First Major Update for Windows 10 Available

I now have a 500 MB system reserved partition on my drive after a clean install. I think it was 450 MB previously. Its a required system partition. Delete it and you likely won't be able to boot into windows.

And it's needed for something? Because I can't delete it :/

Why would you want to delete it?

Just leave it as it is and forget about it.

+1.. Mine also went from 450Mb to 500Mb.

No recovery partition either? It's gone after doing a clean install? There was always one in the past, even on a clean install on a blank drive.

Well, just what says Doogie:



It is, indeed. It reminds me a lot to what some manufacturers do to create a recovery partition when you buy a laptop, for example. Is not a bad thing and, moreover, 500Mb is nothing nowadays in terms of disk space. So, I'm fine with it if it can make aesier the recovery process in case I need it, but I think Microsoft should explain it themselves. Should have been informed.

Windows 7, 8, and 10 all create that hidden system partition. The size depends on which OS creates it. There are usually a few others too. If you have a UEFI BIOS there is usually a hidden EFI partition in Windows 8 and 10. If you install in UEFI mode that is.

A UEFI clean install creates 4 partitions, 1 of which does not show up in Disk Management. The 3 that do are Recovery Partition, EFI System Partition, and C: drive.

No recovery partition here. Also the 128 MB partition that only shows up in diskpart is missing? This PC doesn't have a UEFI BIOS so no EFI partition..
