Windows 10
Problems with Windows Update
Error 0x80244007
I got error 0x80244007 on a Windows 10 computer after running the Server Cleanup Wizard on the WSUS server. In my case, deleting C:\Windows\SoftwareDistribution\DataStore\DataStore.edb like suggested here worked:
del C:\Windows\SoftwareDistribution\DataStore\Datastore.edb
net start wuauserv
wuauclt /detectnow
Problems adding a network printer
Error #740
When adding a network printer fails with error #740, try running the following command from an elevated command prompt:
Then, add the printer using the wizard that appears.
It seems that this is somehow caused by problems with the driver installation in the regular “Add printer” wizard. After a printer has been added this way, other users should also be able to add it in the regular way.
I found this solution here.
Using UTC for the hardware clock
For historic reasons, Windows keeps the hardware clock in local time instead of UTC. This can be problematic when dealing with daylight saving time, in particular when more than one operating system is installed on the computer.
Windows can be told to use a hardware clock that is set to UTC instead (I found this information here):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001
For more information about how Windows uses the hardware clock, refer to this explainer.
