I have office 2010 running fairly satisfactory on windows 7. Now my laptop is upgraded to windows 10 and since then office 2010 is not performing properly. Frequently is stops responding. This starts with Excel not responding. I got advise Mr Doug Robbins, Word MVP to make repair from control panel. I did that and it started working however when I downloaded my bank statement in excel format and attempted to open , again excel stopped responding. I tried to repair again but it was not repairing. It was stalled after about 70 % progress for long for almost 12 hours. Then I tried to cancel repair which was also stalled for almost 12 hours. Then I stopped computer and attempted repair. I am successful to get responding excel. But I feel if I open the downloaded file it may stall again. This does not happen when office 2010 on windows 7 system which I rechecked. Please help to resolve this issue on this combination of office 2010 on windows 10.
