Windows 10 1709 file permissions issue

[Dashrender]

Some of you might have seen my post this morning about PDFs not opening in IE.

After showing another error from these machines - JB told me that he's seen several situations where 1709 is having permissions issues.

So this could be a 1709 issue specifically not giving permissions.

Additionally I found that Webroot has a known issue (also around permissions) on 1709.

Well disabling the realtime scan on Webroot has solved my issue.
