Test windows insider builds without risking your daily drivers using virtual machines and snapshots

Sandbox setup for windows insider builds testing

Testing Windows Insider Builds can be a great way to experience the latest features and updates before they are released to the general public. However, it can also be risky, as these builds are not yet fully tested and may contain bugs or stability issues that can affect your daily work.

To mitigate these risks, it is recommended to use a virtual machine (VM) to test Windows Insider Builds. This allows you to isolate the testing environment from your daily drivers and prevent any potential issues from affecting your main system.

Setting up a Virtual Machine

To set up a VM for testing Windows Insider Builds you will need a hypervisor such as VMware or VirtualBox. You will also need a copy of the Windows Insider Build ISO file, which can be downloaded from the Microsoft website.

Once you have installed the hypervisor and downloaded the ISO file you can create a new VM and install the Windows Insider Build. It is recommended to allocate at least 4GB of RAM and 2 CPU cores to the VM to ensure smooth performance.

Using Snapshots for Rollback

Another important aspect of testing Windows Insider Builds is using snapshots to create a rollback point in case something goes wrong. A snapshot is a saved state of the VM that can be restored at a later time, allowing you to revert back to a previous state if needed.

To create a snapshot simply pause the VM and select the snapshot option from the hypervisor menu. You can then restore the snapshot at a later time by selecting the restore snapshot option.

Isolation Practices

In addition to using a VM and snapshots it is also important to follow isolation practices when testing Windows Insider Builds. This includes avoiding the use of personal data and sensitive information on the test system, as well as avoiding the installation of untrusted software.

It is also recommended to use a telemetry control tool to limit the amount of data that is sent to Microsoft during the testing process. This can help to prevent any potential data breaches and ensure that your personal data remains secure.

Hardware Resource Sizing

When testing Windows Insider Builds it is important to ensure that your system has sufficient hardware resources to run the test environment smoothly. This includes ensuring that you have enough RAMCPU cores and disk space to run the VM and the test system.

A minimum of 8GB of RAM and 2 CPU cores is recommended, although more RAM and CPU cores can be beneficial for smoother performance. Additionally, a fast storage drive such as an SSD can help to improve the
