Windows 7: Control Panel - Change Default Icon

I just used OPTION TWO with your icon saved at the same location, and it's working fine for me after logging off and on.

Use step 2 in OPTION TWO to reset everything back to default, log off and on, and try OPTION TWO again double checking for any small possible mistake being made to see how it goes this time.

Yes! It worked this time. Perhaps something crashed when I logged out. For some reason my computer crashes when i log out. Thanks though!

I'm happy to here that your Control Panel icon is changed to how you wanted now.

If you like, please create a new thread with any related details you can think of about your computer crashing when you log out, and we'll be happy to see what we may be able to do to help. It wouldn't hurt to see the link below, and include the report with the post to hopefully help with finding the cause.

It turns out that I only had a log off problem during the process of changing my icon. Now I can log off without the computer freezing.

First of all, really thanks for this tutorial.
I have just 2 problems with my custom control panel icon: first in the taskbar...there the icon showed is the default...i tried to change even the System.AppUserModel.RelaunchIconResource but without success.
The second problem is in the control panel; there in the address bar(or omnibox-i don't know the right name) the icon showed is my custom one with the category view but when i switch in the icons view(big and small) it return the default one.

Anyone can halp me?

Hello Eosim, and welcome to Seven Forums.

See if doing both OPTION ONE and OPTION TWO may sort this for you. Be sure to set the icon at all registry locations.

Hope this helps for now,

Thank you for your answer, Brink.
Yesterday i changed all the default icon keys find in this tutorial, the 2 under CLSD and the other 2 under explorer and that was the outcome
Today i have change directly the icon in the imageres.dll (27) and the control.exe icon...but still have the dafault one in taskbar and in the address bar of control panel in the icons view (big and small)...maybe there is other files with that default control panel icon?
between sorry for my bad english

now is perfect...i just follow your guide Icon Cache - Rebuild and it work...before i just delete the iconchace manually under appdata\local...
Really thanks

Hi Brink,

I was having some frustration trying to get the Control Panel icon to change. As it turns out, you have to replace the original path with your new icon in additional places in the registry, especially if you have a 64-bit Windows. I just found this out a few minutes ago by searching for imageres.dll,-27 throughout the registry and replacing it with my new icon.

I'm posting a list of places where Control Panel looks for its icons, which I found need to be updated to reflect the path of your icon. Turns out there are quite a few of them, if you're changing the value for all users (a dozen for 32-bit, plus 10 additional for 64-bit, makes 22 in total!), which makes me wonder if a find-and-replace program for the registry would be most helpful for this task.

Keys that I did not find in the original tutorial are highlighted in bold green. The full list is as follows:

32-bit all-users keys in HKEY_CLASSES_ROOT:
  • HKEY_CLASSES_ROOT\CLSID\{21EC2020-3AEA-1069-A2DD-08002B30309D}\DefaultIcon (is mentioned at this link)
  • HKEY_CLASSES_ROOT\CLSID\{26EE0668-A00A-44D7-9371-BEB064C98683}\DefaultIcon
  • HKEY_CLASSES_ROOT\CLSID\{328B0346-7EAF-4BBE-A479-7CB88A095F5B}\DefaultIcon
  • HKEY_CLASSES_ROOT\CLSID\{5399E694-6CE5-4D6C-8FCE-1D8870FDCBA0}\DefaultIcon
  • HKEY_CLASSES_ROOT\CLSID\{ED7BA470-8E54-465E-825C-99712043E01C}\DefaultIcon
64-bit all-users keys in HKEY_CLASSES_ROOT:
  • HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{21EC2020-3AEA-1069-A2DD-08002B30309D}\DefaultIcon
  • HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{26EE0668-A00A-44D7-9371-BEB064C98683}\DefaultIcon
  • HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{328B0346-7EAF-4BBE-A479-7CB88A095F5B}\DefaultIcon
  • HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{5399E694-6CE5-4D6C-8FCE-1D8870FDCBA0}\DefaultIcon
  • HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{ED7BA470-8E54-465E-825C-99712043E01C}\DefaultIcon
32-bit all-users keys in HKEY_LOCAL_MACHINE:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{21EC2020-3AEA-1069-A2DD-08002B30309D}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{26EE0668-A00A-44D7-9371-BEB064C98683}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{328B0346-7EAF-4BBE-A479-7CB88A095F5B}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{5399E694-6CE5-4D6C-8FCE-1D8870FDCBA0}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{ED7BA470-8E54-465E-825C-99712043E01C}\DefaultIcon
64-bit all-users keys in HKEY_LOCAL_MACHINE:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{21EC2020-3AEA-1069-A2DD-08002B30309D}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{26EE0668-A00A-44D7-9371-BEB064C98683}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{328B0346-7EAF-4BBE-A479-7CB88A095F5B}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{5399E694-6CE5-4D6C-8FCE-1D8870FDCBA0}\DefaultIcon
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{ED7BA470-8E54-465E-825C-99712043E01C}\DefaultIcon
32-bit and 64-bit per-user keys in HKEY_CURRENT_USER (note there is no 64-bit per-user key by itself):
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{26EE0668-A00A-44D7-9371-BEB064C98683}\DefaultIcon
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{5399E694-6CE5-4D6C-8FCE-1D8870FDCBA0}\DefaultIcon
It is not necessary (and as I discovered, not possible) to change the value in the string:


which can be found under the keys



HKEY_CLASSES_ROOT\CLSID\{26EE0668-A00A-44D7-9371-BEB064C98683} (if on a 64-bit system).

Changing the string values in the rest of the keys works fine. At least it did for me, and I have proof:

Yes, Virginia, that is on a Windows 7 system!

Thanks to you, Brink, for the original tutorial. I couldn't have come this far without you.
