is it possible that ccleaner is removing Win 7 MC's reg values for mcupdate.exe ?

[T Rush]

...I was thinking it was one of the Windows Updates that installs that would not allow the mcupdate.exe to run automatically by Windows 7 Media Center...as the Guide would display "no data available" unless you went into C:/windows/ehome and manually right clicked mcupdate.exe and chose 'run as an administrator' to get the Guide listings back
..another symptom of it not running is that if you rerun the "TV Setup" for your tuner you get this:
"TV Setup Cannot Continue : TV Setup has encountered a serious problem. Select finish to exit, then try again. If the problem persists, restart Windows Media Center or your computer. : PRERELEASE Exception: Element not found. (Exception from HRESULT 0x80070490)"
http://windows7forums.com/windows-7-...-tv-issue.html

Google'n I've found a few people that have those exact two problems..but not everyone has those problems(as if it was obviously from an Update everyone installed)...and really the only "fix" I've found is to do a Windows 7 "repair install"(basically you just start the Windows 7 installer and pick "Upgrade" to rewrite your OS)
...but now I've discovered a third problem that might be related, and it is that some very basic remote controller button functions stop working in Media Center(like volume, pause, FF, RW, stop, etc.) where others will still work('OK" and arrow keys, and direct menu buttons)...all four of the Window 7 computers I run have the 'mcupdate.exe' problem, and three of those systems use a remote with the now non-functioning buttons

all this stuff works great when I first setup these systems, or if a 'repair install' Win7 was first done, but then those stop working after <something> happens....I just did a repair install on one system yesterday, but then installed updates and ran ccleaner and lost those features, so those are the two things I "think" could cause the problems

if I knew it was Windows Update I guess I could hide or stop the update that causes the problem if I knew which one it was, any ideas? here are the updates that installed after the repair install of Win7 http://i33.tinypic.com/8zp44m.jpg

if it is ccleaner that is messing up the registry by removing values that it thinks aren't needed, can I stop that or do I just have to not use ccleaner at all ?

...its seems it must be one of those things, as after a 'repair install' of the OS, and everything is working again... thats really all that I do, or needs to be done besides a good defrag

could it be something else? or is there some way to get these things working again without doing the complete reinstall of Win 7 ?

the 'no data in the Guide' takes time to detect, as it holds something like 3 weeks of data before you find out its not updating...and the 'TV setup cannot continue' only happens if you rerun the tuner setup(so I guess I could use that as a test for when the issue happens)...the 'remote control non-working buttons' I've just discovered as a possible related symptom(I noticed it on one computer some time ago and never investigated, but now I see its with all of them)...but I guess I would have to painfully spend a bunch of time, installing one update at a time, and then trying to detect what/when the problems appear, and test if ccleaner messes things up, after another repair install on the OS...tho right now(at least with one of the systems) I don't have that time to go thru too much of that because I would like to sell it tomorrow

Let's assume that these 706 entries really are a problem. Thing is, removing them doesn't do anything at all to help performance. Sure, the registry gets smaller, but such a small decrease in size doesn't make it measurably more efficient. Arguably, removing some of the unnecessary entries can help security, but at the point they're an issue, your system is probably already running arbitrary code without your knowledge..

...so now I'm really wanting to blame ccleaner for stopping Windows 7 Media Center from functioning properly...or what else could have caused this?

I'm open to any ideas before I start the "repair install", and begin the whole process again

First, why do you need to run CCleaner and defrag after a fresh install of Windows, or a repair install, for that matter?

Second, how does System Mechanic == CCleaner? Regardless, if you think entries removed from the registry by CCleaner might be the problem, why not just use the backup .reg file it created to re-inject those entries back? If CCleaner did it, reverting the changes it made ought to resolve the problem.

Third, are you allowed to sell computers with Windows 7 RC installed?

oh, just 'maintenance' I guess?
... as well as running Windows' own "Disk Cleanup" to remove any temporary files or old discarded files from the old Windows, and then defrag just seems like basic hard drive cleanup....but I'm wondering about 'fixing' or removing those unused/incorrect registry values with ccleaner, how much that can 'help' or if possably it is doing much more damage than good

I was just thinking the two apps might do the same sort of thing...and yeah, that would be nice if I had ever used that feature to backup the registry..but I didn't/don't(if I try running ccleaner on Windows 7 again, I will)...I've just ever needed to on any other OS

its a computer i built for a friend, and he wants Windows 7, I thought about buying Vista for him and installing that, then doing the Win 7 upgrade when that is available....but, he has heard a lot of bad things about Vista, where people have told him Win7 will be great...so I just stuck the "evaluation copy" of Win7 RC on there for now, and then told him he will need to buy Win7 after Oct. 22nd when it comes out, but before next summer when the Win7 RC evaluation expires
..certainly I'm not charging him for Win7 RC or selling him any software...basically I just picked the parts(hardware) for him, reusing some things I had(the case and BluRay drive, which I'm slightly discounting) and just giving him the bill for the new parts that I paid for from newegg

but i don't see why anyone couldn't sell hardware running evaluation software...seems like OEM pre-built computers/laptops come with loads of that stuff on there, like Systematic anti-virus and MS Works/Office trialware failware etc.

