"Error code: 0x800706BA Error message: The RPC server is unavailable." I've tried the following but none of them fixed the problem: Checked to see if DCOM Server Process Launcher, Remote Procedure Call (RPC), and the RPC Endpoint Mapper services are running and set at automatic (they are); Used regedit to see if the start variable for these services are set at 2 (they are); Checked firewall to see if Remote Assistance is allowed (it is); Checked to see that file and print sharing and IPV4 and IPV6 are enabled in the network adapter properties (they are); Reset Internet Explorer; Disabled firewall; Uninstalled the antivirus (Kaspersky Security Cloud free); sfc /scannow (no problems); chkdsk /r (some orphan files, but no problems in subsequent scans); Went to safe mode; Logged into another account; Did a clean boot; Did a system restore using a point at 11/10 (the earliest available); Used a full backup from 11/5 (the earliest available); Ran Windows Repair; Ran Glarysoft Registry Repair; Ran ADWCleaner (some PUPs); Kaspersky, Malwarebytes, and Zemana scan (some PUPs); The only thing that fixed the problem was a Windows refresh, but many customizations (such as grey backgrounds for some apps) and software were removed, so I have to reinstall and reconfigure them. For now, I restored the whole system, with the problem still taking place. If there is a way for me to fix this problem without having to do a refresh, I'd appreciate it.
