Windows 10: Revert Permissions to all folders quickly?

Windows 10 seems to have changed the permissions settings to all my files and folders - and I have lot of them (documents, photos, music etc).

I must have at least 30 000 images stored as I'm a pro photographer and thousands of documents. I currently can't save or change anything as I'm told the files are read-only and I don't permission to do that. This is seriously delaying my work.

I'm not on a network and I am the administrator.

Can someone advise me if...

A) There is a universal way to do this throughout my drives (C and D) quickly or if I have to do it by folder (which could take forever).

B) The easiest way to do it.

C) Microsoft are aware of how they have seriously messed up our computers and if they are doing anything about it.

Thanks for any help with this.

:)

 

Read Only Issues - Windows 10 Upgrade

I tried all of this and the permissions revert back to read only. This is a c: folder.

Creating a new folder in Win 10

I have just upgraded to Win 10 from Win 7. Using explorer to look at folders, when I right click, the ability to create a new folder within this existing folder does not appear. I have examined the properties of the existing folder including permissions
and advanced permissions and seem to have allowed for all eventualities to no effect. Still no 'new' option. The folder came up as 'read only' and I changed this too but on re-entry into file explorer it had reverted back to 'read only' again.

 

Right click the C drive or D drive and change the permissions in the security tab

good luck

 

Thanks for the reply, but that didn't work for me . I also tried changing the security settings under the main documents folder. I got an error message saying access was denied.
