1.ReactOS is able to run Windows 2.softwareReactOS is able to run Windows 3.driversReactOS looks-like WindowsReactOS is a free and open-source Review collected by and hosted on G2.com.

it has a bit of similarity in installation procedure; cause well, yeah I first tried installing in Virtualbox too so in truth, the guide will work just as well. Review collected by and hosted on G2.com.

It lets me use windows as open source. Of course, it's easy to install and as it gives the old look of windows system that is also familiar. If you are a windows user, then you can use it easily. and it's free !! Review collected by and hosted on G2.com.

The first thing is that it takes you to old-time and it doesn't support a few applications as well. Review collected by and hosted on G2.com.

What I really like the most is that there are many other Linux distributions as well, which try to look like windows, but they are not that compatible like Zorin, Ubuntu-mate, etc. And on the other hand, we have React OS, which is really compatible can be a complete replacement for Windows. It supports most of the applications I was working on my windows machine earlier. Review collected by and hosted on G2.com.

The interface can be upgraded. It looks I am working on Windows XP with the power of Windows 10 Review collected by and hosted on G2.com.

As of me the most helpful for me is:

- Virtual sandbox for safe development and browsing

- Free of license restrictions

- Free of charge

- Very small image file to setup ReactOS, something about several hundred megabytes only Review collected by and hosted on G2.com.

- Not 100% polished and user friendly OS as Windows

- No x64 applications support, so you have to choose which version of app to install

- Also I had troubles with running Python on ReactOS - resolved only by installing earlier version of Python

- Hard to install on some specific devices, like Dell laptops. So you can spend several hours or even days on installing specific version of ReactOS on specific hardware. There are lots of videos on Youtube on resolving possible issues.

- No tools to check health of HDD/SDD Review collected by and hosted on G2.com.

Very interesting project : "an open source Windows". You know (and can check) that there are no code spying your data.

Obviously, it is a very big work: construct a compatible Windows, not a clone, from bare metal. Review collected by and hosted on G2.com.

While not all programs made for Windows can be ran flawless, a lot of them do.

It is not perfect, since the work is in progress, but considering the effort done, this project deserves a full 10 ! Review collected by and hosted on G2.com.

So, taking a look at ReactOS, it's a free and open-source operating system that has been built from the ground up to run native Windows programs. Review collected by and hosted on G2.com.

Things like wscript and cscript may not exist in reactOS. Corrupting the boot partition or MBR is still possible. Nothing will work 100%. (ReactOS will corrupt itself before we will get malware.)
