CCeaner causes Warhammer Online to re-patch

CCleaner for Windows
1

I've been using CCleaner without any problems for years now and actually donated because I've been so happy with this great piece of software. Last November, however, I started playing Warhammer online and the strangest thing began to happen. I would download the full patch for the game (very large patch!) and would play just fine for about 3-4 weeks. Then I would log-in to try to play, but the launcher would begin the whole patch process again from scratch. It took ages before I realised the connection between CCleaner and the re-patching process.

I began to have vague suspicions that this need to re-patch would occur after using CCleaner, and today, I tried it out. Warhammer Online was working perfectly, so I used CCleaner as normal, and afterwards tried to log in to Warhammer. Ahah, the eureka moment - the game started to download the huge patch again. So this time I used my saved copy of the reg files which CCleaner had deleted, and yay! after the registry files had been restored Warhammer Online was able to play without downloading that massive patch. So, I'm guessing that somehow CCleaner was deleting a reg file that was needed for the client to access the patch or somesuch.

Anyone else come across this problem, and does anyone have any advice or possible solutions to offer, please?

Thanks,

Jay

p.s. I might have sorted the problem myself. I added the registry keys which I think pertain to the update to the list of items to be excluded from registry clean, and so far, so good :)

:) Jay your story is good reading for users who like to clean the registry, in that one should always backup!

Good point, kroozer. I do always backup and I have tried restoring the backups, but it didn't resolve the problem of re-patching. Sorry, forgot to mention that.

Perhaps post that .reg key area so the CCleaner dev team knows what they are. Also wouldn't hurt to tell the game developer, who knows they could change something to protect against other cleaning tools doing the same.
