I have recently built a new machine and loaded it with WIN10 Pro-64. After installing the OS, I started loading lots of programs and utilities. During this process, I made a point of setting Restore Points after every few new installs so if something got whacked, I could limit it down to whatever had been installed since the last Restore Point, roll back, and repeat those installs one at a time, to allow me to identify the offending software. I have only enabled System Protection on the OS drive, and have it set to 10% of the drive which is about 43 Gb (the drive is a Samsung 850 Pro 512 Gb). I set the max Restore Point usage high as I was manually creating a lot of Restore Points.
The other day, I wanted to roll back and discovered that only the 3 most recent Restore Points were there. Yes I clicked the button to show all Restore Points. They are all gone except the last 3. I also noticed in Event Viewer that I was getting the following error anytime I manually set a Restore Point.
Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object.
AddLegacyDriverFiles: Unable to back up image of binary Microsoft Link-Layer Discovery Protocol.
Access is denied.
Event ID 513
I Googled this error and found out it seemed to be related to making back ups, 3rd party backup programs, and Restore Points. The consensus was it is a fairly significant error. So, I have Restore Points disappearing, and I get this error every time I manually set a Restore Point. I have not tried actually restoring one of the 3 points that are still there so I don’t know if the Restore Points are functional or not.
In an attempt to zero in on what is causing this error, I opened up Task Scheduler and opened up the library there to Task Scheduler Library/Microsoft/Windows/System Restore and made a scheduled task to create a Restore Point. I set 1 trigger to perform this task every night at 1:00 am. Then I set another trigger for a 1 time event at another time (9:00 pm). 9:00 pm came and went and as best I can tell, the task did not execute. The repeating one at 1:00 am did not run either. If I select the scheduled task and click RUN, the status changes from Ready to Running, but no Restore Point is made, and it just keeps saying "Running". The Last Run Result column says “The operation completed successfully.” If I go down to the middle section and select the History Tab, it shows various activities – Created Task Process, Task Started, Action Started, Task Completed, but no Restore Point is made. I am attaching a screen shot of the Task Scheduler Window with the Restore Point settings in Control Panel overlaid, and the Event Viewer showing the errors I get when I create a manual Restore Point.
If anyone can help me out, it is most appreciated. My questions are:
1 – Why are my Restore Points disappearing?
2 - Why do I get this error when I manually set a Restore Point?
3 – Why does the scheduled task I have set up to make Restore Points not work?
Great Forum BTW, and Thanks !
