Windows 7: configure windows to QUICKLY delete pagefile on shutdown? (not wipe)

configure windows to QUICKLY delete pagefile on shutdown? (not wipe)

so I just discovered what may be one of the dumbest design choices ever if this is true: when configuring windows to clear the pagefile on shutdown (by flipping the ClearPageFileAtShutdown value in registry to 1) windows actually overwrites the entire file (with zeroes probably)
so obviously when that file's several gigs then it takes several minutes to shutdown

anyone found a way to instead tell windows to simply delete it instead? (like users can do by right-clicking delete with the mouse or typing "del pagefile.sys" in command line)



PS. I wanna delete that damn file on shutdown not for security reasons but practicality: so that when backing up with Ghost I don't have to delete it manually (which isn't possible to do in command line outside windows anyway)

also I've read that starting windows without previous pagefile seems to slightly improve performance or something, dunno if that's true

I might be wrong but I would think that Windows empties the Page file on shut down & this is often the reason shut down can be delayed.

A good back up program should not include the Page file as files in the Page file are going to vary all the time, so backing them up would seem futile.

Fiddling with the Page file will probably end up in tears as you really don't know what files are in it.

I very much doubt Microsoft would provide an option to delete the pagefile on shutdown. Raymond Chen, a Microsoft developer since Windows 95 days, would call this a security hole disguised as a feature.

From a security standpoint, which is the entire purpose of the registry setting, deleting the pagefile would serve no real purpose. As is quite well known recovering a deleted file that has not been overwritten is not particularly difficult. For any hacker wishing to access the pagefile this would be a mere speedbump. Overwriting the pagefile is the only way to provide the security the setting was designed to provide. Windows will not allow deleting the pagefile while it is running. That would almost certainly result in a system crash.

Yes, overwriting a large pagefile will take time. That is why it is not enabled by default. In a high security environment this might be a good idea but it makes little sense outside a comprehensive security policy. Most computers have security holes more serious than an uncleared pagefile. The setting has no other benefits.

Most disk imaging software will either provide an option to not copy the pagefile or will not do it at all. Macrium Reflect simply will not copy the pagefile or hibernation file in an image backup.
