During a demonstration by Microsoft on July 27, 2006—before Windows Vista's [[release to manufacturing]] (RTM)—a notable incident involving WSR occurred that resulted in an unintended output of "Dear aunt, let's set so double the killer delete select all" when several attempts to dictate led to consecutive output errors;<ref name="GoodDemos">{{cite web |url=http://blogs.reuters.com/blog/archives/1991 |title=UPDATED-When good demos go (very, very) bad |last=Auchard |first=Eric |date=July 28, 2006 |publisher=[[Thomson Reuters]] |archiveurl=https://web.archive.org/web/20110521230956/http://blogs.reuters.com/blog/archives/1991 |archivedate=May 21, 2011 |accessdate=March 29, 2018}}</ref><ref name="MSNBC">{{cite web|url=http://www.nbcnews.com/id/14158843 |title=Software glitch foils Microsoft demo |author=[[NBC News]] |date=August 2, 2006 |publisher=[[Associated Press]] |accessdate=June 30, 2015 }}</ref> the incident was a subject of significant derision among analysts and journalists in the audience.<ref name="NeedsWork">{{cite web |url=http://www.infoworld.com/article/06/07/31/HNvoicevista_1.html |title=Vista voice-recognition feature needs work |last=Montalbano |first=Elizabeth |date=July 31, 2006 |publisher=[[International Data Group|IDG]] |work=[[InfoWorld]] |archiveurl=https://web.archive.org/web/20060805091528/http://www.infoworld.com/article/06/07/31/HNvoicevista_1.html |archivedate=August 5, 2006 |accessdate=June 26, 2015}}</ref><ref name="Stammers">{{cite web |url=http://www.techhive.com/article/126613/article.html |title=Vista's Voice Recognition Stammers |last=Montalbano |first=Elizabeth |date=July 31, 2006 |publisher=[[International Data Group|IDG]] |work=TechHive |accessdate=July 1, 2015}}</ref> Microsoft later revealed that these issues were due to an audio [[Gain (electronics)|gain]] glitch that caused the speech recognizer to distort the dictated words;<ref name="FAM">{{cite web |url=http://blogs.msdn.com/b/robch/archive/2006/07/29/682479.aspx |title=FAM: Vista SR Demo failure -- And now you know the rest of the story ... |last=Chambers |first=Rob |date=July 29, 2006 |publisher=[[Microsoft]] |work=[[Microsoft Developer Network|MSDN]] |accessdate=June 26, 2015}}</ref> the glitch was fixed before Windows Vista's release.<ref name="FAM"/>
