Created attachment 74631 [details] Make automatic registry save interval configurable
For me it seems to only save if there's changes. I tested by opening regedit and then the system.reg file in notepadqq. I only got notified that the file changed when I changed values in regedit. Of course, it could be that some program you're running makes constant minor registry changes and wineserver needs to flush all these.
Anyways, I added the functionality you want in a patch. Would you mind testing if that works for you?
It's a DWORD called "RegistrySaveInterval" under "HKEY_LOCAL_MACHINE\Software\Wine\Server", representing the number of seconds between automatic saves. 0 means never - flushing at wineserver shutdown is unaffected. This setting does require a wineserver restart though.
Thanks for the patch, I've I've applied it but the server still writes out registry files every 30 seconds despite 0 set as an update interval.
Maybe I created the wrong key?
