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:

  1. Stopped all unnecessary services/background programs.
  2. No COM add-ins are active in Excel.
  3. 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?

  • My Excel 2010 32bit (Win 7 Pro) sometimes breaks down completely, if I have too many (overlapping) conditional formats. This can happen after frequent move, cut/copy (paste) operations. After cleaning up the conditional formattings, I can edit the cells again. – fheub Jun 24 '15 at 8:16
  • @fheub: I do not need to do anything special to reproduce the above. Opening a default blank workbook and trying to type 1 in the first cell (A1) can produce this for me. – dotNET Jun 24 '15 at 9:27
  • I can do the following interesting sequence too: Start Excel, Type "a" in A1 ("a" appears without hanging), press ESC, type "a" again (gets stuck for 5-6 seconds, then "a" appears), press ESC, type "a" again ("a" appears without hanging) and so on. – dotNET Jun 24 '15 at 9:33

have you tried disabling automatic formula calculation? (formulas ribbon, far right)

If this works, then it's probably that your workbook just has a lot of intense formulas to calculate (array formulas, or lookups referencing a whole column for example)

  • Thanks, but this is not the case. I can produce this behavior on empty workbooks too. – dotNET Jun 24 '15 at 9:35
  • what conditions produce this? – Some_Guy Jun 24 '15 at 10:21
  • Very odd for things to happen on blank workbooks... have you done anything funny with your personal.xlsb file? this can hold macros and things which could be running in the background when certain things happen. Otherwise I'd also double-check there's nothing outside of excel trying to hijack any functionality (such as malware or a keylogger, if you've got nothing legit which would do such a thing) – Steve Taylor Jun 24 '15 at 11:09
