dwm.exe causing problems?

“Desktop Window Manager has stopped working and will be closed.”

Get that much? Usually it is because of a graphics card driver meltdown. In cases like mine at work, I like to disable DWM when possible. Users do not “need” the fancy aero interface. I want their machines to run faster and happier without the DWM hog.

Hit the magic windows button (start)

In the start search window type in Services and hit enter

When the services window comes up, scrolll down or type des to have it automagically take you to:

Desktop Window Manager Session Manager

Double click that

In the dropdown for startup type, change it to disabled.

Hit apply then ok.

Reboot. look at your ram and proc utilization now. Happy huh?

IF you couldn’t run services.msc, you may need permission from a network admin. Or you can right click on it and hit run as administrator if you are the admin. πŸ™‚

Once again… you don’t know what you’re talking about here… If you really do not want the aero interface ‘fine’… but *DO NOT* disable DWM to achieve that! Just select the classic theme and leave it at that.

If you actually understood what DWM does, then you would understand why you do not disable it!!!

start> type incom hit enter net stop “Desktop Window Manager” that is faster for me. I like not having the service run. My school says don’t run services you don’t need for your business. Please let me know if my business is losing money because DWM is off. I’ll buy you a soda or if we are losing a lot of money by turning off DWM, I’ll buy you something nicer. I think my company was losing money with it on because I have some spiceworks tickets to show for it that cost money to resolve and (only) 1 support session with a vendor telling me to disable the service. Anyhow turning it off eliminates nonsense like DWM_SOURCE_FRAME_SAMPLING, DWMFLIP3DWINDOWPOLICY that aren’t needed when classic theme is applied. Sure they don’t get used as much (on classic) but you can see it with a big long trace of all file access on your machine. Try it, its fun. You like classic? cool. Go for it. Nobody said you had to agree with my way, I’m just offering help for somebody that might not know “a” way. Now they know 2 thanks to you if they stumbled on my lame site. I do appreciate you taking the time to add to it. And call me stupid. πŸ™‚ Makes me chuckle.
