Suggestion about VMWare

[lucius100]

I want to run certain software in vmware , need about 10-20 virtual pc
but currently i use 6 win xp in vmware with 128 ram and 1 core.
My pc Spec , Core 2 Quad Q6600 with 4 gb ram , and it takes 92% of my 4gb ram.
Is there any way to run that software with more ightweight OS ?
the closest example i can give is running ccleaner in 1 pc, and i want to run it in 10-20 pc 

I read VMWare server , VMware vcenter , vsphere, but don't know how that works 
Hope someone understand this question

What is the host OS? 

Why do you need 6 win xp in VMware?   

How many VM (virtual machines) do you need, or think you need, to run at the same time?

What does the following sentence mean?:

My pc Spec , Core 2 Quad Q6600 with 4 gb ram , and it takes 92% of my 4gb ram.

Do you mean your host OS, running alone, consumes 92% of memory?  4GB of RAM is a rather low amount of physical RAM for what you're trying to do.

the closest example i can give is running ccleaner in 1 pc, and i want to run it in 10-20 pc

I could be wrong but I believe you would need to install CCleaner, or any app, in each of the VM's.

I don't think you're wrong on this...

My host OS is Win 7
If possible i need about 10-15 Win xp in vmware .
And yes i only have 4gb ram ,
install ccleaner in each vm is the example , i and my friends want to  test some programs that we create ourselves and it's light weight as ccleaner only 
so it's not possible with 4 gb ram ?

at first we try with sandboxie and the program itself is conflict with each other, so we use vmware, and it works great but it consume more resource than we expected

Do you want to run all of them at the same time?  That will either work very poorly or not at all.  Back in 2011, I had a VM for Linux Ubuntu installed on my old Pentium 4 with 4GB of RAM and running even that one VM would get a bit sluggish if I simultaneously had several programs, including a browser with multiple taps, open in Windows 7 and then switching back and forth between Win 7 and Ubuntu.  So, if I wanted to mainly use Ubuntu for awhile, closing open programs in Win 7 worked best. 

So, if you're thinking of running 10-15 Win xp in vmware all at the same time, I'd say forget it.  I'm sure you will have to limit the running of VM's to 1 or 2 at a time, for all practical purposes.
