I'm having the same problem: the Windows 10 anniversary update got as far as 99% and has sat there for 10 hours now without moving. I guess there must be a problem with it. I'm leaving it running while I'm at work but if it hasn't progressed after another few hours I'll have to risk restarting. I wish Microsoft would put in some failsafe mechanism to give users recovery options if the installer has stalled for an unusually long time.

I am trying 3-4 ways to update my November updated WIndows 10 to Anniversary.
Windows Update in Windows 10.
Then: two ways here MS link below at Microsoft ... Update now or Download Media Creator Tool..

Windows 10

Media Creator Tool just says Checking for updates and I expect this to NEVER end and tell me what to do like all the rest.

All just hangs for days on end. I expect this like 99% below exes to NEVER END POINT and tell me I need to do something else. Dumb! Sry DUMB.. they are hitting some wall and just keep hitting the WALL! No end point.

Windows10Upgrade9252.exe
Windows10Upgrade28084.exe

Both ABOVE from Microsoft download and and hang at 99% with no tip to do anything to fix bug ..it will go on forever. (They are hitting a wall and have no response except to KEEP hitting HEAD ON WALL.)

I would be NICE if these major updates would also just repair components in Windows but they do not. Just Balk at end. My November Update worked!

My SFC /SCANNOW shows problems:

Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios.

Tried SFCFix.exe from some site which just seems to be SFC /SCANNOW and DISM command in a package command ...nothing special.

Tried prior:
DISM commands as admin say "repairable components" ..in check Health:

Dism /online /cleanup-image /scanhealth

Dism /online /cleanup-image /restorehealth

Claims no Source found.. ..I point to new Downloaded Source with Windows Media Creation Tool and same... Says no Source found even though I pointed to new SOURCES .wim or .esd too on disc with the latest mounted .iso from Windows :
Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:N:\sources\install.wim:1
or stopping online update or both in Safe Mode.
Dism /Online /Cleanup-Image /RestoreHealth /Source:wim:N:\sources\install.wim:1 /limitaccess

RESTORE HEALTH commands cannot work pointing to CURRENT MOUNTED .ISO SOURCE!
Even with a Mounted current .ISO of WIndows 10 pointed to as SOURCE in SOURCES commands in DISM

I am working on TRYING TO MAKE a SLIPSTREAMED .ISO and or DVD in order to do a nice classic REPAIR/REINSTALL with a .iso or DVD with MY MATCHING VERSION OF WINDOWS 10 or it will NOT WORK I am TOLD. I need the NOVEMBER UPDATE IN THIS!!!! Maximum PC says it will take a long time to have it. Windows 10 Microsoft does not SAY which version MEDIA CREATOR TOOL is giving you and whether on not it has the November updated included.

How to Slipstream Windows 10: Create up to date Windows 10 ISO files with all available Windows updates - WinBuzzer

I think I need to have a FULLY SLIPSTREAMED version of my WINDOWS with NOVEMBER UPDATE and latest updates for my current version with Nov UPDATE in ORDER TO DO a REPAIR/REINSTALL of my current version to repair Windows and NOT lose my 365 Games installed and config. I cannot do a Clean or Reset or other.. Then maybe new update will install.

Current DOWNLOAD Windows Media Creator Tool .ISO Windows 10 should be the VERY LATEST so I can do this from this .iso.
I have Version 1511 (OS Build 10586.494) . I doubt this is what is in the latest WMC Tool .iso Download.

Think of the billions and billions of variations there are of Windows computers, in terms of hardware, software, and driver revisions. It's impossible to upgrade 350 million PCs without some issues. What gets many of us riled up is when people mistakenly assume Microsoft is at fault. Besides, simple logic says, if everyone has a problem, blame the OS. If less than a fraction of 1% have an issue...then the OS is probably just fine. Including work computers, I've upgraded close to 50 computers of various ages and processing power. I haven't run in to a single issue yet. That would be impossible if Windows 10 was the problem.

And this helps with the problem exactly how? Other people may have different experiences. I've updated dozens of computers with various operating systems and if there were problems it were invariably the windows machines. Some stuff has to be more reliable than other stuff. You cannot have the breaks of your car working 99% of the time, or the fire fighters putting out the fire 99% of the time. I paid good money for a working operating system and I need it to work always, not sometimes. Anyway, there's always linux.

I had the same problem on my Windows 7 laptop. Got stuck at 99%. It had to download and install some W7 updates first. After installation everything went smooth, and no further problems:)

Somewhere in the posts at this link in Ten Forums I reported my success on fixing: Repair Install Windows 10 with an In-place Upgrade - Windows 10 Forums

I think it was running the Windows Update Repair Tool, which added a Windows 10 version midway and finished showing a bunch of errors and solved ..but just came back and solved on running again. I think I had to take control of Catroot2 and run these Repair Commands in CMD as Admin.. anyway... Windows Update in Win 10 finally got it installed and acted like a Repair/Reinstall in some ways... SFC /SCANNOW says no errors which has been a bug with me for months and DISM commands did not work, even pointing to a SOURCE of Fresh .iso DL. But, I still have "Service registration is missing or corrupt Not fixed" in WINDOWS UPDATE TOOL. SO ?? Not a Real Fix on this bug.

I'm glad it worked for you. I cannot go back to windows 7, unfortunately. Also, I noticed that yet another laptop now shows the same problem. It's a crappy OS.

I always Trust Microsoft Updates all the way. There are bugs here and there with many Systems which have wildly different setups. I have found that it always pays off to just Keep up with MS. It is very self correcting in the end. Beautiful ....I always go for the latest. A little Googling on bugs usually will find a Fix on this on that.

wow thats a lot of time
might want to try other solutions here

This might work for someone out there even if I'm late. Windows update tool got stuck at 99% on my computer. All I did was restart, then go to C: and enable viewing of hidden folders. Then I was able to see the folder where the update was downloaded to, in that folder you'll find the full set up and just run it manually. It worked for me and I was up and running in 30 minutes
