I'm a longtime Mac user who fell in love with the SOQLExplorer's capability to run a query, double click a field on a returned record, modify the value, and thus update the record in Salesforce.
However I recently changed jobs which exclusively uses Windows (no admin privileges).
I have downloaded a standalone version of FuseIT.SFDC.Explorer which does have this capability and it works pretty well for the most part. However the only version I could find that doesn't require admin rights and has this capability is 3.4.16350.1 and it is using TLS 1.0. I'm assuming that when Salesforce shuts down that protocol March 2017, I'll have to find another solution.
