Speeding up Windows Vista file copying by disabling one feature

As many know (especially Microsoft), Windows Vista has it’s share of detractors.  One of the biggest complaints has been how this new operating system succeeded in slowing down even the most powerful of computers systems.   One of the many day to day functions any computer system will is is copying and moving of files.

One of the “features” that Microsoft built into Vista to help performance is going to hurt it for many home PC users.  This is called Windows Remote Differential Compression.  It was made in order to constantly monitor files over a network and use a type of compression to minimize the amount of data sent so that large files moves wouldn’t be so costly in terms of bandwidth.  This does, in fact, make sense in a networked environment.  However, this will cause problems with home users with a single computer for very little intra-computer transfers.

In the home user world, this is a case where the cpu cost far outweighs the bandwidth cost.   In a corporate or wide area network environment, the opposite is true.  This is another feature Microsoft decided to leave on by default.

The best bet for home users is to disable this feature.  More bandwidth may be used during these infrequent times but overall, system performance won’t be degraded by nearly as much.  Here’s how we do this:

1. Click the Start button
2. Select Control Panel
3. Click Classic View on the left side of the window
4. Double-click on Programs and Features
5. Click Turn Windows Features On And Off on the left side of the window
6. Uncheck Remote Differential Compression
7. Click OK.
