If you have a need to run multiple operating systems on one computer or test software products you’re interested in trying, VMware Workstation might be the solution for you.
VMware Workstation allows you to run multiple operating systems on one computer. What does that mean? On a Windows XP computer, if you have a lot of memory (I recommend a minimum of 2GB) and hard disk space (I recommend a minimum of 250GB), you can install VMware and it will allow you to run multiple operating systems under your main operating system – Windows XP. What?
For example, let’s say your computer is running Windows XP and you want to run Windows Vista as well to see what it’s all about. But you’ve heard so many horror stories about running Vista that you decide you just want to try it out and not upgrade from XP to Vista. Well, you would download and install VMware Workstation (purchase or download the evaluation version), then create a VM for Windows Vista.
What is a VM?
VM stands for Virtual Machine. A VM acts just like an operating system and it’s installed on top of your main operating system. It is a crazy concept to visualize at first but it works. This also allows you to install many other operating systems as well. Here are some that are supported by VMware Workstation:
- Windows – Most versions of Windows
- Linux – Ubuntu, RedHat, SUSE to name just a few
- Novell Netware
- Sun Solaris
- MS-DOS and FreeBSD
Once you have VMware setup and you install, let’s say Windows Vista, you’ll be able to run both your main Windows XP and Windows Vista on the same PC. Here’s a screen shot of Windows Vista – Home Edition, running in a VM on my main Windows XP PC.

Snapshot Manager
A really nice feature of VMware Workstation is Snapshot Manager. This feature allows you to install software that you might want to test but not commit to. For example, if you install Windows Vista in a VM, you can take a snapshot of it to preserve its state – a newly, clean install of Windows Vista.
Then, you could install some software that you want to test and play around with in the Vista VM. Once you’re done, you can use restore the VM back to the pristine install it was before you installed the software to test. This is what Snapshot Manager does. You can branch off in different directions using Snapshot Manager.
Another good example of this is when I wrote about Visual Basic 2008 Express Edition and Visual Web Developer 2008 Express Edition. I wanted to keep the two installs separate in a VM. So after I installed and was done testing VB 2008 EE, I reverted back to before I installed it and then I installed Visual Web Developer.
There are plenty of ways to use Snapshot Manager and I just scratched the surface on using it.
Another great feature is the ability to suspend a VM. If you suspend a VM it saves the state of your VM as is and allows you to shut VMware down. Below is a picture of Windows Vista – Home Edition, in a suspended state in VMware Workstation.

Very informative article, I wonder if it could also run windows 7? Is there any problems you’ve encountered with the software so far? Thanks for the tips.
Mike Rogers says
I run it on Windows 7, Mac and Windows XP. All run fantastically. I use VM ware not only for virtualized workstations, but for virtual testing servers for different configurations. I highly recommend it. Plus you can get the server versions for FREE as an alternative to VMWorkstation. However, I do use workstation because it lets you create a disk image that will run off a USB stick on any computer. Very handy when travelling to client sites.
Bill says
@Mike Rogers: Yes, love the USB stick capabilities. Thanks.

Will this software take up so much memory that it makes my laptop run slow?
Bill says
@Soccercoop: You’ll need a really beefed up laptop. Tons of memory and processor speed.

How to install 2 OS in a single system. One is 32 bit another is64 bit, as my machine supports 64 bit
Amit Sharma says
I have used virtual machine softwares. I used it when I needed linux for some time cause I always ran into problems installing windows and linux together on a hard drive.
Kristine says
I know this sounds goofy but have windows 7 now and I want to also run the old 3.11…can this be done? And without messing up my computer?
Bill says
Kristine » I run Windows 7 as the main OS and I use VMware. So I’d personally create a Windows 3.11 VM.
Julia says
Thanks for such an informative article, Bill. Great blog, too. One of the few I came across this week that has great, helpful content.
Sofia Loeb says
I have never thought about running multiple operating systems the way it’s described here, so I think this info is going to be real helpful for me.
Melissa says
This page is like a one-stop shop for technologically-challenged individuals like me. 😉 I really has a very productive time going through your article, Bill.

How many OSes can VMware run? I’m trying to run Windows 95 & 98 to run and download all my personal files and run old games. If you can provide a number of OSes that a high-powered Windows 7 desktop could run.
Bill says
Strongbad70 » I think it all depends on how much memory you have and the ultimate performance of each VM for what you want it to do. With that said, from VMware, sounds like you can create virtual machines with up to 8 virtual processors or 8 virtual cores, 2 TB virtual disks and up to 32 GB of memory per virtual machine.
Performance is the key, using growable virtual disks as opposed to a pre-allocated sized disk will impact performance a bit, turning off screen savers on the VMs, etc. There some tech documents on the VMware site you can read through for guidance.
If I was running Windows 7 with two VMs, one with 95 and one with 98, I would imagine they’d run okay with 4 GB of RAM. But it depends on their performance when games run since games can be graphics intensive.
VMware might have a tech document that explains a base formula but ultimately it depends on performance in the end.

hi ,
very nice article but i want to know
by useing vm can create multi user enviournment like windows xp os
as client and windows 2003/redhart linux as server and both are accessing each other.

I have heard about VM but i never tried it and also not yet but i would like to install Linux with my windows 7 operating system in my PC.
crystal paperweights says
i am a software engineer and currently i am running two operating system like window-xp and window-7. but now i will you link to get some knowledge about multiple operating system at same time
rack servers says
Yes,I have also 2 Operating Systems in my pc but it could not be supported.2nd thing is that my pc could not be supported internet.will u give me any information about both.Thanks…
Engraved Crystal Bowls says
I have never considered running multiple operating systems. Given that I can do this and it works well I think this info is going to be real helpful for me.
Engraved Crystal Vases says
I am amazed almost everyday with the things we can do now with computers. This can be of great value to many. Sometimes we need to upgrade to the newer operation system, but like working in the one we know best. Good writeup!

Thanks for sharing these important guidelines with us i am looking out for the same i have games which are not compatible with windows 7 suits too windows XP
Clay says
Can i create a VM ware image on a Windows 7 computer and then load in a ghosted image of my XP computer to this so that i would essentially have a Windows 7 computr and an XP image from my older computer?
