Hi,

sure, you sort after converting it to string, so it will sort alphabetically. Switch the order and sort for WorkingSetPrivate first, then do the select and it should be just fine.

cool, thanks it works, i am banging my head on another issue, task manager showing 26% memory for firefox, but by this calculation i get only 13%, task manager doesnt know maths. 790 MB in 6GB is close to 13 % but why it is showing as 26% , MS bugs me a lot

i got the answer for this as well...it calculates total process memory not physical memory..

For the sorting issue, you can ensure numerical instead of alphabetical sorting by converting values to integers inside the sort-cmdlet:

... | sort{[int]$_.ram} -descending | ...

This convertion is for sorting only and not given to the next pipeline position or final output.
