Defragmenter programs can delete System Restore Points

I doubt this is the cause of my issue, but I'll re-boot to Win 7 and see if that deletes Win 8 RP and resets max usage.
I see "Defrag" entries in Win 8 events, but the scheduled defrag did not run at that time.
SOMETHING else did run ...

Could booting in Win 7 add Event entries in Win 8?
I'll test it and let you know.

Thanks.

I re-booted to Win 7 64 and then Win 7 32.
Re-booted to Win 8, and the RP is gone and max usage is reset to 0.
So, that explains what I'm seeing with that.

But, this still doesn't explain what is running to add DEFRAG entries to the Event log, when the scheduled defrag task did not run (as shown in Task History).
And, why are defrags run every few days when they should run once per week ...
But that's really a Win 8 question, not related to this thread topic.
Anyway, for this thread topic - my question is answered - solved.

No, I don't use those type of utilities.
The only cleaner I use is CCleaner.

I did find a Registry key that might have something to do with this:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction

Used Puran Boot time on laptop and desktop PC's here with no loss of Restore Points on laptop, but the desktop had the "Missing" condition on C drive in System Protection which may have happened when it was Startup Repaired in the past without confirming that System Restore points lived on. This is the condition which requires Turning Off in System Protection the "Missing" C listing so that the real C shows up and can be turned On. I've only seen it happen after Startup Repairs recover an OS which then lists in WinRE as "C:\Windows 7 - Recovered."

Are others familar with this and agree it is a Startup Repair byproduct?

Reinstall is really very time consuming option if you have multiple paid programs and games. I was just forced to do fresh reinstall of Windows on my laptop due to HDD crash and just setting Windows the way I want it, took me whole afternoon and some, since everything is wrong on factory setup,(for example why is windows hiding system files from me??) took another 4 hours to reinstall 3.5 GB worth of Win updates and then fun began, looking for keys for all the games and paid programs to install and register them. Some older ones, I can't even find and lost it forever (partially due to moving). Some of my video files don't work due to video and audio codecs not installed, I still have to install printer and scanner drivers and then download another Gig of updates etc. etc. Long story, short it's been 4 weeks and I still don't have my PC 100% restored yet, so I would not do this again on my free will, ever. Granted, I work full time and have wife and 2 little kids so free time is hard to come by, but reinstalling fresh Windows every year or 2 is huge PITA. At least most of the programs I use are portable apps, thank you so much to whoever came out with the concept, otherwise I wouldn't even bother with fresh install, but just reimage old drive from backup. I don't know how other people do fresh reinstall every year, they must be much better organized than me and have plenty of free time on their hands.

Pete, what is this factory install you write about? I thought you said you were doing a clean or fresh install? If you spent all of that time doing the grossly inferior factory install then the time was wasted since it's the worst possible install of Win7 one can have, and one which no tech enthusiast would run.

Did you look at Clean Reinstall - Factory OEM Windows 7?


You only need to do one perfect install then save a backup image which replaces future reinstalls with a 20 minute reimaging operation.

Windows defrag usually runs in the middle of the night so if my machine is always off as far as I know it never runs ?

Defrag should run later if the PC is off at the scheduled time.
You can check when it last ran in Windows Explorer Partition Properties.
If you have Task Scheduler History enabled you can see more info there.
