難道順著數字來不是天經地義的事兒么？
相關問題：網傳微軟跳過 Win9 發布 Win10 的原因是很多軟體用「if (osName.startWith("Windows 9"))」，這是真的嗎？
什麼叫跳過？ 我們來看看歷史
Windows 95
（96呢？97呢？）
Windows 98
Windwos 98 se (second edition)
（尼瑪還有 98se 為啥不是7 7se 8 8se？）
Windows ME (Millennium Edition)
Windows 2000 (NT5.0)
(之前還有 NT3.0 NT4.0 為何到了這一代就叫2000了！！！！)
Windows eXPerience
Windows Server 2003
Windows Vista
Windows 7
Windows Server 2008
Windows 8
Windows Server 2012
windows 8.1 / windows 8.1 with update
(坑爹嘛！「8.1 with update」是什麼破名字為何不直接叫8.2？）
那你憑啥就要求我就一定得叫 「windows 9」？？
Because 7,8,9！So 10！
在微軟OSG工作。昨天老大Terry M發郵件解釋了是因為Marketing的原因。一群人投票從10個名字之中選出來的。對這個名字People reactions有High Quality, Best, Numbers, 10 features, powerful等等

win9斬華雄
看Build
————————————我是分割線么————————————————6XXX的是Windows Vista7XXX的是Windows 7下面問題來了，微軟碼農為了交流方便，要求Build能被16整除，so
9XXX的是Windows 8-8.1
微軟發現，馬丹9XXX不小心被8.1用得差不多了於是依照目前TP版Windows的Build 98XX，估計到Windows 9發布那就是10XXXX了一個叫9的系統Build卻是10打頭，多不和諧，但是Build又降不下來
就決定是你了 WIndows 10！
附：了解Windows版本號(Build)的小秘密 為何你的Build這麼跳躍
賣萌完畢。
除了別人說的 Win95/98原因之外，還有一個原因：
Windows Vista：6.0
Windows 7：6.1
Windows 8：6.2
Windows 8.1：6.3
Windows 10：6.4
所以，Windows 6.4 叫做 9 也有點不合適吧 6+4=10 正好。
看不懂的評論我
Windows NT6.1是Windows 7。
Windows NT6.2是Windows 8。Windows NT6.3是Windows 8.1。
Windows 8.1就是Windows 9。
Windows NT6.4是Windows 10。
因為 Microsoft 使用 ⑨ 進位。
誰知道6和9幹嘛去了

原文
IN THE end, Microsoft fooled everyone. The replacement for its widely disparaged Windows 8 operating system turned out to be not Windows 9, as expected, but Windows 10. No explanation, other than marketing waffle, was given as to why the company should skip a release number. 「We know that based on the product coming, and just how different our approach overall, it just wouldn』t be right to call it Windows 9,」 Microsoft executive Terry Myerson told the press on revealing an early development version of Windows 10 (formerly code-named 「Threshold」) in San Francisco on September 30th. Within minutes, various presumed reasons had gone viral.
Was it to stop Apple continuing to steal a march with its tenth-generation operating system (OS X) for Macintosh computers, which have made steady inroads (albeit from a minuscule base) into Microsoft』s vast enterprise market? Could it have been to commemorate the ten releases of the various 32-bit versions of Windows to date? More fancifully, did the company avoid the number nine because the Japanese character for it (kyuu) could also be read as torture?
Or was it, as several software developers tweeted, because so many legacy applications first check whether the computer being used is running a version of Windows beginning with number nine (as in Windows 95 or Windows 98). Had Microsoft』s new operating system been called Windows 9, it was argued, serious compatibility issues could have arisen.Others wondered whether Microsoft was simply trying to distance its new operating system as much as possible from its unfortunate predecessor. With its touch-based approach, Windows 8』s radical interface using 「Active Tiles」 instead of the familiar 「Start Menu」 alienated users by requiring them to change their way of working too drastically. Meanwhile, employers balked at the cost of buying pricey touch-sensitive screens, as well as having to retrain staff to navigate around a computer desktop by touch rather than by keyboard and mouse.So much for the musings of the Twittersphere. There may have been grains of truth in several such suggestions, but Babbage prefers to believe the last one: namely, that Microsoft wanted to draw a line under its Windows 8 embarrassment, and show the world it had embarked on a whole new endeavour. From what was revealed last week, it is clear that Windows 10 is more—a great deal more—than just a tweak of the Windows 8 code-base, and ought, quite rightly, to be seen as a break with the past.
