@fdmautokj A glance at the help file would show you have answered your own question - look at the Random keyword. Simply use Random to generate a number and then tack it on to the end of the folder name.

I assume that OP have not to rename that folder just one time, but needs to generate many folders  with the same "prefix" (that is "update2016") followed by a suffix guarantee to be unique.
In this case using the random() function doesn't guarantee that the generated number is not been already generated, causing in that case a duplicate folder name.

I would suggest 3 possible alternatives:

1)  append the year + month + day + hour + minute + second + millisecond to your base foldername

$sFoldername = "update2016" & "_" & @YEAR & @MON & @MDAY & @HOUR & @MIN & @SEC & @MSEC

however this may generate duplicate filenames if you generate more folders in less than a millisecond

2)  another way is to use the _WinAPI_PathYetAnotherMakeUniqueName() function;

3)  or, as a third alternative, you can generate a unique ID using the _WinAPI_CreateGUID() function and append it to your folder name.

p.s.

Because AutoIt lacks a "DirRename" function, use the DirMove() function to rename a folder.

I believe _WinAPI_PathYestAnotherMakeUniqueName() is for files, not folders. Regardless, @fdmautokj as you can see there are many ways to skin the proverbial cat.

At first I thoug the same, but with this little test i saw it also works with foldernames..

#include <WinAPIShPath.au3>

; foldername to be renamed
$sFolderName = @TempDir & "\update2016"

For $i = 1 To 4
    ; create the "base" folder
    DirCreate($sFolderName)

    ; rename the base folder with a new unique name
    ; (actually we move the old folder to new one with a new name)
    DirMove($sFolderName, _WinAPI_PathYetAnotherMakeUniqueName($sFolderName))
Next

; show the result
ShellExecute(@TempDir)

Learn something new, I have only seen it used no files.