I think you need a stronger reason.

You can set an ACL on the registry entry to stop it being removed. You can also try running a program to monitor the registry to see what ccleaner is doing. Or, backup the registry before, run, then backup again and compare the differences. (This works, but it's quite tedious.)

[T Rush]

well then I don't understand(note that I'm horrible with software)

I think that I'm learning that removing/'fixing' unused and incorrect registry values could possably do more harm than good(and might be the cause of my problems here)

but doing simple maintenance of file cleanup(like the discarded files from the old Windows install, temp files, and emptying the recycle bin etc.) and defrag.. are not recommended after a dramatic change to the data on the hard drive like a repair/upgrade OS reinstall ? or at just regular intervals



anyway, does anyone think that ccleaner(and/or file cleanup/defrag) could have the 'power' to cause the problems I'm having?...what about Windows update?...or am I just fighting a Windows 7 pre-release/beta/RC "bug"?...if so why can't I find more cases of these problems, like shouldn't everyone have these issues ?
..I just don't know, I'll start another repair install, do all updates from Windows Update...and not do a cclean nor defrag and see if the remote, Guide, and tuner setup still all work *sigh*

notably these issues have happened to 'some' other people, but not everyone...so I'm thinking it might be something that 'we' are doing to self-inflict this on ourselves, that other people might not do?...so it seems that might be ccleaner? but I can't track down everyone who had the Guide/tuner setup issues and ask them if they also used ccleaner

Of course a utility like that has the power to mess things up in the registry. The registry is what contains all the settings for how applications are supposed to run. You really shouldn't have to run any app like that since Microsoft provides all the tools necessary to keep things running properly without the need to run any third-party app to muck with the core components of the Windows OS.

[T Rush]

I guess...but I've never had a issue like this with it on other OS'
..I was thinking ccleaner was 'safe' and actually good to run, but I guess I was wrong
...well anyway, the proof will be in the pudding, I'll uninstall ccleaner and do the 'repair'/upgrade install of Win7, and hopefully that will be that, and I'll give up on using ccleaner

[marie pavie]

I don't use any of those app's anymore. I think they're good for learning about the OS, but...

[T Rush]

well i just feel sick now...as I don't know how much trouble these problems have caused me with the 4 computers I've installed Windows 7 on, and then those other people i found fighting these same issues without prevail...only to discover that after every repair install I did to fix the problems, I immediately self-inflicted the issues right back again with ccleaner

as now the system is running fantastically after the Upgrade/repair install of Windows 7, this time without doing a registry cleanup/fix with ccleaner...so thats something I'll never have to download again

I don't know what starting me thinking it could be causing the problems(I guess because it was one of the only two things I did after the problems were fixed to "re-cause" them )

ok so now all will be well with my Windows 7 homefront(after I remove ccleaner and do the repair OS install on the other 3 computers)

but I'll toss this reg-edit question in here too(if the good people of SUF will ever let me touch a Windows registry again)
so...Windows 7 does not have the option to set Media Center as the default player for anything in the auto play settings like Vista does
here if you don't believe me
Vista screenie http://www.sevenforums.com/attachmen...oplayvista.jpg
Win 7 screenie http://www.sevenforums.com/attachmen...-autoplay7.jpg
..but while I was searching for a fix on my above issues, i came across one of these little .reg files you can download and run to write the values needed to make the DVDs auto play in Media center option available
http://www.sevenforums.com/media-cen...tml#post277901

however how do you make one of those(isn't just a .txt notepad doc you rename the file extension on?) or how do I manually enter these values to auto play BluRay disks in Media Center(yes I have Power DVD installed to support BR playback in MC)
http://www.sevenforums.com/media-cen...tml#post222438

[crazycanuck]

if your using the registry cleaning option in Ccleaner there is the option to backup the registry changes before you accept the Uitility to make the changes. If you have been diligent and using the "create a backup" option then you have the files on your system to erase the changes ccleaner has made to the registry and restore your registry.

