Updated 3/23/15 Fixed Windows 2000 Tags (both Server and Workstation) - Thanks Boyd!

Updated 1/6/15 adding Windows 8 Tag per request

Updated 8/19/14 with new more comprehensive Windows RegEx Strings!


This is an incomplete list. Please help out by commenting and I will try to add any helpful regex provided/requested.

Testing your regular expression

You can use the RegExr to check your regular expressions. RegExr has a character limit so I split up the identified operating systems into two links.

  1. RegExr prepopulated from 3com to Linksys Wireless
  2. RegExr prepulated from Linux to ZOT Print Server


Note: Case-insensitive option should be checked.



Contains this and that

Name contains "string1" AND "string2" then apply tag:


Contains this but not that

Name contains "string1" BUT NOT "string2" then apply tag.


Does not contain this

Name does not contain "".

Exact Windows OS Matches

Note: the following regex Strings are designed to only identify definitive OS matches in Qualys, i.e. those that have been scanned authenticated.  As such, it is recommend you also include a tag for "Windows Undefined" as listed below as part of your tagging hierarchy to capture all potential windows hosts.  Remember to check "ignore case" for all tagging rules below.


Windows Undefined (e.g. muti-match)

Accounts for mutiple windows matches with at least one "windows"  e.g. foo / bar / foo

Regex =

^Windows .*/((?!\/).)*


Windows Server 2003

Regex =

^Windows .*(2003)((?!\/).)*$

Windows Server 2008

Regex =

^Windows .*(2008)((?!\/).)*$

Windows Server 2012

Regex =

^Windows .*(2012)((?!\/).)*$

Windows Server 2000

Regex =

^Windows 2000 Server((?!\/).)*$

Windows 7

Regex =

^Windows .*(7)((?!\/).)*$


Windows 8

Regex =

^Windows .?(8)((?!\/).)*$


Windows 2000 (workstation)

Regex =

^Windows 2000 (?!Server)((?!\/).)*$|^Windows 2000$

Windows XP

Regex =

^Windows .*(xp)((?!\/).)*$


General Windows OS Matches

Note: This section includes more broad matching examples if you prefer to capture more hosts by TCP IP fingerprint + OS Identification.


Windows Server 2003

Regex =

^Windows Server 2003((?!\/).)*$|Windows 2003


Examples regex works on:

Windows Server 2003 64 bit Edition Service Pack 1
Windows Server 2003 64 bit Edition Service Pack 2

Windows Server 2008 R2
Windows Server 2012
