Messed up permissions on Windows 7 -- no programs will start

I tried to fix permissions for a partition, so ended up using an icacls command following suggestions read online. Since it seemed to be taking quite a while, I changed my mind and terminated to process (decided I'll just format the partition).

I don't know if it was this or something else, but another partition -- my Windows partition, to be exact -- now also has messed up permissions. No no programs will start when I boot up my computer.

I read that this could be fixed by running icacls * /t /q /c /reset as an administrator, but that command is giving me a bunch of errors (cannot find path, access denied etc.)
Can this be fixed by using takeown /R /F *? If not, how should I proceed in order to not break up anything more?

Hi, you need patience and should not be playing with permissions unless you know what you are doing, may have to reinstall (you do have backup, right?).

There are a number of ways to go about this, lets try the easiest:-

Log in with your usual user account, open a cmd prompt as admin (as i see you can do).

Open a cmd prompt as administrator, change to the c:\ drive, (I assume this is the OS drive, if not change) for example my prompt is:-

C:\WINDOWS\system32> (what you type is highlighted in red)

At this I type:-

cd c:\ (press enter)

c:\> at this I type:-

c:\>takeown /f c: (press enter), you will receive a message:-

SUCCESS: The file (or folder): "c:\" now owned by user "DESKTOP-F6VLRUA\Paul"

You are back at the c:\> prompt, at this type:-

c:\>Icacls c:\ /grant desktop-f6vlrua\paul:f (Press enter)

(Here you substitute your user name from the proceeding cmd, mine is (DESKTOP-F6VLRUA\Paul) (be patient it is applying permissions and will take some time, you will see the cursor flashing)

After some time a message will appear
processed file: c:\
Successfully processed 1 files; Failed processing 0 files

c:\> type:-exit (press enter) Restart, let us know how you get on.
