XP Home registry, Shutdown:Clear virutal memory pagefile value

[Don Taylor]

Have a user with XP Home, P4 2.4 Gig, clean system, SP1, pre-SP2.
But shutdown takes minutes, even with no user applications to end.

I searched the registry for "Clear virtual memory pagefile"
and find
Default (value not set)
along with DisplayName, Display Type and ValueType for that.

Is that the equivalent of setting it to 0, so the pagefile won't be cleared?
Or is there some default behavior with no value. If so I'd like to know what
the current behavior is, before I change this to something else.

There are no errors in the logs, there is almost no external hardware attached.

Thank you

Hi Don,

The dword value of 1, clears it.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management]
"ClearPageFileAtShutdown"=dword:00000001

That is right. Unless you actively put in a value there it will not be
cleared. It is not something you should implement to 'improve
performance' - it doesn't. It is for those who have serious security
concerns that someone *might* get at the file when windows was not
running and thus *might* gain access to highly sensitive data retained
in the file

This key needs to have a DWORD value of 0 for a quick shutdown

ClearPageFileAtShutdown

located at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management
