Not even close. I'm not sure what relevance you associate with sorting by usage, but here is how GW free stacks up on my 2nd gen i5 laptop having 4MB RAM running Windows 7 x64 running 92 processes. Total memory usage is ~2.4GB. I assure you the GW metrics for my other 7 and 10 systems are nearly identical. Your memory usage is extreme compared to mine. Given the general unpopularity of GW by the rank and file members here and blunt disapproval by some, I think your troubleshooting efforts should be redirected to the GW forum. There are just not enough users here to present advice much beyond best guesses. Your focus on the private working set is insufficient in gathering data toward your resolution. You should enable some other columns, the two shown in my screenie and Commit Size. Good luck.
