Windows 10: "Invalid Handle" running Windows 10 in emulation with Parallels on Mac

    "Invalid Handle" running Windows 10 in emulation with Parallels on Mac


    Since updating (1) Windows to 10, (2) Parallels to 12 and (3) the MacOS to 10.12 (Sierra), logging into windows takes about 10 minutes. First the machine gives me a blue screen with the large word "Administrator" (the only user I have, i.e. me) and "Welcome" with the spinning little dots. For about 5-8 minutes the machine seems to be doing things, accessing disks and the internet. Eventually it gives me a message "Invalid handle" and what appears to be a box for a password but I set it up so as not to require a password. Indeed, if I leave the box empty and click the arrow just to its right my machine will boot and run the software I normally use (the basics plus Quicken): Total time nearly 10 minutes.

    I have researched the fixes posted in various places - Fix All The Things: Windows 10 - Handle is Invalid at Logon - 6 month or so ago, but I am using different emulation software, a different OS and Windows is much updated since then. I nver had this problem until the 3 interfacing bits of software (Windows, Parallels and the MacOS) were all updated. Niether the Parallels nor the Apple support folks seem to be able to help and the earlier posts on the subject such as the link above from february suggest this may be a Windows issue.

    Anybody else experiencing this or have a fix?

    I have been running windows 10 on Sierra for a few weeks now and the problem you describe just started happening for me. I enter my password, spinning dots next to welcome for several minutes, then sometimes I get "invalid handle" and sometimes it logs me in, but the shortcuts in the task bar do not populate and I get an hourglass whenever I try to click the start menu https://puu.sh/rrf0P/7fd45bfa51.png (note that my usual taskbar does not have Edge or the Shopping shortcut either).

    Having same problem


    Has anyone found a fix for this? Is there anything in the Parallels knowledgebase?

    I likewise have been having similar problem since last Windows 10 update on 10/27, but have not been able to uninstall as of yet.
