Review privacy settings and limit sharing to the minimum needed.

For Windows 10, see Microsoft's Windows 10 and privacy and ZDNet's How to secure Windows 10: The paranoid's guide. For other versions of Windows, do an Internet search for "privacy" and your Windows version.

Install and use anti-virus software.*

See the Viruses page for guidance. You may also use your own commercial product.*

Run the Microsoft Fix it tool for security settings

Run the Microsoft Fixit tool (or check Microsoft Support for specific instructions for these settings for your version of Windows):

  1. Turn on your Windows Firewall.* It is normally turned on by default.
  2. Check your anti-virus protection status
  3. Turn on Automatic Update to keep your version of Windows updated.
  4. Check whether you have the latest version of Internet Explorer installed.
Use BitLocker Drive Encryption (for laptops) to encrypt your computer's hard drive.

BitLocker is included in Windows. Check Microsoft Support for instructions for your version of Windows. (It is not necessary to encrypt desktop computers in secure locations, such as your home.)

Install U-M VPN (Virtual Private Network) software if you expect to use untrusted networks.

Untrusted networks include guest wireless in a hotel or coffee shop. Members of the U-M community can download and install the U-M VPN or the one appropriate for their campus. See Use a Secure Internet Connection.


Use a secure internet connection.

Secure networks include wired connections and MWireless.

Turn on the VPN if using untrusted wireless networks.

Untrusted wireless networks include guest wireless in a hotel or coffee shop. Most U-M users should use the U-M VPN. UMHS users should use the UMHS VPN. See footnote below.

Turn off optional network connections like Wi-Fi and Bluetooth when you're not using them.
Review wi-fi sharing settings and limit sharing to the minimum needed.

Only install applications from reputable software providers.
Be aware of where data is being stored and store sensitive university data only in approved locations.
  • Check the Sensitive Data Guide for services approved for use with sensitive data.
  • Many Microsoft applications let you share files using OneDrive (Microsoft cloud storage). Do not do this if you work with sensitive university data.
Be aware that certain types of sensitive data cannot be accessed or maintained outside the U.S.

 Some of these data type include Export Control, HIPAA, and FISMA. See the Sensitive Data Guide for details.

Before you sell or give away your computer, erase the hard drive. securely.
Report security incidents.

Detailed Security Instructions

Microsoft offers more detailed Windows security info and instructions:

* If you purchased a different anti-virus and/or security program with its own firewall that you use instead of the Windows firewall, that's okay. Just make sure that the firewall and anti-virus protection are turned on and that the software is regularly updated. We recommend that you use only one security program.

Additional Best Practices

Consider these additional options for enhanced security for your computer and the data maintained on or accessed from it.

  • Back up your data. Always keep a backup copy of files you do not wish to lose. Hard drives wear out and fail. Devices can be lost or stolen. The university offers several file storage options you can use. Check the Sensitive Data Guide to see which services are appropriate for certain types of sensitive institutional data.
  • Choose web browser security settings that protect your privacy and enhance security.
  • Be safe online. Learn about strong passwords, how to protect your identity, how to avoid phishing scams, and more.
  • Put a sticker on your computer with your name and contact information. This low-tech, practical step enables somebody to contact you if they find your lost computer.
  • Register your devices. The U-M Police Department offers a free laptop and personal electronics registration program to members of the U-M community to deter theft and assist in the recovery of stolen property.
  • Travel safely with technology. Take precautions when you are away from home to protect your privacy and the university's sensitive data.
