Refreshing a key in HKEY_CURRENT_USER registry hive without restart

[Guest tempnode@gmail.com]

I'm trying to update a registry key (HKEY_CURRENT_USER -> Control

Panel -> Accessibility -> Keyboard Response -> Flags) and refresh the

registry without restarting explorer.exe (or without logging off).

 

I've tried UpdatePerUserSystemParameters from user32.dll, which is

supposed to update HKCU, but it won't work.

 

 

Is there something about this key that won't allow a refresh like the

rest of HKCU?

What do you mean, refresh??

 

If you make a change in the registry and want to refresh, just hit F5 or

click on View in the toolbar and click, refresh.

when i say "refresh" i mean i want the changes to take effect. so, i

change the key, and i want that change to take place in the system.

for example, there is a registry key to enable and disable task

manager. once you enter the key, it takes effect immediately, meaning

that if you make the value 1 and press enter, then try to access the

task manager, it won't work; once you revert it by making the value 0,

you can access the task manager again.

 

that scenario gives an example of what i want to do: make the

registry change to "HKEY_CURRENT_USER -> Control

Panel -> Accessibility -> Keyboard Response -> Flags" and have the

changes take place right away.

Windows loads the contents of many registry keys at boot time or at logon

time. If you subsequently change one of them then the change has no effect

until you log off and on again. The OP wants to know how force Windows to

propagate the change without him having to log off an on.

Some keys you can not do this, you will have Log/off and back on for the

change to take effect.

You can't, you have to logoff/on or stop and start explorer for the change

to take effect. I don't think there is any other way to force the change to

take effect.

Not necessarily. Take NICs, for example. If you manually modify an NIC's IP

address in the registry then the change won't be effective until you reboot

the machine. However, if you do it through the Control Panel then it happens

without a reboot. In other words, if you know the inner workings then you

may be able to propagate a registry change without logging off.

I write VbScripts and I have not found a way to do it yet. Most you have to

logoff/on or do a soft reboot.

Re: Refreshing a key in HKEY_CURRENT_USER registry hive withoutrestart

 

actually Paul,

 

you can update the hive without restarting explorer.exe... and i do

know that some keys require a reboot for the change to take effect.

what determines this?

 

i think this key may be one that absolutely needs a reset, but is

there a way to block keyboard inputs via registry (disabling keyboard)

without rebooting?