That departure from previous practice extends not just to the user-interface and underlying software, but also to the way Microsoft does business. Having been late to embrace the internet and slow to appreciate the significance of mobile and cloud computing, many might say such changes were not before time.Microsoft has learned much from its recent fumbles with Windows 8—as it did likewise when forced to rush out Windows 7 to replace its dismal Windows Vista. By all accounts, Windows 10 is to be all that Windows 8 would have been, had hubris not blurred the company"s vision. Spurred by the flop of Windows 8 and its half-baked update Windows 8.1, not to mention new management at the top of the firm, Microsoft has begun to take users" complaints more seriously than ever. This time, instead of insisting on a one-size-fits-all interface for Windows, whether on a phone, tablet, laptop or desktop, the operating system will be able to recognise which platform it is running on and adjust the screen size accordingly, while loading only those features appropriate. On phones and tablets, for instance, Windows 10 will slip seamlessly into the appropriate role, activating touch-sensitive gestures and all the small-screen features needed. On a laptop or desktop, the operating system will morph into something resembling Windows 7, navigated by keyboard and mouse with a welcoming Start menu at the bottom-left-hand corner of the screen. Whether used by office workers, home users, hackers or professionals, the aim is to let each choose the interface and experience he or she is most comfortable with.Despite Windows 10』s chameleon behaviour, all platforms using it will share the same unified code-base, and be capable of running the same applications, downloaded from the same app store serving all Windows devices, be they phones, tablets or computers. To make that happen, Microsoft has launched a far more comprehensive public-testing period than it has ever attempted before. Anyone can sign up for this Insider Program to receive a free preview copy of Windows 10, along with an app for registering suggestions and complaints. Be warned, though, the preview copy is very much a work in progress, and nowhere near stable enough for routine use. Many more tools and features will be added as, and when, they are deemed ready for public testing. The finished version of Windows 10 is not expected until later next year. What intrigues Babbage most, though, is that Windows 10 is, in a sense, the end of the line. There will be no follow-up; no Windows 11 in two or three years』 time. Nor will there be any blockbuster service packs in the meantime to correct buggy code and add missing features. Instead, incremental improvements for Windows 10 will be rolled out on a regular basis, perhaps every month or so, similar to the way monthly patches and bug-fixes for Windows have long been distributed.
By all accounts, these rolling updates will be an 「opt in」 service, so IT departments can control precisely what corporate users get their hands on. For consumers, having the option to update their systems automatically from the cloud will be a god-send. As it is, upgrading Windows installations can be a tedious, disk-shuffling affair, not for the faint of heart. But it need not be so. Macintosh users can upgrade their operating systems from one version to the next from Apple』s app store for free these days, using just a few clicks of a mouse. Linux users have been doing something similar for years.For Microsoft, the consequences of all this could be huge. Instead of treating each major release of Windows as a whole new product that existing customers must pay $120 or more to install, henceforth Windows upgrades are to be streamed to users as a service. Put another way, the company is moving from selling software licences to offering cloud-based services. Ironically, the best way to make that happen might be to give the basic service—rolling upgrades for Windows 10—away for free, rather than charge an annual subscription. That is not as radical as it may seem. Apple stopped charging Macintosh owners for upgrading OS X a year ago. Meanwhile, Microsoft already gives Windows upgrades away to users with devices that have screens of nine inches or less (ie, Windows phones and tablets). It also made Windows 8.1 available free to existing Windows 8 users. Presumably, it would continue to charge original-equipment manufacturers for installing Windows 10 on new devices.Free upgrades could also be the inducement that persuades the hordes of PC users who refuse to upgrade from older versions of Windows to do precisely that. Currently, Windows 8 and 8.1 account for little more than 12% of the PC user-base, according to Net Applications, a web-tracking firm. Meanwhile, 76% of PC users have remained loyal to Windows 7 or the even older Windows XP, despite all support for the latter having ceased last April. Such users have steadfastly refused to adopt Windows 8 because they find it too strange and demanding. Windows 10, with its return to traditional ways of doing things, should be a lot more to their liking.Ever since Windows 8 was released, sales of Windows 7 licences have increased rather than decreased. Businesses have continued to buy computers with Windows 7 pre-installed or have bought licences to downgrade Windows 8 machines to meet staff objections. However, come October 31st, Microsoft will stop selling copies of Windows 7 to system builders. It ceased offering retail copies a year ago. There are now over a billion recalcitrant Windows users around the world, waiting for a good reason to upgrade. Offering them a free licence for Windows 10, along with free rolling upgrades thereafter, would be the smartest move Microsoft could make to tempt them back into the fold. Even if only half were to take advantage of such an offer, the numbers involved would boost Microsoft』s cloud-based business spectacularly.In all it hopes to achieve, Windows 10 is quite the biggest gamble Microsoft has ever attempted. If the company pulls it off, then Windows 10 is set to become the most successful operating system of all time, eclipsing even the legendary Windows XP. Babbage relishes the thought that the coming version of Windows may well be the end of the line—especially now it seems to have been built not merely for replacement, but for continual evolution. That is precisely how many other things in life ought to be designed.
