In the blog post Why are INI files deprecated in favor of the registry? Raymond Chen enumerates the problems that existed with .INI files that were trying to be solved. He also enumerates the problems the that XML configuration files share with the old .ini files.

The registry has to be in sync with the filesystem. Delete an application without "uninstalling" it and you’re left with stale registry cruft. The filesystem is no longer the statement of record– it has to be kept in sync with the registry somehow.

Introducing Straightforward Advice For Dll

These are the keywords for dealing with the Windows registry. Particular attention is paid to registered applications and their associated file extensions.

Applications that add data to the registry should always work within the framework of predefined keys, so administrative tools can find and use the new data. Views of the registry files are mapped in the computer cache address space. Therefore, regardless of the size of the registry data, it is not charged more than 4 megabytes . There are no longer any explicit limits on the total amount of space that may be consumed by hives in paged pool memory, and in disk space. The size of the system hive is limited only by physical memory. If you own a Windows PC, you’ll be used to performing some basic maintenance tasks to keep it running smoothly and prevent problems with applications or files. Most of us regularly update our virus definitions, empty the Recycle Bin and so on.

Unlike CloseKey(), theFlushKey() method returns only when all the data has been written to the registry. An application should only call FlushKey() if it requires absolute certainty that registry changes are on disk. It was a way to create something new, unfamiliar and taboo to most users, so they would leave it alone. .ini and autoexec.bat files can easily be deleted or changed for the worse. While I can’t comment on other operating systems, the registry also helps maintain the configuration of an application during an upgrade or uninstall/reinstall process. B) Mac OS uses individual files much like the ini files windows used before the registry came along. My crude understanding is the the registry was designed to be a sort of settings repositry, supercerding the .ini files that used to be used.

I understand the need to store truly system-wide settings in one place. Let the operating system store settings however it deems fit. The real problem with the registry is that it was exposed to the outside world. An application must open a key before it can add data to the registry. To open a key, an application must supply a handle to another key in the registry that is already open. The system defines predefined keys that are always open. Predefined keys help an application navigate in the registry and make it possible to develop tools that allow a system administrator to manipulate categories of data.

winreg.HKEY_PERFORMANCE_DATA¶Registry entries subordinate to this key allow you to access performance data. The data is not actually stored in the registry; the registry functions cause the system to collect the data from its source. Long values should be stored as files with the filenames stored in the configuration registry. It is not necessary to call FlushKey() to change a key. Registry changes are flushed to disk by the registry using its lazy flusher. Registry changes are also flushed to disk at system shutdown.
