Unfortunately, the error message that Windows displays when error 0x80070BC9 occurs is not particularly meaningful. However, you should carry out the following steps to eliminate the error and install the missing Windows updates.

Clean up update store

As a rule, problems with the Windows Update Store are often the reason for such update messages. For this reason, you should delete or rename the directory in which all downloaded Windows Update files are located. The easiest way to do this is to start a command prompt, which must have administrator rights.

Then you execute the following commands in sequence.

net stop cryptsvc
net stop wuauserv
rd / s / q% windir% SoftwareDistribution
del% windir% WindowsUpdate.log
net start wuauserv
net start cryptsvc
