While CCleaner is one of the best Registry Cleaners available for Windows. However after using it (v2.23.999) with my Windows 7 x64 RTM I found that I lost the Bitlocker options from the context menu.
After some search I found a post by MVP Ramesh shows that use of CCleaner is likely to break the Windows 7 right click context menu. He also offered a registry fix to restore the deleted items from the registry and so the missing context menu.
Still after restoring the bitlocker to the context menu, ccleaner marks these entries for deletion every time I analyze the registry.
I though that reporting this bug here might help taking it into consideration in the new update, ccleaner is an excellent tool and it is so bad to cause such problem.