關於windows10的命名，謠言多，闢謠的更多，之前我和諸君一樣，也信以為真了，直到前兩天我看了一條新聞，才發現這是宿命的對決！
據The Verge報道，微軟開發者業務高管傑瑞·尼克遜(Jerry Nixon)在本周的Ignite會議上表示，即將發布的Windows 10系統將成為最後一個版本的Windows，其仍處在全力開發中。
是的，windows10是最後一個版本，但系統總要更新，更新的版本怎麼區分呢？
windows 10.0-windows 10.1-windows 10.2……
還沒看出端倪嗎？
OS X 10.0-OS X 10.1-OS X 10.2……
1997年，喬布斯取代阿梅里奧，成為蘋果的臨時CEO，帶領瀕臨破產蘋果走向復興之路。1998年，蘋果推出iMac，用的就是全新的系統，OS X。穩住陣腳後，蘋果發布了一系列革命性的產品：ipod、iphone、ipad。
目前微軟在移動互聯網的處境，同樣不容樂觀。但windows10擁有逆天的平台整合能力，無疑是個大殺器。對手從哪裡爬起來，就把他從哪裡乾死，windows這麼命名，也是和OS X、IOS較上勁了。
windows10能否從OS X、IOS手中奪得用戶的認可，PC+Lumia+Surface能否成為最完善的雲工作平台，諸君拭目以待。
win8.1又稱win9
微軟為了防止自己的產品看起來很傻，所以特地跳過了⑨這個數字
首先，這是個好問題。
官方比較正式說法：13年微軟公關代表Cheryl Tunt曾表示：「Windows 9內部測試版本異常成功，我的意思是說它超過了Windows 8，大家都知道Windows 8近乎完美。在經過微軟C級高管的討論後，決定不再驚動這些成功，於是讓Windows 9保持原樣。現在，微軟正在開發Windows 10，它會向公眾發布。」（大家真的覺得win近乎完美么？）
官方比較不正式說法：沒有！
官方非常不正式感覺在逗你玩說法: 「Windows 10, because 7 8 9.」這要用英語讀出來789 = seven ate nine（7吃掉了9）
民間邏輯推理說法：if(version.StartsWith("Windows
9")) {
/* 95 and 98 */} else { 「」}在當年開發的一些軟體中，曾經用相關的函數檢查操作系統版本，而Windows 95和Windows 98，以及「Windows 9」前面的字元部分一致，由於當年開發的應用軟體考慮並不周全，因此可能導致錯誤和問題。換言之，當年的程序員判斷，如果操作系統名稱中包含有「Windows 9」，則判斷為是Windows 95或者Windows 98。由於這些軟體沿用多年，已經無法為新版系統修改代碼。如果微軟使用「Windows
9」，將導致大量的歷史遺留軟體集中發生問題。
民間引述爆料說法：國外媒體WindowsCentral 爆料，在Win10里運行一款可以顯示設備詳細信息的免費應用《Belarc Advisor》， 系統全稱顯示為
Windows 9 Professional（x64）（build 9860）。
民間胡言亂語說法：Windows Vista：6.0
Windows 7：6.1
Windows 8：6.2
Windows 8.1：6.3
Windows 10：6.4 這樣剛剛好！
因為⑨啊
因為代碼里太多判斷版本是否為98或95的。。。而溫9版本也是9開頭。。不想改了。。就直接上是10

據一位自稱為「微軟開發人員」的網民稱，下一代操作系統之所以未被命名為「Windows9」，是為了避免與Windows 95和98發生衝突。
微軟本周二發布了下一代Windows操作系統，令業界意外的是，它不叫「Win9」，而叫「Windows10」。微軟為什麼要直接從Windows8跳到Win10呢？
對此，業界眾說紛紜。有分析人士稱，微軟此舉是為了與Windows 8劃清界限。由於Windows 8並不是很成功，微軟希望通過直接跳到Windows 10，讓消費者感覺到與Windows 8沒有多大關係。
還有分析稱，微軟歷史上共有10個主要的Windows系統，取名Windows 10是為了紀念這一歷史時刻。但有反駁者稱，那應該叫「Windows 11」才對。
還有業內人士稱，微軟希望加快Windows版本發布速度，以此推動Windows最終免費。微軟印尼高管德里斯·迪安特洛(Andreas Diantoro)稍早些時候曾表示，下一代Windows面向Windows 8用戶免費。
但上述解釋都沒有一位自稱為「cranbourne」的微軟開發人員的解釋合理。cranbourne在社交新聞網站Reddit稱：
「內部傳聞顯示，早期測試結果顯示，大量第三方開發者用下面這樣的代碼來判斷Windows 95和98：if(version.StartsWith("Windows 9")) { /* 95 and 98 */ } else {」
也就是說，開發人員在使用：「如果版本號始於Windows 9時，就將其視為Windows 95、98或其他。」這意味著，下一代操作系統如果被稱為「Windows 9」，則可能被第三方軟體識別為Windows 95或98。同時，第三方軟體還可能無法正常運行。
為避免出現這種不穩定因素，微軟只好將下一代Windows命名為「Windows 10」。
對於這種說法，有微軟前員工稱：「我曾在Windows兼容性團隊工作過，對於cranbourne的說法，我表示支持。」
而微軟發言人對此表示：「Windows 10代表著Windows轉向新的做事方式，這不僅僅是名稱上的變化，而是將被下一個10億用戶使用的新Windows。」
