Hidden operation installation

[SCHHCC Tech]

Reference: ticket # 393? Environment: public PC with admin account. Upon windows logoff; machine is 're-imaged'. Requirement: No public person is to have access to BoInc? via the BoInc? tray icon. Other obvious routes can be hidden; less obvious routes, oh well. Approach: I have eliminated the MSCONFIG entry ...boincmgr.exe /a /s. This is replaced with a Task Scheduler enrty ...bioncmgr /a /m. Trigger is startup + 1 minute, running under a 2nd hidden admin account. This avoids the tray icon. results: Mostly works, however at times no processing is kick off. May well not be due to my approach. Question-1: Is boinctray.exe needed in MSCONFIG to launch under the active / logon admin account? Gossip says it is needed to honer the PC-in-use constraints. Question-2: Is it or was it ever true that the install option to run in protected mode requires a non-admin account to host the session, and does that account have to be non-batch? Question-3: The approach of 'protected mode' is known to corrupt the gpu for other apps? apologizes: As an old mainframe guy; I realize a trouble ticket system is not the place to ask questions. bottom line: Provide a concise step by step doc to allow a 'hidden' approach to running BoInc?.
