Just trying to be helpful pre-empting the possible problem and providing an explanation if , unfortunately, not a solution.
Instead of being, inexplicably, irked about this wouldn't providing an alternative pre-emptive solution, if restore points are not available, that the OP could use have been more helpful?
Threads like this with a clear description of the particular trouble in the subject field are likely going to be featured in future search result by countless others. Detailing the possible problems and offering as much information and a range of possible solutions that might be applicable may help others even if some of it turns out not to be relevant to the OP.
