Clear pagefile in Win2k

Following up on another tip, member Ron Baron shows how you can plug pagefile security holes without touching the registry.

This is a follow up to the tip, Security breaches, submitted by Tertius Genis. I would like to point out a couple of flaws.

First, the math is bad. With a computer running 250 MB of RAM (how do you get 250MB?) your page file would be 1.5 times the installed RAM. But this would be much closer to 384 MB (based on 256 MB of RAM, which is much easier to buy and install) not 775 MB as stated.

The other major flaw is sending "the average user," or even an administrator, into the registry needlessly is foolish if not career-ending. This is accomplished much more easily through the local security policies.

Local Security Settings
Local Policies
Security Options
Clear virtual memory page file when system shuts down.

This can also be set through the domain policies if you are in that enviroment.

Domain Security Policy
Windows Settings
Security Settings
Local Policies
Security Options
Clear virtual memory page file when system shuts down.
In the "define this policy" box, check enable.

Easy... and nobody has to put an incorrect entry in the registry and bugger the system.

You can also set this through the domain policies in Active Directory users and computers.
