Windows 10: Safe to delete Windows.old?

I was purusing my C Drive and noticed Windows.old...just wanted to check if it was safe to delete (imagine upgrade from Slow Ring to Fast Ring 10130 created this)

Thanks!

I'm on the Fast Ring - I ain't got time for old stuff!

Windows 10 Calendar | Remove "Microsoft Account" default calendar

Is there more information about this? I'm having the same issue, and it's driving me nuts(OCD alert)!

Windows 10 Pro x64 Version 1607 (OS Build 14393.693)

Mail and Calendar 17.7812.42257.0

Microsoft People 10.1.3410.0

Store 11610.1001.25.0

Login to Windows using a 'Local Account', not a 'Microsoft Account'.



Two accounts from an unrelated provider. One for e-mail using IMAP+SMPT, another for calendar/contacts using CalDav+CardDav (iCloud). I censored the second account name due to bad language.



And yet, when opening the Calendar. There is an entry for 'Microsoft Account Calendar', wich is unable to be managed.





Things I've tried to fix this:

- Removed and added accounts (Using both 'Calendar-->Manage Accounts' and 'Settings-->Accounts')

- Removed and installed Mail/Calendar/People (Using PowerShell and Store)

- Run Microsoft Troubleshooter for Windows Store

- Run SFC /scannow

- Run DISM /RestoreHealth

- Switched to Microsoft Account, and back to local

- A combination and multiplication of all the above!

So far no fix is noticeable and the problem persist. Where does that 'Microsoft Account' entry comes from? And more important, how to remove it?!

I would really appriciate if Microsoft gave some attention to this issue, and help us solve this.

With kind regards,

Is there more information available to finally solve this issue? An response from Microsoft would be nice.

Hello Bromanbro,

If there's nothing in the Windows.old folder you wanted from the previous installation, then it's safe to delete. *Smile

sometimes it wont delete all. I suppose it depends on your uninstaller. I ended up having to manually delete sub files before I could delete the whole.
