Windows 7: KB3133977 Issues With TBS Service

26 Dec 2016   #1

Windows 7 Pro SP1 x64
KB3133977 Issues With TBS Service


i just happened to notice a service failure in 'services.msc'. The TBS service had a failure, was set to manual,

displayed an error code 2. When attempting to start the service, error 1083 appeared and it wouldn't start.

I located 'TBS.dll' in System32, and 'tbssvc.dll.mui'.

It appears update KB3133977 is the culprit. I removed the update and TBS disappeared from the

'services.msc' menu. Apparently the update has something to do with Bitlocker-

'BitLocker can't encrypt drives because of service crashes in svchost.exe process'

So, does removing the KB mean that Bitlocker won't encrypt the drives?...'BDESVC' is set to manual in


Thanks for any input on this matter...attached is a photo of the DLL's from TBS.
