On startup, Windows 10 pops up the following alert:
An error has occurred in the program during initialization. If this problem continues, please contact your system administrator.
Error code: 0x800b0100
Windows is up to date and I've done my research, but
sfc /scannow and
dism /Online /Cleanup-Image /ScanHealth didn't fix the problem - the former just reported that there were corrupted files, not how to restore them (the resulting
CBS.log is several megabytes in size and not very helpful either).
The same error pops up whenever I try to access Windows Defender via the start menu - however, both
services.msc and the Windows Defender section within Windows Settings report that the respective services are active.
a) Can I safely assume that the machine is properly protected?
b) How can I get rid of this annoying dialog?
I'd very much appreciate any help.
