Don’t Clean Your Windows不要清潔您的Windows

窗口清潔 If you’re Windows XP machine is getting slower day by day, then you might imagine that clearing out your Windows “Prefetch” folder would somehow speed up your machine.如果你是Windows XP的機器越來越慢日復一日，那麼你可能想像，清理你的Windows “預取”文件夾將加快不知您的機器。

This is a myth that has been doing the rounds on the internet for several years now, along with several others which are referenced below.這是一個神話，一直在做的子彈在互聯網上了好幾年，加上其他一些有參考如下。

The Prefetch system was added to Windows to improve the operating system’s performance, by saving essential snippets of information about recently used programs and allowing them to be loaded more quickly next time you need them.在預讀系統是添加到Windows以提高操作系統的性能，節約基本摘錄有關最近使用的程序，並允許他們被載入更快下次你需要他們。 In the short term it works well and there is evidence that deleting your pre-fetch folder will slow things down as well as lead to longer boot times.在短期內它運作良好，並有證據表明，刪除您的預取文件夾將放慢改革的步伐，以及導致不再啟動時間。

Microsoft MCSA, Larry Miller gave me the full skinny, with references.微軟MCSA ，米勒給了我充分消瘦，與參考。 Deleting disabling prefetch is a “BAD IDEA”, he told me, it will impair performance.”刪除禁用預取是一個“糟糕的主意” ，他告訴我，它將損害的表現。 “

Prefetch files are used to optimize both boot and applicaton launch times. 預讀文件用於優化既引導和應用發射的時間。 Application prefetch files are referenced only after application launch has been initiated. 應用預取文件只能參照申請後發射已經開始。 Unused or rarely used entries will have virtually no impact on performance. 未使用或很少使用的條目將幾乎沒有影響性能。 Manual deletion of these files will impair performance and has no benefits. 手動刪除這些文件會損害性能，並沒有任何好處。 In any event the folder is self cleaning after 128 entries. 在任何情況下該文件夾的自我清潔後， 128個條目。 All of this has been extensively tested. 所有這一切都得到了廣泛的測試。

He adds that for proper prefetch operation it is essential that the Task Scheduler service be enabled and set to Automatic.他補充說，適當的預取操作是至關重要的Task Scheduler服務啟用並設置為自動。 If it is not prefetch will be crippled, leading, once again, to impaired performance.如果不是預取將陷於癱瘓，導致再次受損的表現。 “Prefetch works well in the short term and long term,” says Miller, “No user action is needed or desirerable. “預行之有效的短期和長期， ”米勒說， “沒有用戶的需要採取行動或desirerable 。 Anyone who suggests otherwise has no understanding of how prefetch works.”任何建議否則誰沒有了解如何預取工程。 “

My machine is getting really slow and it’s been irritating.我的機器變得非常慢，這是刺激。 I checked this folder and there are only 4mb, it seems too little amount of files to delete.我檢查這個文件夾，只有4MB的，它似乎過於少量的文件刪除。 What do you say?你說什麼？

Couple of additional things to check: remaining hard disk space.夫婦更多的東西來檢查：剩下的硬盤空間。 If that’s low it can slow your machine, also hard disk fragmentation levels.如果是低它可以減緩你的機器，也很難磁盤碎片的水平。 And, spyware/malware if you’ve got any serious malware it could slow the fastest machine to a grinding halt.此外，間諜軟件/惡意軟件如果您有任何嚴重的惡意軟件它可以緩慢速度最快的機器的研磨停止。
