win7下无法正常删除exe文件

不知从什么时候开始，我的win7 x64 ultimate就老是这个毛病，删除一个刚刚运行(不知道和运行与否有关)的exe程序，点删除(shift-delete)ok，文件消失了，然而F5刷新一下，这个文件又回来了。反反复复删不掉，放着它不管，那么过几分钟，可能会正常消失掉。这个毛病曾经有一阵子导致我的chrome无法正常升级。我也上网google了好久，中文的网页基本没有结果。今天总算是找到了问题所在，在google英文网页的结果，然后还要多看几个，才找到原因——由于Application Experience这个服务被我禁用导致。把AE服务设置成Manual也行，它会自动启动的。

It's a weird problem - win7 x64 ultimate. When I permanently delete a exe file(such as shift-delete), the file will disappear, but if F5 to refresh the folder, the file reappear. Unless I leave the file a few minutes later. It will be deleted finally. This problem ever prevented me from upgrading my Chrome browser. Now from Google, I find the problem - service "Application Experience" is disabled. I leave this service as manual start. Problem goes away.
