This is fine, provided it's for personal use, and not commercial use.<br />
<br />
if the experiment, is only going to last less than 30 days, you could use the VMware Workstation trial, which lasts for 30 days for free.

In VMware Workstation Player free you can run or install as many VM's as you want. You can also run them simultaneously provided your hardware is up to it. Your problem could be the licensing of the OS you want to run as a VM. M$ OS's trial periods run out after some time.<br />
<br />
An alternative to VMware Workstation Player free would be Oracle's VirtualBox. This tool is OpenSource and free, and you can run it commercially too. In performance and features it is similar to VMware Workstation/Workstation Player Free.

I just need one so that all my setup done does not have to be redone when machine is formatted etc. so I want to try benefits of working on VM.<br />
Tried Virtualbox first. Very easy to use , free etc. <br />
Failed to connect USB (Lenovo A6000). Asked here and even on the official community. Seems it has a bug. Several unresolved questions like mine.<br />
Got advice from here and switched to VMware, Only concern was it should not expire after few months as I want it running long term,
</div>


<div>
What exactly was the problem with USB? What did you try to connect, how did you try the connection? I haven't encountered any USB connection problems with VBox.

Also as mentioned earlier the official site has several unanswered queries on the subject.

I have just tested this with a China Android Phone Clone. First on the not running VM I changed the USB settings to a &quot;new filter&quot;. Then I started the VM (Windows 7 running on a Windows 10 Host). Waited until I had logged in and everything settled down, then connected the Android SmartPhone to the USB. The VM searched for and installed a new driver (I didn't have to install any software), and then I was able to connect to the phone's memory, copy etc. So it works fine with VBox (just as it does with VMware 12 Workstation Player).<br />
<br />
It could be important that you wait until the VM is running before plugging the device in, otherwise the host OS would be using it and might not release it when you want to use it in the VM.<br />
<br />
The things I found on the VBox site were many years old and had been closed or resolved long ago for older VBox versions.

If I use VM Player just for single Virtual machine and require it for some experimental purpose only will it expire in some time. I intend to use the free version?

VM Player

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
