After installing Windows 7068 I have had problems with the Ricoh xD card driver
from MS update. First time BSOD for me with Windows 7.
So far this is the only version that has presented this problem. Even downloading the driver from other sources does not help. It installs the driver and then I get this Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
Finally decided to just leave it alone and see what happens.
