If you can boot to safe mode, you can uninstall recent updates manually:

Windows Update - Uninstall an Update - Windows 7 Forums

Hi

If you have a Windows 7 disk, it sounds like time for a repair install to clean things up and get things back to the default settings.
Even though it shouldn't loose anything I'd back up all my important data first.

Repair Install - Windows 7

Once you have your computer up and running again make a full system backup to an external drive so that you can get it back to the present state easily.

thanks for your help again but i don't think it will help me

even in safe mod i cant uninstall the windows defender updates (they even wirte in the update "once this update as been installed it cannot been remove")

and repair my pc is out of the qustion, my system is stable and i maintain it every month, repairing the system just will make it even more unstable and from what i read in other people's forums that haveing the same problem it dont work for them.... help?

OK, since most of this thread seems to revolve around Windows Defender and potentially the updates to the program that may be at the root of the problem. Have you considered disabling the service just to see if that has any impact. Type services.msc into the search box and hit enter scroll down to Windows Defender and double click it.
See attachment.

thanks i will try

i actually think about it today and stop windows defender without the service msc (insted i just go to win defender and deleted the "V" that said "stop services" )
but i still got BS today... however i surprisedly was able to get out from it today.. but i not sure it will work for me again

anyway thanks i will try what you said ,and will test it (...take some time... i cant tell the BS to come when i want XD) and will report back to tell you if its work out : )

thanks for the help Mikehawthorne

but i allready check it long ago when i try the PREVX fix
from what they write it seem that the windows defener and the fake clock update was some of the main case to the BS

however PREVX said they not sure themselves what the main cost of the BS because from their report some people get the BS without the these updates...

I don't think that cybercore was actually referencing the windows defender update. More likely a couple specific updates. You said that you tried the Prevxx fix in the article that MikeHawthorne references above. That same article points to two specific updates
KB915597 and KB976098
So I'm wondering, did the Prevxx fix, remove those two specific updates? Have you checked your "Installed Updates" to make sure that they are not installed?

ok after testing of allmost week (more like half week) i not getting BS after i turn off the WINDOWS DEFENDER however ysterday i get one just when i put my disk-on-key in the pc....but i was able to get out from it really quick.... (its just me or win7 not really love disk-on-keys? everytime i put in any sort of disk-on-key and then finish with it and put it out my pc start to acting wired... if i try to make new floder, copy something or paste something the pc just stuck with the "thinking" mouse icon working and the start line become transparent and all the pc freez until i do restart.... all these things happends ONLY after i use disk-on-key and only after i put it out...lucky for me it all fixed after restart through...) anyway its hard to tell if my BS days are going to be finish....however i can say clearly that the WD took big part of it. ┐(￣ー￣)┌

o btw as answering for Truble (sorry i not saw your qus XD) no this fix not remove anything

you can read what this fix done in their site.

i check these updates and one of them is WD update and the other is fake summer (or it was winter...) clock fix.
