Why is system restore disabled by default?

But back to your original question( a good one at that) I guess that maybe during install(when winsat is first run maybe) it checks if there is enough disk space or good enough CPU for VSS, as smaller devices such as phones and tablets don't.

I've found System Restore is mostly switched off after installation. Disk space is a good theory, as I'm often installing on a VM, and my old physical hardware has a small C: partition.

Any ideas? I understand, that 10 relies on reset/refresh, but disabling SR is a bit drastic.
Especially taking into account, how many flaws are in 10 right now, I wonder how it made RTM.

Answer : windows 10 system restore disabled with 128 gb hdd.
upgrade to 256 or more, will work fine.

Strange. SR was disabled on 2 fresh installs for me. Wonder if it has to do with drives being SSD.

It was disabled for me after upgrading from W7 Ultimate to W10 Pro. No clean install just upgraded through Windows Update. It was on and configured to my specs in W7 when I did the upgrade, but I had to manually reconfigure it in W10. I have more than enough space on my drive (183GB free).

To turn on System Restore, hit Windows button and Pause/Break key. In System Properties, highlight your "C" drive and click "Configure". This now allows you to turn on System Restore. Size or type of drive doesn't matter. Took me 2 days to figure out I had to highlight the "C" drive.

After upgrade to W10 a lot of setting were not carried over but it seemed to work ok. I found system restore was switched off so switched it back on. Seemed like a big mistake as system became unstable, after this errors in file system kept creeping in (file location \\?\volume\xxxxxxxx) on any new file created. Tried various repair options non worked and system became so unstable I was forced to revert to W7. Unfortunately the same file save errors kept occurring. I am now running disk check and it seems like it is repairing all the files on my data drives. I have upgraded five computers to date and all have worked flawlessly without system restore switched on. The only problem machine is the one that I switched system restore on. Maybe small (128GB SSD) system drive or raid 10 array for data drives issue, as these are the only major differences between the different systems. Anyway I will see what the disk repair turns up and reinstall W10 and run it without system restore and see what happens. There maybe issues that do not yet have a universal answer and MS used the failsafe of switching system restore off, interesting to find out eventually.

Yep 128GB SSD was disabled for me also, it stopped me reading disk images until I turned it back on after deleting the windows old folder.

SR was on by default on my clean install.

Seems a mixed bag. I have seen more than one instance of it being set off.
