I have been struggling with Windows XP Home edition System Restore being disabled from creating System Checkpoints automatically. The error message in the Event Viewer is "The System Restore filter encountered the unexpected error '0xC000000D' while processing the file 'extensions.ini' on the volume 'HarddiskVolume1'. It has stopped monitoring the volume." It appears that either Thunderbird's or Firefox's extensions.ini file in the profiles directory is the cause of this behaviour, and turning off and turning System Restore back on does not restore the creation of these automatic check points. I can however create restore points manually.
I have deleted the files extensions.ini, extensions.cache and extensions.rdf in the profiles directory of both Thunderbird and Firefox and allowed them to be re-created but the problem has not gone away. When the System Restore gets disabled then all of my System Checkpoints are deleted so there is nothing to fall back on if an error should occur and I need to restore an earlier configuation.
Microsoft's has a Hotfix for this particular error message which I downloaded and installed, but it doesn't help and System Restore is still not creating automatic System Checkpoints. I have now resorted to using a visual basic script file run by the task scheduler to create a daily automatic restore point.
I did wonder whether it was the last Thunderbird extension - Thunderbrowse - that I installed that caused the problem, so I uninstalled it. Since then I get System Checkpoints created when installing programs and Microsoft updates but System Restore still fails to create any automatic System Checkpoints apart from the ones that I create through the vbs file. If I re-install Thunderbrowse though, then I get the same Event Viewer "sr" error when a checkpoint is created and all my System Restore points are deleted and I am told that System Restore has been disabled.
Please has anybody got a clue to sorting this one out apart from not using the Thunderbrowse extension for Thunderbird?
