Thanks for the info.
Some users reported high memory usage by DellDataVault if you don't use it you can use services.msc and change the startup to Disable on the 3 services it uses DDVCollectorSvcApi, DDVDataCollector, DDVRulesProcessor
I did request before to try the Windows Update in Clean Boot mode I just want to confirm if you also made sure the software from Fujitsu isn't running and also the Microsoft SQL server.