Here is some reading for you:

http://support.microsoft.com/kb/310516

[T Rush]

so I should just navigate the registry and add the value:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\AutoplayHandlers\EventHandlers \PlayBluRayOnArrival]
"EHomeDVDDropTarget"=""

...to get the auto play option for Media Center under BluRay(or chicken out and leave it alone...as you can always just open Media Center and hit 'play DVD' which causes PowerDVD to run within/on-top-of Media Center with a BluRay disk in for playback, otherwise it will play a normal DVD without PowerDVD in just MC...and select 'take no action' for when a BluRay disk is inserted)
[note that this is unrelated to the main subject of this thread]

yeah, but I don't/didn't bother doing that...and even if I did...I still don't know the registry values that were changed/deleted to stop mcupdate.exe(that updates the Guide) nor even what would have caused the "TV Setup Cannot Continue :PRERELEASE Exception: Element not found. (Exception from HRESULT 0x80070490" error(if that was mcupdate reg value too?)...or what about the remote control losing its stop/RW/FF/pause/volume/channel button functions...and now i wonder what other things ccleaner might have effected in Windows 7 registry that I just hadn't noticed?, or that there might be odd program cashes that could be periodic mysteries

...I just don't trust ccleaner as being so benign in Windows 7 "RC" build 7100 any more

(tho I still ran disk cleanup and defag...those might be harder for me to give up...but seriously, those are still 'safe' and somewhat beneficial aren't they?)

[crazycanuck]

I can't stress this enough...any utility that cleans your registry should have a backup option and you should always choose to accept that option.

Regscrubxp used to back up automatically for you and it was very easy to restore.

Clcleaner is a very very safe program used my literally hundreds of thousands (or millions) of people worldwide without issues. Personally if you have to go through a few extra steps to get a dvd to play over using the autoplay function..its not a big deal and safer then tinkering in the registry.

yeah, I've used it on XP and Vista without any problems at all
...but it seems that on Windows 7 "RC" build 7100 it mysteriously removed/changed values that are needed for the correct functioning of Media Center(where those features still work fine when ccleaner was used on Vista and XP:MCE2005)
...I don't doubt at all the the other people who reported the "no data in Guide" and "TV Setup Cannot Continue" problems might have also run ccleaner or another registry cleaner/'fixer', and still might not have a clue that this is what caused the problems, and could fix them(possably) by restoring a backup to the registry...as all the results that Google had ever turned up(I've been dealing with these problems over and over again for months now and no one was able to resolve what had caused them, nor how to fix them, in my web searches)...now we know that the Win7 "RC" build 7100 does not have all the necessary registry values 'protected'(or whatever) from these types of 'reg-cleaners'

oh, the deal is that the Win7 "Default Programs" interface does not include Media Center as an option to autoplay DVDs(and you can't browse for it), here is your only default options http://www.sevenforums.com/attachmen...-autoplay7.jpg
...unlike Vista which does
to get it as an option in the drop down list, you have to edit the registry( autoplay-dvd-movie.reg 2.2 KB download )

hopefully in the final release of Windows 7, there will be that option(and hopefully the registry will be better protected?) as well as I wish Microsoft will add the Netflix Silverlight player in Media Center(like they have updated Vista to) and [crosses fingers] natively supports BluRay playback without the need for a third-party app/plug-in

ccCleaner -> Win 7 -> Breaks Windows Media Center

I installed and ran ccCleaner (downloaded 10/02/09 - Don't remember the version) on Win 7 RC X64

ccCleaner Removed some registery keys but WMC worked fine UNTIL I rebooted.

I had these problems with WMC after reboot:

1. Multimedia keyboard keys did not work (Mute, FF ect.)
2. WMC would not download the EPG anymore
3. WMC would not automatically record. It would not do a scheduled record but I could do a manual record.
4. I tried to setup my tuner again in WMC and the Regional Setup Download hung.
5. I was able to get WMC to setup the tuner but on the last step I got the message PRERELEASE Execption: Element not found Exception from HRESULT 0x80670490
6. I deleted the ccCleaner back up .reg files but deleted them because everything worked fine until I rebooted.
7. I made an image of C: drive before installing ccCleaner with Acronis and restored this image and every thing worked fine again.
8. Do not use ccCleaner on Win 7 with WMC as it will toast WMC. If you don't have a backup or aren't able to merge ccCleaner backup .reg files back into the registry you will have to do a clean install of Win 7
9. The current version of ccClean TOASTS WIN7 WMC.
