问题 Having failed to get PowerGUI to work properly I've fallen back on PowerShell ISE. However if I run this as Administrator it won't let me set any breakpoints. If I launch as normal (my login is a member of Administrators) all is well but because I need to script some tasks that require full administrator rights this is no good. I have saved the script as a proper file (i.e. it's not "untitled1.ps1") but no joy. I'm running Windows 7 x64 Ultimate. Strangely this doesn't seem to be a problem on

问题 This is basically a duplicate of this question, but the accepted answer was "no" and I would like to keep this question open until getting an actual answer instead of accepting "NO" and giving up. Stephen Rose told me via Twitter DM to use PowerShell to start and stop Virtual PC VM's and do things like run installations, automatic updates and virus scans, but he hasn't yet responded to my request for any links to resources that describe how to do so. I've started learning PowerShell, but I

问题 I encountered a bug in a script I wrote this morning where I wasn't getting an output from my Select-String expression. After a bit of playing I realized that this expression would not return the value of my match in v2.0 but would in v4.0 where I originally wrote it. ($log | Select-String "\[CIsoCreator\] Creating iso file" -AllMatches | Select-Object -ExpandProperty line -Last 1 | Select-String "([A-Z]\:)(.*\\)*.*\.iso").matches.value After trying a few things I ended up with this which
