After running official MS method of cleaning WINSXS and using tools like PatchCleaner my WINSXS folder is currently 13.8 GB and you can't seriously expect to get it to a much smaller size after running those tools.

You can disable hibernation to save a fairly large chunk of drive space. You can also periodically clean logs if you don't need them because your system is running okay.

Also you could run an ADS scanner to remove only safe ADS.

How do I delete zone identifier files?

You can use this to find and remove .bak files. Just add them to the include list.

Run a scan and inspect results. Uncheck anything that you don't want to delete.

Windows 7 (My Idea)

Well you can only clean it through the Disk Cleanup utility, located in Accessories/System Tools on your start menu- Don't ever try to randomly delete files yourself, but the tool should remove a bunch of your bloat. When you run that tool, you want to choose the very bottom checkbox, that's the one that removes the stuff in "winsxs". It says "Temporary Files", but you should also check "downloaded program files" You can check the other selections at your leisure, but I generally run all of them.

As far as the "bak" folder, I think it's safe to delete that, in your case it was probably created when you ran the Windows Update repair Diagcab at one point. That's the folder where your downloaded windows updates are saved, if the diagcab repaired Windows Update, then it should be safe to delete that backup of the original corrupted folder.

You can also try CCleaner free version, it will delete all kinds of backups. Just download that and run it, I would not be surprised if it finds and deletes up to 10gb of bloat. Be prepared to wait a long time while it populates the files, but don't close the app, let it run, then delete the files it finds. There are two buttons, "analyze" and "clean", run analyze first, then clean.

On systems where I have never run that tool, I've found all the way up to 10gb of temp files. But try the built in Disk Cleaner tool first.
