You may want to create a restore point prior to doing this. Here is what I found on the net. Hope it helps you.
Download the .reg file save it to your desktop then right click it and select merge.Now reboot.
This will turn off UAC
open file explorer
right click on C:\
select Properties option
choose security tab
click advanced button
select owner tab
click Edit button
click on the name you want ownership rights changed to ie: your administrator user
tick the box "replace owner on subcontainers and objects"
this should restore your ownership of C:\
hope this helps
Open elevated command prompt and copy and paste the following and reboot.Hit enter after each.
It may take a bit to run.
icacls * /T /Q /C /RESET
You should use:
sc create SysCmd type= own type= interact binPath= C:\Windows\System32\cmd.exe
net start SysCmd
Alternatively you can enable the build administrator account through registry or access system repair through the System Recovery component
1) Reboot your PC
2) On post, keep tapping F8
3) Select System Recovery or whatever the name was
4) Wait until its loaded, you can do system recovery now.
5) If you don't choose system recovery and want to enable the build-in admin, select command prompt
6) Type regedit
7) File (menubar) > Load hive > Select: C:\Windows\System32\config\SAM
8) Go to: <Loaded hive>\SAM\Domains\Account\Users\000001F4
9) Right click and edit the F value
10) Look for a hexadecimal value 11 at row 8
11) Modify it to 10
12) Select loaded hive > File > Unload hive
I want you to create another user account give it admin privelages and see if the issue persist.
Open notepad and copy and paste the below into note pad and name it newprofile.bat
net user new /add /expires:never /passwordreq:no
net localgroup “Administrators” /add new
Save it to your desktop right click run as admin.Then reboot your machine.Then you will have a new account named new do not log into that account just yet.Log into your normal account and then give new admin rights.To do this Hit start>Control Panel>User Accounts>Manage Another Account>Find new>Change Account Type> Standard User should be selected You will need to change the account to Admin >Then Hit the Change Account type button next to cancel.Now reboot into your new account and see if your problem persist.
