unable to acces certain control panels from admin account

I am not sure when this issue occurred, but I noticed it today

Problem:
I am unable to acces certain CP from the admin account. These CP include "advanced system settings" and "remote setings". When clicked, nothing happens. So far all the unresponsive CP I have identified are "admin CP" (they have the little multicolored circle next to them) Odly, I AM able to acces SOME admin CP, ie. "device manager".
I have tried creating a new admin user from which all the CP works fine.
I have scanned for virus with AVIR to no avail.
I have scanned registry etc with Tuneup utilities, also to no avail.
Recently I seem to have lost a few fonts, like Times new Roman (missing from all users), no idea if the 2 issues are related.
Problems remains on safeboot.

Could this have to do with permissions? I have recently changed the UAC levels back and forth. (EDIT: just tried all four UAC settings. On the highset security level, UAC prompts me when I press the unresponsive CP, after I press ok, nothing happens. On the 3 lower levels nothing happens whatsoever...)
Just tried copying my user to a new user but gave it up as a reinstall seems more sensible.. gonna keep trying for a few more days though as I'd like to know what the cause of the issue is..


I am running win 7ultimate - 64 - slightly tweaked services and such, but nothing that I can immaginbe to cause this issue.
EDIT:
Upgraded to authentic windows yesterday, could this be the cause?
Service tweaks:
NET STOP "Adaptive Brightness"
sc config SensrSvc start= demand
NET STOP "TPM Base Services"
sc config TBS start= demand
NET STOP "Windows Biometric Service"
sc config WbioSrvc start= demand
NET STOP "CardSpace"
sc config idsvc start= demand
NET STOP "Windows Defender"
sc config WinDefend start= demand
NET STOP "Windows Media Center Receiver Service"
sc config ehRecvr start= demand
NET STOP "Smart Card"
sc config SCardSvr start= demand
NET STOP "Smart Card Removal Policy"
sc config SCPolicySvc start= demand
NET STOP "Offline Files"
sc config CscService start= demand
NET STOP "Parental Controls"
sc config WPCSvc start= demand
NET STOP "Distributed Link Tracking Client"
sc config TrkWks start= demand

+ several tweaks from programs like tuneup utilities and similar

Where do you see these CP items? They do not appear in my Control Panel at all. Are you talking about System Properties?

Hm!!!!! This could be the cause. Throw the tune up utilities away and try first a sfc /scannow. If that's no good have you got an iso back to before the problem started or look for a System Restore point before the problem!

The items concerned are here:

Right click on My COmputer and select Properties. Does that get you there? Should look like the image I posted, which is where the links mitchell65 posted take you.

doing sfc /scannow now, while waiting, I remembered that I also use "enhance my se7en" - another tweak app, should I get rid of that as well (and registrybooster?) before doing the sfc /scannow?
Tried doing a repair-install but for some reason windows claims that the disc I use is uncompatible (I am 99% sure that this is the USBstick I used for the install as I lost the disc when moving)
.. and unfortunately I am the kind of guy who turns off restorepoint and only do backup of his projectfolders..-...

Definitely, Definitely, Definitely get rid of ALL these tweaking and cleaning prog. They do no good at all. At best they do nothing at worst they cause the sort of problems you are having. Why did you think you needed them in the first place? Reg cleaners are not needed at all in Windows 7 as 7 treats the registry in a totally different and better way that any of the previous MS OP's.
Why did you turn off System Restore?
I think you have gone so far down the tweaking road that nothing short of a complete clean re-install of Windows 7 ill solve all the problems you have and those lurking round the corner. That's my view but you may like to wait for comments from others before taking that route!
