I did something but dont know what
every thumbnail is gone even in the control panel personalize section
1. Looks like you screwed up your registry. Create a new admin account to see if it fixes the problem. Also, try
*4 which is at the end of this post.
2. As to the file integrity checker, it's
cmd -> sfc /scannow (need to have your 7 dvd in drive).
3. There is a third Registry file that is created when Windows is first installed on the computer. If Windows came pre-installed on your system, you will still have this file. This file is in the root directory, so you need to get to that by typing
cd\. This will put you right to the root directory. From there, you need to reset the attributes to the third Registry file by typing
attrib –r –h –s –a system.1st. This file is created when Windows first installs. To use it, type
copy system.1st c:\{windows}\system.dat. By doing this, you copy the contents of
system.1st into a newly created
system.dat file. This new system.dat file effectively resets the main portion of the Registry for you.
Reboot the computer and try it.
* 4. Try these steps:
1) Click on Start and type
regedit at run
2) From left pane find and select the next registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
3) Right click on the right details pane, and create three DWORD (32-bit value) entry (bold only) and set value for each one:
UseMachineCheck – set value: 0.
Blur – set value: 0.
Animations – set value: 0.
4) Close
Regedit
5) Now click Start and type
CMD with administrative Priviliges
6) Next type:
Net Stop uxsms
Net Start uxsms
With this command you will stop already used and start new Desktop Window Manager Session with new options added in registry.
7) Final step is to enable Aero interface with right click on desktop and choose:
Personalize/Windows Colors.
