With such a configuration, user interface enhancements and fast user switching are turned off by default. For comparable workloads, 64&nbsp;MB of RAM was then regarded as providing an equal or better user experience on Windows XP with similar settings than it would with [[Windows Me]] on the same hardware.

===Physical memory limits===
The maximum amount of RAM that Windows XP can support varies depending on the product edition and the processor architecture.
