Comment(by bastik):

 Replying to [comment:3 nickm]:
 > I wonder, could this be another instance of #2077 ?  If so, does any of
 the discussion there seem relevant?

 Looks like this would be the same issue. I'm not sure what's relevant.
 However based on the ticket I can give the following information:
 File flags for %APPDATA%\Tor (I don't know how they are named in English
 versions of Windows)
 write-protected/read-only: not set
 hidden: not set
 archiv: set (file can be backed-up)
 index content: not set
 compress content: not set
 encrypt content: not set (grayed out, not available)

 I (disabled publishing my descriptor and) started Tor.
 [...]
 Mai 09 08:23:49.039 [Warning] Error replacing
 "C:/Users/[username]/AppData/Roaming/tor\cached-microdescs": Permission
 denied
 Mai 09 08:23:49.039 [Warning] Error rebuilding microdescriptor cache:
 Permission denied

 I launched ProcessMonitor (before I launched Tor) to provide information
 what accesses these files. I'll attach an excerpt of what was logged. Tor
 could write to .tmp, but could not remove the "cached-microdescs" file.
 CANNOT DELETE. There's no race between two processes accessing the
 file(s).

 I never had this error prior to 0.2.4.12-alpha and wonder if there was
 change.
 #8037 is mentioned in the change-log. I don't see what would cause this.
