I am quite often uploading various big files to various websites with my web browser on a slow connection and not every website support resuming of the upload.

Now my lsass.exe process consumes around 1GB of memory and there is absolutely no known (to me) way to see what causes this memory usage, so I want to log out and in to fix the problem.

However I'm uploading a file which is 6 gb, and it's currently on 20% in 3 hours time. How can I ensure my browser stays open, even after I log off and log in to windows?

I did try to see if this memory usage is caused by any other accounts on the PC but there are no accounts with passwords and guest account is disabled.. and this is the net users output:

C:\windows\system32>net user

User accounts for \\GAMER

Administrator            Guest                    User
The command completed successfully.

You can't. If you want to find out what's using your memory, use RAMMap. – Oliver Salzburg Apr 22 '13 at 17:14
It seems like your actual problem is that lsass.exe eats 1GB of memory, but what you are asking for help with is leaving your browser running when you log off. Two different problems. Technically you could run the browser with srvany as a service account (with desktop access) and RDP into the service account or so, but this is a huge hack and probably won't work that well, esp. related to hardware acceleration, etc. You should just figure out why lsass.exe eats a gig of RAM. I am leaning toward virus since this never happens under normal circumstances if lsass is not corrupted. – allquixotic Apr 22 '13 at 17:21
Hm I fired up that progrm and go to lsass.exe and it just shows the 1 gb there, how do I find out exactly what uses what? And I doubt it's a virus - it's a 2 weeks old laptop and the only thing I did install with administrator rights were the drivers from the official page – user144773 Apr 22 '13 at 17:23
which (standalone)freeware antivirus can scan for such viruses? – user144773 Apr 22 '13 at 17:29
I scanned LSASS.exe (35.840 bytes / 36.864 on disk) from system32 dir (rmb process -> open file location) on and it's clean.. – user144773 Apr 22 '13 at 17:32
