Q: ITunes keeps asking me for a password to "Sign in to use this computer for automatic downloads"

I fixed the problem by deauthorizing my computer in iTunes.

Yes, that means needing to have an iTunes store account (or at least an apple ID), but I've never bought anything on iTunes and probably never will so deauthorizing was no big loss.

same problem.

another solution:

disconect your account from itunes store in your itunes.

in your itunes on itunes store, right upper corner click in your email press disconect

when you reopen your itunes it wont ask again

Hi,

This happens to me too, and restarting as an administrator in Win7 does not solve it. Thing is, it also kills iTunes Match, since at restart it does not update (see https://discussions.apple.com/message/17418196#17418196 ) I believe these two bugs are related since for some people the "run as administrator", de-authorize, re-authorized solution works.

Worst of all, it seems Apple does not even recognize the existence of the bug!!

I have experienced the same problem. Here's what worked for me.

I did all three so I cannot say for sure which step was the successful one.

(1) iTunes > Preferences > Store. Uncheck everything that has to do with Automatic Downloads. (From now on if I want to check on the status of any downloads I will do it manually. No big deal. That beats having to enter my password every time I launch iTunes.)

(2) iTunes > Store menu. Select Authorize This Computer. The response is that it is already authorized. The thinking here is that it resets the authorization.

(3) iTunes > Store menu. Turn off Genius. (Bummer, because I kind of like Genius. Oh well.)

(4) iTunes > Preferences > Advanced. Click Reset Warnings and Reset Cache. (Again, clean house to see if that helps.)

So far this has worked. No more constant requests for my iTunes password upon launching iTunes.

Thanks, number (2) did the trick for me.

The parental tab workaround worked for me! Thank you.

#2 fixed it for me too.

Thx.

(2) iTunes > Store menu. Select Authorize This Computer. The response is that it is already authorized. The thinking here is that it resets the authorization.

in another thread, for the Mac version, it was discovered that resetting Safari (which deleted cookies) also deleted information stored by iTunes. A window user there found something similar in he used a cleaner to delete cookies and set it not to delete anything apple and it fixed it for him.

ITunes has been my dedicated music player for over a decade, but this bug was the last straw.  I switched to an alternate player and will be using that alternate player from now on.  I'm sick of the focus being on whatever top of the charts music apple peddles rather than the music that I love in my library and my playlists. 

Yeah the deauthrorization worked, but I shouldn't have had to do that.  This problem should have been rectified ages ago. 

After the new 10.6 update the message dissapeared

I just had to enter my credentials once more and now it opens and closes OK. It also fixed iTunes Match, which was also giving problems.

I hope the update also fixes your installations!

from the therealjg...

(2) iTunes > Store menu. Select Authorize This Computer. The response is that it is already authorized. The thinking here is that it resets the authorization.

this, SO FAR, is working for me. I'm using mac's BTW.

I will report back, and encourage EVERYONE having this problem to try this.

try suggestion 2 here...

after half a day with this tip i can report back that it doesn't work continuously.

we go on...

iTunes started doing this again tonight - I searched a little more on Apple's support and found this article: http://support.apple.com/kb/TS1389

Try option 4 - Remove the SC Info Folder
