Microsoft Office 2010 icons missing in Windows 7

Since yesterday, I found the icons of Office 2010 files like Excel, Word, PPT's got replaced by the generic file icons.

I looked throughout the web for a solution but nothing worked. The primary solutions put forward were:

1. Delete the IconCache.db file in %userprofile%\AppData\Local
2. Create a registry key "Max Cached Icons" in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer and set it to 4096 (4MB) or 8192 (8MB)

Folks talked about fixing the "C:\Windows\Installer\" but the solution was not complete. So the steps are:

1. Open Registry Editor : regedit.exe
2. I have taken the example of Excel icons missing. So Navigate to HKCR\AppId\EXCEL.EXE
3. Look for the value for "Appid". For me the value was "{00020812-0000-0000-C000-000000000046}"  - this may be different for you. So note it down.
4. No look for the value HKCR\CLSID\{00020812-0000-0000-C000-000000000046}\DefaultIcon (Change the Appid value to what you noted above).
5. Find the value for "Default". For me it is : "C:\Windows\Installer\{90140000-0011-0000-0000-0000000FF1CE}\xlicons.exe,3"
6. Now look for this location "C:\Windows\Installer\{90140000-0011-0000-0000-0000000FF1CE}\xlicons.exe" in your drive. If you already have it then it is a different issue for you and look for other solutions in this thread. If you do not have this folder, copy it from some other desktop and it should work.

Good luck :-)
