I've used system restore in ME a number of times with good success. Any time I install a new program or make major changes, I'll set a checkpoint to facilitate back-out in case of problems. Here is my problem: The documentation states that system checkpoints are taken automatically at boot up and other times. My system once did that, but suddenly stopped. If I want a checkpoint, I have to set it myself.
What has happened? How can I get the system to start taking checkpoints again? I've searched the Windows help system to no avail. Thanks in advance for your help.
