Oops - forgot to mention ... had done that already!

Thanks for your help Shawn. When I have some idle moments, I'll try the last step of extracting the files from the installation DVD.

P.S. Failing all else - your opinion, could this work? Win7?s no-reformat, nondestructive reinstall

Yes, a repair install should be able to fix them without losing anything. However, if you're not having any issues, then that wouldn't really be necessary to do unless you just wanted to.

Thanks people, I downloaded the new Mavericks theme pack and I couldn't restore my laptop to the original uxtheme files that the patcher it came with patched on my own. The SFC Scannow feature of Windows 7 has REALLY helped by ending my search. I have it running now. Thanks a lot!

Hello!
There are some files system in my machine running Windows 7 Ultimate Service Pack 1 (32bit) which cannot be fixed by the SFC Scannow tool.

I enclose the CBS logs for further investigation (I've used this magic FREE & PORTABLE app for that: Read and analyze Cbs.log Free Download)

It shouldn't be a serious problem though, because my system is running smoothly except for 2 key functionalities:

1) Windows Update function
2) Restore Point function

As for the first issue, whenever I launch Windows Update it fails to show me if any possible update is required.
All warning messages refer to error codes related to the impossibility to gain access on Microsoft servers.
Please note that I run, as a PC Tune Up tool an excellent free Chinese tool called "Baidu PC Faster", which does have a module called "Smart Update" that actually replace the Windows Update function.Have you ever heard about it before?
According to its developer this function is better than the Windows Update one, since it gives you smarter updates for you system: in fact it has found about 20 security patches needed to be applied on my system missed by Windows Updates itself. However, once unchecking their own update funcionality, Windows Update still doesn't work at all (getting the same error codes as mentioned above).
What do you make of it? Is in your view their Update function really better than the Windows one?
And why the heck is Windows Update not working even when their function is disabled?
Could it be blocked by their service running in the background (Baidu PC Faster Service 4.0.0.0) or is this problem related to some missing files system that the SFC Scannow tool cannot repair??
Please note than I've also tried to disable their service mentioned above, by using the freeware "ToolwizCare", but unfortunately my attempt was unsuccessful since Toolwizcare failed to do that.

As far as the second issue is concerned, whenever I try to roll back my system to a previous restore point, Windows and any other third party tool are not able to do that, even in SAFE MODE: again, in your view, what could be the cause of it? Could it be related to a missing file system as well (see attached CBS logs for more details)?
If so, how can I fix this annoying issue without being forced to reinstall my system from scratch?

Can't wait to hear from you.

Hello giovy,

If you have not already, you might see if doing a system restore at boot may work instead.

Hope this helps for now,
Shawn

Hello Brink!
Many thanks for your reply. I'll try to do a system restore at boot as soon as I can.
Unfortunately I deleted most of my previous restore points (the oldest one) in order to freeup disk space, so I'm not sure that this will solve the other issues I mentioned above.
Wait for your feedback about my cbs logs.

Looking at your CBS log, SFC only shows your Music, Photo, and Video samples files as missing and unable to repair.

These files are nothing to worry about though since they are only the default samples included in Windows.
