Pagefile deletion

[Guest]

Hi,

I have a laptop that takes 5 minutes to powerdown when the delte pagefile at
logoff is enabled.
When it is disables it takes a normal amount of time.
Is this a windows issue or a hardware issue?

Thanks

Frank

It takes a long time to overwrite a large file with a bunch of zeros.
Why do you even bother with this? If the information in the pagefile is
that sensitive then I'm sure you must be locking the laptop in a safe
when you don't use it...

Clear Page File At Shutdown

If ClearPageFileAtShutdown is set to 1, shutdown takes a *long* time.

Check this registry key...
Start | Run | Type: regedit | Click OK |
Navigate to...
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Session Manager\Memory Management
Value Name: ClearPageFileAtShutdown
Data Type: REG_DWORD
Value Data: Set to 0
0 = No, do not clear it
1 = Yes, clear it

Read the instructions at the top
248. Right hand side
Clear Page File on Exit - Undo
Click on Undo

clearpageundo.reg is the file that you want. clearpageundo.reg sets the
value to 0.

Clearing the paging file is not a suitable substitute for physical security
of a computer.

I'm with you entirely. I think it hardly ever makes any sense to do this.
Even if there was very sensitive information left in the page file, almost
certainly that same information would reside elsewhere in a saved file on
the drive.
