When do registry changes take effect windows 7

Details required :. Cancel Submit. Shenan Stanley. So the answer to your question depends on the registry setting. No, Windows does not just access the registry at startup of Windows as many settings in the registry are for things other than Windows.

How satisfied are you with this reply? Instead, code should be written to verify redirection status before it makes calls to the bit or bit logical view of the registry. Registry reflection provides a real-time method to hold the bit and bit sections of the registry open at all times. For example, consider a bit program that is named Hello. Registry reflection makes it possible for the Hello. Reflection makes it possible for the existence of two physical copies of the same registry to support simultaneous native and WOW64 operations.

Most of the keys that are reflected are class keys. Class keys are written with a "last writer wins" philosophy, and the handle to the key is closed when either the bit or bit class key is written and closed. Developers can use the RegQueryReflectionKey function to determine the reflection state for a particular key and use the RegDisableReflectionKey function and the RegEnableReflectionKey function to programmatically disable and enable registry reflection for a particular key.

Certain registry subkeys contain constant information that exists in only one copy of the registry even though these keys appear in both the bit and bit registry views.

This is referred to as registry reflection. In current versions of the Windows x64 Edition operating systems, the following registry subkeys are shared across bit and bit program and are not rewritten based on the bit or bit level of the program or process:.

Registry key reflection may change in later operating system versions. Software developers are encouraged to avoid writing program code that is based on previously-documented lists of reflected keys.

Instead, code should be written to verify reflection status before the program makes calls to the bit or bit logical view of the registry. Both bit and bit versions of Registry Editor are included with x64 Edition operating systems.

Hi all, I am creating a Server disk space alert on a windows server R2, and I have added two new rules "DiskSpaceThreshold" and "LowDiskSpaceMinimum" and I am wondering if i will have to reset the server for it to apply the rules since my alert doesn't seem to be working.

See Registry Watcher C If you are attempting to update a registry key for another application or operating system component and want the changes to take effect immediately then this is down to the specific application - be aware that there probably isn't a whole load that you can do unless this is already supported by that application, or you can persuade the application maintainers to modify the application for you.

Instead you should use the defined Windows APIs to do these sorts of things, for example the SystemParametersInfo function can be used to update the wallpaper, see Wallpaper in c : For setting a wallpaper you can use SystemParametersInfo to set a wallpaper image programmaticly.
