There was nothing wrong with it the other day. Today, I cleaned drive C with WIN7 optimizer, made a slimming, and found an installer folder, which clearly stated that it could be safely deleted. It turned out to be really a mud horse pit. After cleaning, the Ofiice icon disappeared. Doc, ppt and other files are file icons that windows can't recognize, but the suffix is correct after checking, and the icons in office such as word and excel in the program group in the start menu can't be recognized. Double-click to open it, even if there is no icon. After online inquiry, I found a solution to the problem. I hope that netizens who encounter similar situations can learn from this example.
Solution: The Office program icon is lost because the Office icon directory in C:\WINDOWS\Installer\ has been deleted, and the files in the folder {90120000-001-0000-000000ff1ce} are in. You just need to copy this folder on other computers with the same version of Office. I take Office 2007 as an example. It is said that the icon of office2003 is in C: \ Windows \ installer \ {9010804-6000-165438-8cfe-0150048383c9. In fact, you can open folders that start with numbers in the installer and find them. If you see an office icon inside, it's him.
