Configure the request of extended file details when opening a file

When opening a file over a network, then besides requesting the file contents, then it also request extended details about the file and the share it resides upon. This gives extra traffic and can increase the time it takes to open a file (Especially if on slow network connections like VPN over DialUp).

One can disable this fetching of extended details by adding the following values to the registry:

REGEDIT4

[HKEY_CLASSES_ROOT\*\shellex\PropertySheetHandlers\{3EA48300-8CF6-101B-84FB-666CCB9BCD32}]
“SuppressionPolicy”=dword:00100000

[HKEY_CLASSES_ROOT\*\shellex\PropertySheetHandlers\{883373C3-BF89-11D1-BE35-080036B11A03}]
“SuppressionPolicy”=dword:00100000

[HKEY_CLASSES_ROOT\*\shellex\PropertySheetHandlers\CryptoSignMenu]
“SuppressionPolicy”=dword:00100000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SCAPI]
“Flags”=dword:00100c02

Note the latest service pack for Win2k(SP4) / WinXP(SP1) has to be applied first before it will recognize these registry entries.
