Windows 10: Permissions issue

I have performed a clean install of Win10 on my C drive and it is running fine.

My problem is when I go to install a program from a separate data store disk drive (stored on the drive over the past 5 years when I was running win7) or otherwise open a file from Win10 I frequently get a permission denied/ don't have access error message. I have tried taking ownership but that is not working reliably.

I am not using any kind of drive/file encryption.

Can anyone tell me the best way to resolve this issue as I have a lot of software I want to install on Win10....any help would be much appreciated.

Permissions issue: how to give permissions?

I am seeing the same thing in my event logs, on both a system that was upgraded to windows 10, and on a system that has a fresh install of windows 10.

It happens at start up of windows 10 from what I can tell, and it happens if you setup to use Cortana for searching.

1. When exactly are you getting that error?

Thank you.

 

Welcome to the forum. If it is NTFS and been used by another o/s the rights will be for the user of that o/s taking ownership should work you need to do it to folders not just files have you used our tool to do it Take Ownership Shortcut - Windows 7 Help Forums

 

Ahhh Yes...I forgot I had to use a different user name for my win10 system and that is most likely causing the problem. Could I just add my win7 user name as another user of my win10 system and therefore access the files as I need them without worrying about anything else?

thanks

 

No each account has a sid and even the same name will have a different sid thats what windows sees the sid not the name

 

I would not do that. I would add permissions for your current Win 10 user to the corresponding drive and all of it's subfolders and files. Just changing ownership is not enough, you also need to assign read and probably write permissions. Right click on the corresponding drive (or folder if you don't want to change permissions for the entire drive), select "properties" and there go to the "security" tab. Click on the "Advanced" button and add permissions for your current user. If it's your drive and PC you probably want to grant yourself full control.
