Vista Permissions (Replacing corrupt .DLL)

My computer had been playing up recently. So i figured i’d run a little check disk to make sure everythings in order. It seemed that not alot was in order as it needed delete corrupt files etc. Anyway. When i got back on windows i had an error come up that mshtml.dll was corrupt. When checking it in System 32 directory it appeared that the file was empty. nothing in it? a quick check online says it usually is around 2.5mb in size. So i downloaded a replacement i found online.

Start to copy this file over with the usual security check whether you’re sure you want to do it and i get shown an error: ““you need permission to perform this action” Wait.. i thought i just gave permission by clicking continue?! Anyway. i checked online and came across a 5 min solution:

1. Right-click the file and select Properties.
2. Click on the Security tab.
3. Click Advanced in the lower right.
4. In the Advanced Security Settings window that pops up, click on the Owner tab.
5. Click Edit.
6. Click Other users or groups.
7. Click Advanced in the lower left corner.
8. Click Find Now.
9. Scroll through the results and double-click on your current user account.
10. Click OK to all of the remaining windows except the first Properties window.
11. Select your user account from the list up top and click Edit.
12. Select your user account from the list up top again and then in the pane below, check Full control under Allow, or as much control as you need.
13. You’ll get a security warning, click Yes.
14. On some files that are essential to Windows, you’ll get a “Unable to save permission changes… access is denied” warning and there’s nothing that you can do about it to the best of my knowledge.
15. Reconsider why you’re using Windows.

I just got that from:

Thought i’d post this incase i need a quick reference again in future.
