Some programs on start menu showing the "unknown" icon

EDIT: Solution found! (Post 3)

For some reason, Adobe Acrobat Pro, PowerPoint, and QuickTime all have the default Windows "unknown" icon next to them on my Start Menu (and also on the taskbar if I open the program.) I thought I might be able to right click -> Properties -> "Change Icon" but it is greyed out and I can't even click on the "Change Icon" button.

Anyone know how I can fix this?

 

That's interesting. It made me go look at mine and they are all fine. Hopefully someone has the answer because my husband said he noticed the same thing on some of his.

• Delete the file IconCache.db in C:\Users\yourname\AppData\Local
  
• Create a new empty file named IconCache.db in the same folder. This can be done, for example, by opening Notepad and doing nothing but going to save, entering the aforementioned file name exactly as written, and clicking save.
  
• Right click the file you have just created and make it Read Only. Vital step!!
  
• Reboot the computer. All your icons are recreated correctly.
  
• Go to the IconCache.db file you created and uncheck the Read Only box.

 

Doesnt deleting the icon cache then reboot just solve it :| ?

 

I'll have him take a look at your answer when he gets home. Thanks for posting back.

 

Yes, that should be sufficient.

 

I don't understand the point of creating the new one and then marking it read only. Seems like wasted steps.
