Does anyone else suffer from this problem? explorer.exe on Windows 7 x64 is using a lot of RAM. Is there anyway to stop it from using 150MB ram?

Nope, mine is using 12MB as of right now. Try running a virus scan.

i think mine only uses 37mb as i have 8gb of ram and things get bigger the more ram you have for some reason. like with 1.5gb ram it will idle total ram at around 800mb, then with 4gb its around 1.3gb and with 8 its 2gbs

Mine's using 16 MB ...

It may go up and down depending on how many Explorer windows you have open, etc., but it shouldn't be that high, I assume. Get some antivirus software, if you haven't already! It's ridiculous not to have antivirus software in this day and age.

Mine is using 44MB currently (and 303MB virtual), but I only use it for Start menu and taskbar - I practically never use it for file management. Anyway, high memory usage could be caused by shell extensions, since those live in Explorer, and many of them are written really badly.

Try enabling "Launch folder windows in a separate process" in Folder options, then monitor the usage of both explorer.exe copies you get (the first one is taskbar/start menu, the second one is for browsing). You might also find out that browsing to certain folder increases memory dramatically, if that happens, try to find out which file triggers that (and what shell extension is responsible). If nothing else, closing all folder Windows should get rid of the second Explorer process, which will free your memory (but then again, I don't see 150MB memory usage as problematic, especially on an x64 system - RAM is there to be used).

Mine's using 14 Mb of ram running Windows 7 Home Premium. I don't know what you're doing to use that much ram...

Try killing all explorer.exe processes (there will be multiple ones if you have folders set to run in a diff process than the desktop). Then restart explorer.exe. Its probably just some memory leak, but if it keeps coming back it could be a virus

Not necessarily - it's quite likely that a legitimate shell extension is broken and leaks memory.

In any case, run a virus scan (I suggest MSE and/or MBAM), disable any shell extensions which you may have installed and come back to the thread.

That's a good idea. You can disable/enable shell extensions easily with this small utility (there are versions for 32-bit and 64-bit Windows): http://www.nirsoft.net/utils/shexview.html
