Can't Maintain Specific Desktop Icon Setting?

System: Windows 7 Ultimate x86, Version 6.1 (Build 7601: Service Pack 1)What I'm looking for:I'm asking if anyone knows the precise location to the setting for the Desktop View icon size setting, either a settings file or registry location (NOTHING ELSE). This is viewable by: Right-clicking the desktop -> Selecting View -> Large Icons, Medium Icons, or Classic Icons Problem,Every time I set the option to Classic Icons, it resets to Medium Icons after rebooting.I'm NOT looking for any of the many ways to change this setting through means of:

1) Personalize -> Window Color -> Advanced Appearance settings -> Icon Size

2) Theme settings

3) Group Policy settings

4) Ease of Access -> Change Administrative Settings -> Apply all settings to the logon desktop (Remains unchecked)

5) Ctrl + Mouse-Wheel method of changing icon size

6) Rebuilding Icon Cache

7) HKEY_CURRENT_USERControl PanelDesktopWindowMetricsShell Icon Size

8) HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionThemesThemeChangesDesktopIconsTo reiterate

This is NOT a problem with setting the icon size or themes.Minimum icon size is 16, which on Medium is larger then Classic at 32 (default). It's NOT a problem with any 3rd party programs or services.I've tested with a selective startup disabling all non-Microsoft services and startup programs. Neither is it a malware or virus issue.I've explored this to no end. I've tried "sfc /scannow" to locate any altered/corrupt/missing system files as well, all are accounted for and working properly.I need to locate the exact location for this particular setting (View: Large/Medium/Classic) and find out why it will not save appropriately. I've been to so many forums with so many different fixes and none of them work. I believe I've covered all methods I've attempted but I might have missed one. I rarely have need to ask on forums, but I've exhausted my search abilities to no avail.
