This is Excel 2013 (32-bit) on Windows 7 Ultimate (64-bit). The problem I'm facing is that Excel often (but not always) gets stuck when I start typing in a cell. The freeze continues for maybe 5 or 6 seconds (and is system-wide) and Excel would then resume normally. I have checked the following:
- Stopped all unnecessary services/background programs.
- No COM add-ins are active in Excel.
- I used procmon.exe to see what causes the freeze. Here are the relevant lines:
1:07:25.3513382 RegQueryKey HKLM BUFFER TOO SMALL Query: Name, Length: 0
1:07:25.3513532 RegQueryKey HKLM SUCCESS Query: Name
1:07:25.3513940 RegQueryKey HKLM\SOFTWARE\Microsoft\Office\15.0\ClickToRun SUCCESS Query: HandleTags, HandleTags: 0x100
1:07:25.3514113 RegOpenKey HKLM\SOFTWARE\Microsoft\Office\15.0\ClickToRun\REGISTRY\MACHINE\SOFTWARE\Wow6432Node\Microsoft\CTF\KnownClasses NAME NOT FOUND Desired Access: Maximum Allowed
1:07:25.3514334 RegOpenKey HKLM\SOFTWARE\Wow6432Node\Microsoft\CTF\KnownClasses NAME NOT FOUND Desired Access: Maximum Allowed
The next entry in procmon has timestamp set to 1:07:31 (6 seconds), during which the entire system remains unresponsive. Does this give anyone any clue as to what is going on?
