اطلاعاتی که در paging file قرار دارن ممکنه محافظت نشده باشن . پس برای اینکه قبل از خاموش کردن رایانه اطلاعات paging file به صورت خودکار حذف بشن باید از طریق رجیستری عمل کنید :
رجیستری ادیتور رو اجرا کنید ( Run>regedit)
کلید ClearPageFileAtShutdown رو در این مسیر پیدا کنید :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management
و مقدارش رو برابر با 1 قرار بدین .
اگه چنین کلیدی وجود نداشت خودتون بسازید :
Value Name: ClearPageFileAtShutdown
Value Type: REG_DWORD
نکته : زمان خاموش شدن ویندوز به دلیل اینکه در حال پاکسازی paging file کمی بیشتر از حالت عادیه .
Paging File
The Windows paging file is a temporary area of storage on your computer's hard drive. Although the hard disk in your computer is usually too slow to be used for data that the computer is currently working on, Windows can use the hard drive to store paging files, which contain data that is quickly swapped out of memory to make room for new information. If you ever noticed a pause, followed by a burst of disk activity when you switched from one program to another, this could have been caused by Windows using your paging file, to store or retrieve data from your hard drive into main memory.
Because Windows can potentially store any information in these files, they represent a security risk. Although the risk is fairly minimal and the effort required to search through a Windows paging file is considerable, nevertheless the risk does exist. Some security experts recommend disabling Windows paging files altogether. However, on systems with limited memory this is not practical. If you need to use paging files and you are concerned about security, you can set Windows to clear your paging files every time you reboot.
