窗口清洁 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的机器越来越慢日复一日，那么你可能想象，清理你的Windows “预取”文件夹将加快不知您的机器。

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.这是一个神话，一直在做的子弹在互联网上了好几年，加上其他一些有参考如下。

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.在预读系统是添加到Windows以提高操作系统的性能，节约基本摘录有关最近使用的程序，并允许他们被载入更快下次你需要他们。 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.在短期内它运作良好，并有证据表明，删除您的预取文件夹将放慢改革的步伐，以及导致不再启动时间。

Microsoft MCSA, Larry Miller gave me the full skinny, with references.微软MCSA ，米勒给了我充分消瘦，与参考。 Deleting disabling prefetch is a “BAD IDEA”, he told me, it will impair performance.”删除禁用预取是一个“糟糕的主意” ，他告诉我，它将损害的表现。 “

Prefetch files are used to optimize both boot and applicaton launch times. 预读文件用于优化既引导和应用发射的时间。 Application prefetch files are referenced only after application launch has been initiated. 应用预取文件只能参照申请后发射已经开始。 Unused or rarely used entries will have virtually no impact on performance. 未使用或很少使用的条目将几乎没有影响性能。 Manual deletion of these files will impair performance and has no benefits. 手动删除这些文件会损害性能，并没有任何好处。 In any event the folder is self cleaning after 128 entries. 在任何情况下该文件夹的自我清洁后， 128个条目。 All of this has been extensively tested. 所有这一切都得到了广泛的测试。

He adds that for proper prefetch operation it is essential that the Task Scheduler service be enabled and set to Automatic.他补充说，适当的预取操作是至关重要的Task Scheduler服务启用并设置为自动。 If it is not prefetch will be crippled, leading, once again, to impaired performance.如果不是预取将陷于瘫痪，导致再次受损的表现。 “Prefetch works well in the short term and long term,” says Miller, “No user action is needed or desirerable. “预行之有效的短期和长期， ”米勒说， “没有用户的需要采取行动或desirerable 。 Anyone who suggests otherwise has no understanding of how prefetch works.”任何建议否则谁没有了解如何预取工程。 “

My machine is getting really slow and it’s been irritating.我的机器变得非常慢，这是刺激。 I checked this folder and there are only 4mb, it seems too little amount of files to delete.我检查这个文件夹，只有4MB的，它似乎过于少量的文件删除。 What do you say?你说什么？

Couple of additional things to check: remaining hard disk space.夫妇更多的东西来检查：剩下的硬盘空间。 If that’s low it can slow your machine, also hard disk fragmentation levels.如果是低它可以减缓你的机器，也很难磁盘碎片的水平。 And, spyware/malware if you’ve got any serious malware it could slow the fastest machine to a grinding halt.此外，间谍软件/恶意软件如果您有任何严重的恶意软件它可以缓慢速度最快的机器的研磨停止。
