Windows 10: my excel files corrupt after forced windows update

Hi,


As usually, I left my programs open and PC on overnight, and Windows possibly made an update and restart. This corrupted my Excel bookkeeping file I've run for 25 years. So far, I've found no way to fix it. The 170 mb file with tens of sheets and hundreds of thousands of rows, heavy formatting and complicated formulae contains all the information about my financial and work activities from the last 25 years. This must have happened because Windows, upon restart, didn't wait enough for the Excel to have time to save my files and shut down in halfway of save process. No need to say that it equals a serious robbery to me, or worse.


My question is as follows: Is there a way to stop windows from spontaneous restarting on update OR increase delay time upon restart, so my programs have time to save files?

:)

 

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.

Microsoft Windows Home Server Corrupts Files

Microsoft has warned Windows Home Server users not to edit files stored on their backup systems with several of its programs, including Vista Photo Gallery and Office's OneNote and Outlook, as well as files generated by popular finance software such as Quicken and QuickBooks. "When you use certain programs to edit files on a home computer that uses Windows Home Server, the files may become corrupted when you save them to the home server," Microsoft said in a support document posted last week. The document went on to list the software, which includes Windows Vista Photo Gallery, Windows Live Photo Gallery, OneNote 2003, OneNote 2007, Outlook 2007, Microsoft Money 2007 and SyncToy 2.0 Beta. Others programs, however, may also corrupt files stored on a home server powered by Microsoft's operating system. "Additionally, there have been customer reports of issues with Torrent applications, with Intuit Quicken and with QuickBooks program files," the document said. "Until an update for Windows Home Server is available, we recommend that [you] do not use the programs that are listed to save or to edit program-specific files that are stored on a Windows Home Server-based system."
