lsass.exe - 3 I/O Reads / Writes per second

[lsass]

The lsass process is doing constant I/O. Process Monitor describes the
action as:

56 1:32:41.6962584
AM lsass.exe 740 RegOpenKey HKLM\SECURITY\Policy SUCCESS Desired Access:
Read/Write
57 1:32:41.6962737
AM lsass.exe 740 RegOpenKey HKLM\SECURITY\Policy\SecDesc SUCCESS Desired

AM lsass.exe 740 RegCloseKey HKLM\SECURITY\Policy\SecDesc SUCCESS
63 1:32:41.6964635 AM lsass.exe 740 RegCloseKey HKLM\SECURITY\Policy SUCCESS

Any ideas what is going on? Note, the old XP trick of disabling Terminal
Services does not have an effect. This is Vista with the latest updates.

Looks like these I/O operations are caused by Task Manager itself. Process
Monitor is quiet when they are not running.
