A software that can help you in this matter is Sandboxie. This means running the program as you normally would, but using an isolated environment which automatically isolates all the program's settings from the rest of the system, not allowing it to do any harm. Thus, running the program in a sandbox would be a very good idea. You don't really know how safe that program is and if it contains spyware or not. This Community post contains some additional information.Let's say you are a software enthusiast and you want to try a new program. However, registration is required – due to US export regulations. Sandboxie Version 5.31.4 has been available for download as a 32- or 64-bit version for Windows 7 to Windows 10 on this website since September 10, 2019. If you still have a Sandboxie license, you still have to switch to the 'free version'. In any case, Sophos announces that they have remove all restrictions on the unlicensed version with the new release. Personally, I think that Microsoft's decision to add the Windows Sandbox to Windows 10 Professional also played a role in Sophos' decision. They can continue to maintain the open source tool. It is commendable that Sophos is not simply letting the tool die, but is planning to put its further devlopment in the hands of the user community. Sophos mentions that the decision was made under cost considerations, as the tool has probably never been a significant part of Sophos's business, but on the other hand they had to maintain the software. Sophos is releasing Sandbox as a free tool and plans to make it open source.

The Sandboxie website now has the following information (thanks to Ralf for the hint): Since then, I haven't been tracking what happened to Sandboxie, so I didn't realize it was being bought by Sophos. With snapshots I could always reset the guest operating systems to their original state. A short time later the program became fee-based – and since I often ran into issues, I begun using virtual machines for my tests. However, at some point I ran into more and more into a situation where Sandboxie failed or the software could not be installed or used. You could test software and then uninstall it without leaving any traces, files or settings. I myself used Sandboxie under Windows XP for application virtualization. Sandboxie therefore enables you to test software and later uninstall it from the system without leaving any traces. This prevents unwanted changes from being made to personal data, programs, and applications that are safely stored on the hard drive. Sandboxie's isolation technology separates the installed programs from the underlying operating system.

Sandboxie takes control when installing the application and isolates all file and registry accesses and redirects them to separate files. Sandboxie is an application isolation program that allows you to run other software under Windows in a controlled environment.
