Windows Vista can run out of memory while copying files

These don’t have to be large files and the problem can also occur when copying smaller groups of files that in total exceed 16,400 files between reboots. Following the “Out of Memory” message a range of other errors can occur such as menus and tabs disappearing within the Windows environment and even reboots and BSODs are reported.

Although the problem occurs where users are running Kaspersky security products, it’s a kernel leak that lies at the root of problem (the problem’s not confined to systems running Kaspersky software, that just that this application seems to exacerbate the issue).
