#50322 which reports `"CrystalDiskMark 9.0.3"`. That is why the exists
query here is an exact match rather than a prefix.
- Icon extracted from the installer's own `Tvsukernel.exe` resource, not
sourced from the web.
- The uninstall script targets the Inno registry key directly via the
manifest's `ProductCode` (`TVSU_is1` — a key name, not a GUID) using the
`$PACKAGE_ID` substitution, rather than string-matching `DisplayName`.

## Two things reviewers should weigh in on

**1. The exists query deliberately omits the publisher.** House style
usually pins `publisher = '...'`, but the registry `Publisher` is not
determinable offline for Inno, and the validator's log prints only the
name and version — so I could not confirm it. A wrong publisher makes
the exists query silently never match while the validator still passes,
which is the exact failure mode called out in the FMA docs. `name =
'Lenovo System Update'` is unambiguous on its own. Happy to add the
publisher clause if someone can confirm the registry value on a real
Lenovo host.

**2. This may not be validatable on the CI runner.** Lenovo System
Update is a vendor tool for Lenovo hardware, and the runner is a generic
Azure VM. If the installer refuses to run on non-Lenovo hardware this
will fail the way Dell Display and Peripheral Manager did in #50020
(which was dropped for exactly this reason, and is being retried on a
client-OS runner in #50313). Leaving this in draft until the validator
reports.

Open-source platform for IT and security teams with thousands of computers. Designed for APIs, GitOps, webhooks, YAML, and humans.

A glass city in the clouds

What's it for?

Fleet gives you a single system to secure and maintain all your computing devices over the air. You can do MDM, patch stuff, deploy software, and verify anything, all from one place, across every OS your organization uses.

Fleet works directly with data and events from the native operating system, down to the bare metal. Strong diagnostics let you investigate errors on end-user devices and collect accurate audit evidence in minutes.

Get started

You can try Fleet out for yourself, or grab time with one of the maintainers to chat.

Is it any good?

Fleet is used in production by IT and security teams managing thousands of devices. Many deployments support tens of thousands of hosts, and a few large organizations manage 400,000 or more.

Supported platforms

  • Linux (all distros)
  • macOS
  • Windows
  • Chromebooks
  • iOS and Android (BYOD or corporate-owned)
  • Amazon Web Services (AWS)
  • Google Cloud (GCP)
  • Azure (Microsoft cloud)
  • Data centers
  • Containers (kube, etc)
  • Linux-based IoT devices

Infrastructure as code

Manage your fleet with GitOps, or use the GUI, REST API, webhook events, and the fleetctl command-line tool.

Linux support

First-class support for all major distros. Linux gets the same attention and visibility as macOS and Windows.

Visibility and compliance

Fleet can report on hundreds of attributes across your devices and ships with CIS benchmarks for macOS and Windows and comprehensive operating system, hardware, and software data. Check out the table reference documentation to see what's available.

Open by design

Fleet is open source and transparent about what it can and can't see. End users can verify exactly how the agent works and what data their company collects. Fleet collects only the data needed to manage and secure devices, not private activity like keystrokes, emails, or webcams.

Good neighbors

Ready-to-use, enterprise-friendly integrations exist for Snowflake, Splunk, GitHub Actions, Vanta, Elastic Jira, Zendesk, and more. Fleet also works with tools such as Munki, Chef, Puppet, Ansible, CrowdStrike, and SentinelOne.

Lighter than air

Fleet is lightweight and modular. You can use it for MDM without using it for security, and vice versa. You can turn off features you are not using.

Free as in free

The free version of Fleet will always be free. Fleet is independently backed and actively maintained with the help of many amazing contributors.

Longevity

The company behind Fleet is founded (and majority-owned) by true believers in open source. The company's business model is influenced by GitLab (NYSE: GTLB), with great investors, happy customers, and the capacity to become profitable at any time.

Fleet Device Management's company handbook is public and open source. You can read about the history of Fleet and our commitment to improving the product.

Chat

The Fleet community is full of kind and helpful people. Whether or not you are a paying customer, if you need help, just reach out.
