I’ve been updating my various environments from Windows Server 2012 RTM or Preview releases (build 9431) of Windows Server 2012 R2 to the final bits. On some boxes I just use my scortched earth policy of leveling the partitions and starting from scratch – others I will do an install and use the same partition. You get the following dreaded message – which you dismiss and move on.

Sure – I’ll just go and delete that directory after a while and go about my merry way.

Unfortunately it is not that easy.

In Windows client environments, you can just kick off a “disk cleanup” routine and have it removed – saving you a dozen or more GB of space. Unfortunately, that Disk Cleanup does not exist in Windows Server 2012 / 2012 R2 Full GUI install, unless you add Desktop Experience.

Fear not. Once you have confirmed you need nothing from that old c:windows.old directory structure, you can manually delete it, with a little bit of extra effort.

1) Download Junction.EXE from Sysinternals. I extracted and saved it to c:source. You will use this tool to generate a list of all the junctions that have to be removed.

2) create a reference file that lists all the junction points and symbolic links in use by opening up a command prompt, changing into C:source and running

junction.exe –s –q c:windows.old >junctions.txt

3) open up PowerShell ISE administrator rights and run the following script to remove all symbolic links and junction points in c:windows.old.

foreach ($line in [System.IO.File]::ReadLines(“c:sourcejunctions.txt”))
{
if ($line -match “^”)
{
$file = $line -replace “(: JUNCTION)|(: SYMBOLIC LINK)”,””
& c:sourcejunction.exe -d “$file”
}
}

Now it’s some simple taking of ownership, granting rights and deleting windows.old to get your space back.

4) to take ownership use

takeown /F C:windows.old /R /D Y

5) delete c:windows.old – you now have permissions and ownership.

How much space you get back will change based on your particular situation. My last run at this saved me 15.5 GB of space on my OS drive.
