To check whether Windows 11 has a real update for your PC, open Start > Settings > Windows Update. Use the update status and offers shown there rather than a browser pop-up or an unfamiliar download asking you to run an installer. Microsoft says updates can arrive at different times on eligible devices, so an update not appearing yet does not by itself mean a prompt is fake. Microsoft’s Windows Update FAQ

Check for an update in Windows Settings

  1. Open Start > Settings > Windows Update.
  2. Review the status and any updates offered on that page. To check manually, select Check for updates if it is available.
  3. Install updates offered through Windows Update, following any restart instructions shown in Settings.

Windows 11 downloads and installs updates automatically, and Settings is the ordinary consumer route to check availability. Microsoft stages some rollouts, so eligible devices may not all receive an update at the same time. A delayed offer is not, on its own, evidence of fraud. Microsoft explains update availability and the Settings route here.

What you see How to treat it Why
An update listed in Settings > Windows Update Use this page to check and install Windows updates. Windows Update exchanges metadata over HTTPS and checks downloaded update files with digital signatures and hashes before installation. Microsoft documents these protections.
A browser ad, unsolicited pop-up, or unfamiliar site asking you to download and run an update executable Do not download or run the file. Close the page and check Windows Update in Settings instead. The external claim is not authenticated by Windows Update. Treating such prompts as suspicious follows Microsoft’s guidance on malicious downloads and deceptive software behavior; it is a warning, not a forensic test of a particular file. SmartScreen overview and Microsoft’s unwanted-software criteria.

Warning signs—and what they do not prove

  • A page or app falsely claims to be Microsoft, hides what it will install, installs without clear consent, or uses alarming or coercive messages. Microsoft identifies these as behaviors associated with unwanted software.
  • A claimed Windows release name or version number in a pop-up is not proof that the offer is genuine.
  • SmartScreen can help protect against phishing and malicious websites, applications, and downloads, but a warning sign alone does not establish that a specific file is malicious.

Microsoft does not provide a universal visual checklist that authenticates every update-themed prompt. When in doubt, do not use the prompt as your verification method: return to Windows Update in Settings. SmartScreen’s documented protections and Microsoft’s criteria for unwanted software.

If Windows says it is not genuine or needs activation

Investigate an activation or licensing notice through Microsoft’s genuine-Windows and activation guidance. Microsoft describes genuine Windows as software published by Microsoft, properly licensed, and supported by Microsoft or a trusted partner. Activation associates a product key or digital entitlement with a device’s hardware. These checks concern licensing and activation; they do not independently authenticate a separate update prompt.

When update behavior is controlled by work or school

On a PC managed by an employer or school, an administrator may control update policies and timing. If Windows Update looks different from what you expect or an update is delayed, ask the organization’s IT administrator before trying an external installer. Microsoft documents administrative control over Windows Update behavior; consumer instructions may not describe every managed device. Microsoft support guidance.
