My grandfather always downloads the most scammy software you could possibly find in the web: - shady antivirusses - Help centres - Porn software and so on. I don't know how he gets it, he just asks me to remove it every then and now. I installed him firefox with ad & ublock, but that didn't got us any further.

I need a software that prevents him from installing new software and that only allows him to visit certain websites: or anything similiar to solve this problem.

Update: My grandfather uses Windows 10, he needs some windows tools that are not available for linux (Or hard to install at least).

Porteus Kiosk is a lightweight Gentoo-based Linux operating system which has been downscaled and confined to allow the use of one application only - the Firefox web browser. The browser has been locked down to prevent users from tampering with settings or downloading and installing software.

Porteus Kiosk is fast, small, free and secure. It's locked down by default. The only authorities capable of making changes are the kiosk owner (administrator) or the Porteus Team in case when kiosks are signed to the automatic updates service.

Windows 10 has a built-in kiosk mode feature, but kiosk mode in Windows 10 is transparently easy to circumvent if the user of Windows 10 has administrative privileges.

To configure kiosk mode, do the following:

  1. Open Settings.

  2. Click on Accounts.

  3. Click on Family & other users.

  4. Under "Set up a kiosk," click the Assigned access button.

  5. Click the Get started button.

    enter image description here

  6. Type a short, but descriptive name for the kiosk account.

  7. Click the Next button.

  8. Select a Microsoft Store app from the list.

    enter image description here

    Info: We're selecting Microsoft Edge, which includes additional configuration options, but the settings for other apps may be different.

  9. Click the Next button.

  10. Select the option that suits your environment. (In this guide, we're selecting "As a public browser," to configure a device that will be used by guests to browse the internet.)

    enter image description here

  11. Click the Next button.

  12. Type the web page address you want users to use for the home page, start page, and new tab page.

  13. Specify the time before Microsoft Edge restarts the InPrivate session if no one is using the device.

    enter image description here


  14. Click the Next button.

  15. Click the Close button.

Once you've completed the steps, restart your computer to start in kiosk mode.

If you want to exit the experience to shutdown or restart the computer, or access an administrator account, you'll need to use the Ctrl + Alt + Del keyboard shortcut to bring up the Lock screen to access the sign-in screen and power options.

  • Good Idea. I could remove his admin-rights and activate this kiosk mode. Just whenever He would want to do something that requires any rights, he would have to ask me... Commented Jan 24, 2020 at 8:18

I have a few elderly clients who use the computer for nothing other than web-based internet access. Obviously this requires a browser. For many of them, money is a concern as well. In two cases thus far, I performed a clean Ubuntu and instructed the client about navigation: this is Firefox, this is Shutdown and that was about it.

If word processing is involved, Ubuntu installs with a good office-compatible suite.

Certainly Firefox and Ubuntu are not bullet-proof nor virus-proof, but you may find that a good bit of protection accompanies this type of installation.

  • That's a good Idea, the problem is, he knows (More or less) his way around windows. A change might be too difficult for him. Commented Jan 24, 2020 at 8:04
  • That's one aspect of Ubuntu that makes it work (for some), it's generally the same actions. Depending on the version of Ubuntu installed, the close window icon is in the same location. The file manager is a file folder, Firefox is the same icon. You can install an admin account for you, and a user account for him to secure things even more.
