What are your system specifications?

For example, anything less than a true dual-core processor and true minimum of 4 GB RAM will result in a system running Win 7 you may not be happy with. Intel dual-core consumer cpu’s begin with Pentium D and higher, that to me, is the true minimum requirement for satisfactory operation of Win 7. If the processor can run 64-bit programs and has a memory controller built into the motherboard that can run 64-bit memory, then it is then possible to run more than 3.25 GB RAM. The sweet spot for Win 7 is 4 GB RAM. The more powerful and faster your system is, the more features built into Win 7 can run and become available and usable for you to use.

If you have a Pentium 4 hyper-threaded processor, where the second processor is a virtual core running within a single core, I wouldn’t waste my time with it. You’re not going to get the computing experience you should with such an obsolete system when running Win 7.
