Sometimes things just happen and you have to laugh. So I decided I wanted to get back to working with the Windows 10 Insider previews (and Windows Server previews). This time I decided to use VMs rather than my working machine so that interruptions were minimised. I created a new Windows 10 VM and as […]
I have a bunch of files that I’ve downloaded to a specific folder. I need to unblock and rename files in that folder.

On Windows machines physical drives are divided into 1 or more partitions which are each divided into one or more logical disks. Linking disks, partitions […]

You can also use PowerShell to extract the information $uri = “http://www.officeholidays.com/countries/united_kingdom/index.php” $html = Invoke-WebRequest -Uri $uri $holidays = […]
A post on the forum about using a variable as a where clause looked interesting. What the user wanted to do was to define a variable that contained the filter to be used by Where-Object.
