I'm using Internet Explorer 9 in a "normal" way, i.e. not doing InPrivate browsing, not having it configured to delete cookies on exit etc.

If Internet Explorer is open when my computer shuts down unexpectedly (either as a result of a BSOD or because it is being automatically updated) the next time I start Internet Explorer it seems to have lost many login cookies (i.e. for Facebook etc.)

I did some googling and found a thread on Technet forums describing the problem. User Snowknight26 wrote a detailed analysis of the problem in the thread:

From what I can gather, the index.dat file in the %AppData%\Microsoft\Windows\Cookies directory contains a list of websites and corresponding cookie files. After a successful shutdown, the index.dat file is populated with entries, but after a failed shutdown, those entries are missing.

Further reading his analysis it seems that after a failed shutdown the cookies are present but the index file pointing to these cookies is empty resulting in the cookies not being used.

Is there any solution to this problem?

I don't think there is. I have had the same problem and have ran across many people reporting to Microsoft on the MSDN forums with responses along two lines: Can't reproduce so not a problem OR not fixable. – Matthew Dec 1 '15 at 20:55

Yes, there's a quick solution, actually a number of them:

And others, such as Maxthon, or you could even set up Konqueror on Windows.

I'll quote a quote on FireFTP's homepage:

If you're havin' IE problems, I feel bad for you, son - I got 99 problems but a browser ain't one.

I have a solution:

You can use Linux.
It does not let you run IE*.
* Unless you install wine.

It's also a good cure if Windows > XP is corrupting your files.
