The history of bugs affecting Windows 10 is not new. The Windows update of May 10, 2019 brings with it an infinite series of problems.

Microsoft recently confirmed that the cumulative update of Windows 10 KB44979797936 causes problems with the Windows Test Environment.

The company says that insiders of Slow, Fast and Release Preview Ring may have problems starting Windows Sandbox. Microsoft has listed the bug on its support page.

It was confirmed immediately after many users started reporting the problem online. This error only affects Windows May 10, 2019 (version 1903).

Therefore, if you are one of those who have encountered a similar problem, it is recommended to simply uninstall the update.

Some of the most important changes are:

• Provides protection against a new subclass of speculative runtime vulnerabilities called microarchitectural data sampling for 64-bit (x64) versions of Windows (CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130). Use the registry settings as described in the Windows Client and Windows Server articles. (These registry settings are enabled by default for Windows Client OS and Windows Server OS editions).
• Fix a problem that affects Internet Explorer performance when you use roaming profiles or do not use the Microsoft compatibility list.
• Fixes a problem that can make the text, layout or cell size narrower or wider than Microsoft Excel expects when using MS UI Gothic or MS PGothic fonts.
• Adds “gov.uk” to the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge.

Microsoft Windows Sandbox

The Windows Sandbox is a temporary Windows 10 virtual machine that can test everything from potentially dangerous programs, web browser extensions and suspicious or dangerous websites in a completely isolated desktop environment.

Using the Windows Test Environment allows users to avoid contaminating their accounts if the programs or extensions tested exhibit malicious behavior. The Test Environment is the ideal choice for users looking for a simpler alternative to more complex programs such as VirtualBox, Hyper-V or VMWare.

However, it is also important to note that Hyper-V is also activated after the sandbox is activated, which prevents both VirtualBox and VMWare from running on the computer.

We also provides detailed instructions on how to use the Windows Sandbox to ensure online security, as well as a list of improvements that Microsoft could make to make this feature more user-friendly.
