How to Faster Windows Vista Copy File Without Long Calculating Time

I experience poor slow copy file performance over the network in Windows Vista. After i googling, i found that “Remote Differential Compression” may cause of that.

Remote Differential Compression is a Windows feature introduced in Windows Server 2003 and is available on all later versions of Windows. This Windows feature is enabled by default in Windows Vista.

Remote Differential Compression (RDC) allows data to be synchronized with a remote source using compression techniques to minimize the amount of data sent across the network. RDC is different from patching-oriented differencing mechanisms, such as Binary Delta Compression (BDC), that are designed to operate only on known versions of a single file. BDC requires the server to have copies of all versions of the file, and differences between each pair of versions are precomputed so that they can be distributed efficiently from a server to multiple clients.

So to fasten, try follow this steps,

First, turn off “Remote Differential Compression”, go to Control Panel | Turn Windows features on or off, then find and uncheck “Remote Differential Compression”.

Next step, open a command prompt and type,

netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled

Final step, restart computer

Install Form Builder on Vista

i use form builder version Oracle Developer Suite 10g (9.0.4) on XP, then when i install it on Vista, it came with 2 error message, ORA-00604 and ORA-01009.

ORA-00604: error occurred at recursive SQL level string
Cause: An error occurred while processing a recursive SQL statement (a statement applying to internal dictionary tables).
Action: If the situation described in the next error on the stack can be corrected, do so; otherwise contact Oracle Support.

ORA-01009: missing mandatory parameter
Cause: A host language program call did not pass all required parameters.
Action: Check the syntax for the call and enter all required parameters.

This error occured because Vista only compatible with form version & upcoming version 11.1.1.

Then with no other option, i download the new version of Oracle Developer Suite 10g (, it comes with two files (626,122,752 bytes) and (236,880,881 bytes).

When first time i install it, i got problem again. It show this message

“Install has encountered an error while attempting to verify your virtual memory settings. Please verify that the sum of the initial sizes of the paging files is at least 256 MB”

To handle it, click Start | Control Panel | System and Maintenance,

click Tab System, View amount of RAM and processor speed

“uncheck automatically manage paging file size for all drives”

Set Initial size to = 2048 and Max = 4096, then restart your computer.

VB6 on Vista, Error accessing the OLE Registry

When i open VB6 on Vista, i get this message “Automation Error, Error accessing the OLE Registry”.

To avoid this message appears again, i check compatibility to XP and “Run As Administrator”, and now i can work with VB6.


ActiveX component can’t create – DllRegisterServer failed – VB6 – Vista

I’m getting an Error 429 : ActiveX component can’t create object when trying to run a program that ran perfectly fine on Windows XP. It was created in VB6 but does not run on my version of Vista.

So i try to run regsvr32 to register some ocx and dll. But I got error message when i registered some *.dll or *.ocx with regsvr32 in vista,

“The module *.dll was loaded but the call to DllRegisterServer failed with error code 0x800004005”.

The solution is to register the component from just a batch file, right-click and then click “Run as Administrator” fro pop-up menu.
