曲奇餅魔術在窗口之後居住隨員安置者

宣佈窗口居住隨員在同日作為新 iPod接觸由God製作也許不是最明亮的想法，但是窗口居住仍然設法由得到一些關心通常嫌疑犯. 炒作是在這個統一的安置者附近毫不奇怪哪些確切地做什麼標籤更認為和沒什麼。我決定給它旋轉，但驚奇由沒有什麼它做了，但怎麼。

為已經未嘗試的那些，您指向您的瀏覽器 http://get.live.com/WL/ 并且您將遇到這個飛濺屏幕。起初，它也許看似您必須完成對下載能够存取的一個傻的』標誌』形式，但您實際上請求選擇什麼您在隨員想要安裝。我認為對我自己，「是整潔的oh。我選擇什麼我在網頁想要安裝」。然後我考慮，「怎麼實際上做此工作？」

窗口居住安置者在按以後「安裝」，您請求下載安置者的可執行。這時，我開始想知道這可執行是否莫名其妙地動態地引起或被預先包裝安裝我選擇仅的事，然而我亢奮點擊了所有下個按鈕，直到它最終開始安裝。毫不奇怪，它只下載了并且安裝了我選擇的應用。什麼它，它運作。

不滿意與「它正義工作」，我決定進一步調查。 I首先分析HTML看什麼作用它有在下載鏈接，當我選擇了不同的選擇，但那裡沒有運氣，它指向同樣「WLinstaller.exe」。要證明點，我然後下載可執行，无需審閱形式已經它與另一可執行的I比較，它是同樣。如此，如果可執行沒有改變，然後它可能只是網站。

一更神色在HTML和Java語言具體地顯露秘密，曲奇餅。通過點擊「安裝」， Java語言以「包含套全局唯一標識符(的wlxp名義」引起了一個獨特的曲奇餅為我GUID)哪些我現在知道是在我選擇的特殊應用的參考。

document.cookie= " wlxp=p= " +finalList.join (「」) .toLowerCase () + " &t= " +t+ "; expires= " +d;

確定，我甚而跑了處理顯示器在檢查它的文件系統請求的過程。

即使我已經知道關於曲奇餅，它少許仍然衝擊我實際上看它首先詢問我的文件系統發現所有曲奇餅為「live.com」，然後開始訪問那些曲奇餅找到相關信息。 Same applies for Firefox, which I was using at the time. In fact, it’s even more complicated for Firefox because it first has to find my profiles, then shift through megabytes of cookies in the single repository to find the “live.com” one.

Whilst this might seem like a lot of work just to check what I want to install, I think it’s a neat idea with a lot of indirect potential. A few that popped into my mind quickly included:

Third party applications or bundles - assuming the installer simply downloads from the Microsoft server anything matching the supplied GUIDs, you could easily deliver additional applications or service beyond those by Microsoft without bundling them into the installer
Universal installer - this installer will require less if any maintenance since it can be suited to download any application, any version, any bundle by simply changing GUIDs in the browser
Special promotions - imagine if you have accessed a promotional website which offered Live Messenger freebies, by simply adding a code to the cookie, only you will be given access to download these exclusive freebies

Windows Live installer Someone suggested to me this is not new and in fact Adobe may have done this in the past with the Acrobat download bundles, however I think they changed the download URL to a whole new package with or without the bundle depended on your decision, instead of the truly unified installer in this case.

And also if you’re wondering what happens if you don’t have the cookies or have cookies disabled, then you’ll simply be offered a different installation experience where you select which products you’d like to install (left).
