Can’t open or save files after upgrading to Windows 10

I have Thousands of Excel Spread Sheets and Hundreds of Calculators, lengthy Engineering & Building/Structural related Calculations, Workbooks and Drawings effectively negated as a result of the latest MS actions.

The 'Read-Only' function has been supposedly added to aid security ... for whom? Not for the general public, that's for sure.

I can accept the benefits of the 'Read-Only' function where documents are subject to review and in collaboration by numerous entities in Office/Workplace environments but not for the general public at large.

Whilst I believe it is MicroSofts' duty to provide us with functioning software incorporating a degree of security it should not be added carte-blanche without the means of readily circumventing the problems that have arisen.

There has to be a line between providing 'adequate' security as standard, and providing the option to improve security further ... should the Owner which to do so. Most Business Offices have IT specialists specifically employed to perform such tasks!

So ... this is becoming far lengthier than I anticipated, but suffice it to say having tried most, if not all methods purported to fix this problem ... None of them work .... none!

I have made Godzillion modifications along the way, no doubt creating more security holes than the 'Read-only' Fiasco was designed to prevent.

The good news is that modified Excel Documents can be saved, albeit as 97-2003 Work Books with potentially some loss in fidelity ... depends how adept you are in Excel. Bog standard spreadsheets save OK, those with a degree of previously unsupported formatting will still save but functionality will be reduced.

In closing,  MS time to put this problem to bed.

I feel your pain.  Everything will be fixed with Windows 11.  Thats how Microsoft does business.

I truly regret upgrading to windows 10. I cannot open a single file in Office (Word) and was unsuccessful with each of the suggested solutions.

When will this issue be resolved?

Microsoft won't help.  Apple won't help with ios and Google won't help with Android.  Everytime there is an update or upgrade to an operating system there are major problems with bugs.  It doesn't matter if its a computer or a smart phone.  The consumer than has to spend hours on the phone with someone with broken english who is trying to figure out a fix for the problem reading a trouble shooting manual.  It is all very frustrating.

I originally posted my issue as "MAJOR ISSUE EXCELWINDOWS10" on August 2, 2015.  Link shown below:

There has not been a resolution to my posting either (reprinted below).   Eventually I ended up reverting back to Windows 7.

I am just adding my voice to the chorus for Microsoft to fix the problem and ask that I be notified when a "True Fix" is made to Windows 10 resolving the issues with the Office Suite of Programs.

THIS IS A MAJOR WINDOWS 10 AND EXCEL 2007 PROBLEM.

I HAVE JUST UPDATED TWO COMPUTERS. ONE WITH WINDOWS 10 HOME THE OTHER WITH WINDOWS 10 PRO.

I CURRENTLY USE EXCEL 2007 ON A DAILY BASIS. AFTER UPDATING I HAVE FOUND THAT WHEN I HAVE TRIED TO USE AN EXISTING FILE OR WHEN I CREATE A NEW FILE ABOUT THE 2ND OR 3RD TIME I SAVE THE FILE EXCEL 2007 LOCKS UP AND SHOWS "NOT RESPONDING". THIS DOES NOT RESOLVE ITSELF AND AFTER A REASONABLE AMOUNT OF TIME I AM FORCED TO USED THE TASK MANAGER TO END THE TASK.

WHEN EXCEL 2007 ENDS IT LOSES THE CURRENT FILE I AM WORKING WITH AND IT DELETES THE ORIGINAL FILE FROM THE HARD DRIVE LEAVING NO TRACE OF THE FILE.  AUTO RECOVER DOES NOT WORK.

THIS HAPPENS ON BOTH MY COMPUTERS AND WITH EVERY FILE I HAVE TESTED IT WITH, INCLUDING NEWLY CREATED FILES.

ALL SETTINGS SUCH AS AUTO RECOVER ARE APPROPRIATELY SET BUT DO NOT SEEM TO FUNCTION.

I HAVE RUN THE MICROSOFT DIAGNOSTIC TESTS AND THESE TESTS CANNOT FIND ANY PROBLEM

THIS MAKES EXCEL 2007 UNUSABLE AS AN APPLICATION.

HELP!
