Hi Jeffrey,

I do this also whenever I install PowerShell... Just one (old) question though and I think this was already asked by Thomas Lee before:

1.) ngening takes few seconds (maximum half minute)... WHY on earth you do ngening on background and not during installation????

2.) You should update that script with IsInRole. If you run it in Vista, you get "Access denied" if PS is not elevated.

3.) This is important one :) Is there any way to speed up PowerShell loading time on Terminal Services\Citrix??? I mean systems where people keep logging on and off all the time??? Are there any tricks how to pre-load .NET or do something similar? This is very important question for all people that would like to migrate vbscript\batch logon scripts to PowerShell.

Thanks,

Martin

First : I'm a complete noob

I get : "You must have administrative credentials to perform this task."

How do I start powershell as root

or is there something like sudo?

thanks

An invaluable piece of information.

This has reduced the startup time on all four of my regularly used PC's to "blink and it's there".

Powershell was worth waiting for anyway ;-)

In Program groups, right click on the PowerShell item and "Run As Administrator"

Bug.

Ngen'ing is the trick.

It seems a little surreal that after so much time and energy is devoted to PowerShell in books, blogs, audio and video throughout 2007/2008; one should then discover such a fundamental suggestion from JS (of all people!). Surely there might be one place to find such tips - without wondering whether one had wandered the web enough to secure all relevant information ?

Anyhoo - as ever, Many thanx to the PowerShell team - I can't recall such fun since the '80s.

Regards

Andy.

I did this when I fist installed ps v1 & completely forgot about it when I installed it on my new computer (was thinking it was slow, but it never clicked).

Very glad you reminded me, but isn't this the kind of bug you should realease a windows update to fix?

Yeah, Wow, I didn't use powershell if little tasks as it too long to load vs cmd, now no problems.

Don't forget that on x64 systems, you need to use "Microsoft.NET\Framework64"

Installing Powershell on Win server 2008

Martin Feness — Thu, 24 Jul 2008 07:31:20 GMT

I have installed a test server, Win 2008, Enterpirse edition, build 6001 SP1 and whatever I do, I cannot get Powershell installed. On my XP-system, no problem.

Installation stops, saying there is not enough memory. It is 1,5 GB.

Anyone who can help?

Thanks

Martin

If you think your PowerShell startup is slow, or even if you think it is OK, follow the instructions

Martin,

PowerShell 1.0 comes in-band with W2K8. You need to turn it on using the server manager UI.

I have powershell v2 ctp3 installed on a windows 2k8 x64 machine. If I run a certain powershell script as Administrator...the execution time is less then 10 seconds...if I run the same script as LocalSystem ..the execution time is 30 minutes, I've run "ngen"..but there's not progress on it. Which can be the problem?

P.S. I run powershell with -nologo and -noprofile
