- Developer mode enables sideloading of apps UWP/MSIX and tools like Device Portal and SSH.
- It involves risks: more attack surface and the possibility of running unverified software.
- Installing unsigned apps is not the same as sideloading drivers unsigned; these require additional methods.
- Use temporary modes (advanced startup, TESTSIGNING) and revert changes when finished.
Windows 11 It includes a developer mode that opens the door to advanced tools, testing, and the installation of app packages outside of the usual channels.. If you are into programming, testing software or just want to experiment with features that are not available by default, enabling this option will allow you to do so. sideload of unsigned applications and access debugging and deployment utilities that are normally hidden.
However, this flexibility carries risks and it is important to understand what changes in the system, how to activate it and when to deactivate it.. Also, it's not the same install unsigned UWP/MSIX apps that load unsigned kernel mode driversThe first is addressed with developer mode; the second requires additional methods and a great deal of caution. Here you'll find a complete guide that brings together everything essential, from enabling and using developer mode to the mechanisms for dealing with unsigned drivers, their implications, and best practices.
What is developer mode in Windows 11?
Developer mode is a system configuration intended for programmers, testers, and advanced users.. When activated, Windows relaxes certain restrictions and enables development and debugging-oriented features that make it easier to test software in a real-world environment without necessarily going through the Microsoft Store.
Its star use is sideloading: allows you to install and run unsigned app packages (for example, .appx or .msix) that you download yourself or are building in your projects, without having to publish them to the Store.
- Installing apps outside the Microsoft Store: Running UWP apps and MSIX packages without prior validation in the store.
- Access to debugging and diagnostic tools: Integration with debuggers, emulators, and detailed logging to identify problems.
- Better options with WSL: the Windows Subsystem for Linux benefits from additional configurations and a more flexible test flow.
- UWP development and pre-release testing: ideal for validating and polishing your apps before uploading them to the Store.
- remote debugging: possibility of connecting your PC with other devices (mobile, IoT, other teams) to test apps directly.
How to activate developer mode in Windows 11
The process is quick and is done from Settings. You can open it with Win + I or from the Start menu.
Navigate to the developer area. Depending on the version or translation of your Windows 11, you will find it as Privacy and Security > For Developers or in some cases in System > For programmers / Area (or Space) for developersThe section name may vary, but the switch is the same.
Turn on the “Developer Mode” switch. Windows will display a safety warning explaining the potential risks of enabling this option. If you agree, please confirm with Yes. On certain devices you may request Reiniciar to apply necessary components.
Once enabled, you'll be able to install unsigned apps, use the Windows Device Portal, and access other development-oriented features.If you're working with Visual Studio, opening a project that requires these capabilities will prompt you to enable developer mode from a dialog box that links to the "For Developers" page.
What exactly does it enable: tools and services involved
Enabling Developer Mode installs feature packs and enables additional deployment and debugging options.These include services and firewall rules necessary for more advanced development scenarios.
- Windows Device Portal: A web interface for managing and deploying apps to the device. This is only enabled when you enable the “Enable Device Portal” option.
- SSH services for remote installation: when activating the Device discovery, the SSH service is configured and firewall rules are created to allow access. remote installation.
- Integration with Visual Studio: Projects that require it will be asked to enable the mode to deploy and debug applications on the same computer or on other devices.
Some flows also make it easy to work with scripts and automations.. Many developers adjust execution policies in PowerShell for testing, although it is best to manage it explicitly (e.g. by changing ExecutionPolicy) rather than assuming developer mode removes everything.
Common uses: sideloading and agile development
With this mode enabled, you can install unsigned .appx and .msix packages without going through the Store., which is ideal for validating internal builds, prototypes, and pre-release versions of your modern UWP or MSIX projects.
Remote debugging and testing on multiple devices (including IoT) are faster because you can connect devices, enable Device Portal, and use tools built into Windows without any extra configuration steps.
WSL and Hybrid Test Environments They gain flexibility, allowing you to switch between shells, services, and tools with less friction. This speeds up iteration, especially when debugging auxiliary services or local backends that interact with your UWP/MSIX frontend.
In case of using game engines or frameworks that deploy test builds, developer mode eliminates the need to sign off on each iteration, which greatly streamlines integration and testing cycles before a delivery milestone.
Risks and safety considerations
Enabling developer mode reduces security barriers by design. This implies that you can install unverified software, and if a malicious app is sneaked in, the potential damage is greater than in a blocked environment.
Additional network services such as SSH or Device Portal, if not configured properly, expand the attack surface. In work teams or portable that travel between networks, it is advisable to activate only what is essential and protect it with strong credentials.
More privileges for development and debugging tools assume that a malicious binary may attempt to escalate permissions. Minimize the risk by only installing software from trusted sources. solutions and turn off the mode when you don't need it.
