Will compaq presario v2000 support windows 7

Almost everything will run 7 but how much you can use of what is in it depends on the hardware.

You can download a utility from Microsoft that will check hardware and software. It's called the Windows 7 Upgrade Advisor

It is a bit pessimistic but if you have a gigabyte of ram and a reasonable video card an enough free space almost any pc under 5 years old should work just fine.

If you want to run Windows 7 on your PC, here's what it takes:

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  
• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
  
• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  
• DirectX 9 graphics device with WDDM 1.0 or higher driver
