# Performance




Computer performance is how quickly and reliably a computer completes the work its user needs to do.




Practical performance guides and troubleshooting.


 


## How do I describe a slow-PC problem usefully?




Identify the task that is slow, when it happens and whether it affects one app or the whole PC. Observe CPU, memory, disk and available storage while reproducing it. A startup delay needs different checks from a slow website or one stalled application.




## How do I know a performance change helped?




Repeat the same task under comparable conditions and compare the result. Make one change at a time and keep a record of the original settings. Use the startup, processes or storage guide that matches the evidence instead of applying unrelated cleanup steps.
