Security Tip: Clear Page File

Some programs can temporarily store unencrypted passwords and other sensitive information 

in memory. By clearing the Windows paging file (stored in hard disk as Pagefile.sys), we can 

prevent any unsecured data from being contained after the shutdown process is complete. 

This tip will enhance the security but will slow down the shutdown process by another 5 to 8 

seconds.

 If you do not want to compromise on security, follow the tip. 

• Open Control Panel -->Select Administrative Tools--> Choose Local Security Policy--> Local 
  Policies. 
• Now Click on Security Options. 
• In the right hand menu, right click on Shutdown: 
  Clear Virtual Memory Pagefile 
•  Select Enable. 
• Reboot the machine. 

N

ow for the 

guys,

who love to edit the registry for this setting, 

• Navigate to: 
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\
  MemoryManagement. 
• Double click on ClearPageFileAtShutdown 
•  Set Value = 1.
• Click 
  
  
  OK and Reboot.

NOTE :- Take the backup of your registry (by one of these Software's) before doing any tweak.
