Windows User Folder Permissions (Dual Boot)

So I finally had enough reasons to upgrade to a Win8 platform yesterday (new SSD boot disk, better leap motion device support) though I'm running into a problem I can't remember for the life of me how to fix.

in my Win 7 install (separate regular HDD, old boot drive) a good chunk of the files I use every day are in the user subfolder, which is permissions-locked to that user account.

When I try to access it in windows 8 and then try to force access (as admin) it attempts to access but never succeeds.

Is there a way to allow the Win 8 install to access that user folder without breaking it for the existing win 7 install? (still need the boot functionality for a few legacy programs)

Not used to being on the "needing help" end of things, but if anyone has the answer I figure it would be here.

 

Go in Windows 7 and remove the specif permission you set and leave at default.

Default permissions are:
-> SYSTEM (full access)
-> <ACCOUNT NAME> (full access)
-> Administrators (full access)
-> Owner of the file should be the account.

If your files are encrypted by Windows (file name will be in green), then you need to export the certification of the encryption of Windows, and import it in Windows 8.

If the above doesn't concern you, then check here:

Click on: I installed a new version of Windows and now I can't open a folder.

 

So, things get slightly more interesting, since the username on the windows 8 install does NOT match the current username on my windows 7 install (using the new microsoft account login because of the surface pro I was gifted)

my goal is to allow the win 8 install access without breaking the permissions under win 7, and I'm fairly certain the "replace owner" permissions hijack done by the link you posted would render win 7 unusable (you can understand if I am hesitant to try it)

the attached image shows the current state of my Win7 user folder.

 

Been a while since I done this, but remember something about taking ownership of the files. You can go into advanced on the permissions window, click change permissions, and then assign permissions to whomever you want. System, and yourself and some other default accounts are a good idea.

Look at Goodbytes reply also regarding encryption.

EDIT: Pretty sure you have to do all this from Win 8 side, and not Win 7 side. Win 7 doesn't know about your Win 8, so a user created, even if it matched, means nothing since that is not how permissions are handled. Names are mostly for your personal reading pleasures Go into Win 8 and add yourself some permissions. Might get blocked, but I remember there is a way, and it wasn't very complicated.

Worst case you can use built in PowerShell in Windows 8 to manual create your own permissions and tell Win protection to go **** itself Oo

 

I have said invalid information. I have just tested what I said.
Account name and password does not need to match. I recalled incorrectly.
Each account has ID (called an SID), this is how permission of files don't screw up if you rename the account name.

If you are scared about Microsoft instruction, how about testing it on a single file? Go in Win7, make a test file, and go back to Win8 and test it.

 

Personally, I would just boot up Windows 8 and run the following command from an elevated command prompt.

Code:

icacls [i]path to folder[/i] /grant Everyone:f /t

Then it won't screw the Win 7 install and it won't matter what your username is, you'll have access.

Alternatively, if you only want your user to have access then run:

Code:

net user

That will list your actual username (probably something_000). Then run:

Code:

icacls [i]path to folder[/i] /grant someone_000:f /t

Edit: Please be aware that it can take a long time for the commands to complete if your user folder is large.
