Mine wouldn't be your best choice. I use BeyondTV with a Firefly remote which is really good, but designed for more specific use, although it works perfectly with Hulu desktoop also. Also, I'm using XP. There are a lot of MCE remotes available and some have options for mouse control. I'd make sure I read the reviews on them, though since I have heard complaints on some of the ones with extra features not working as they should with some basics. I picked up an MCE remote which is supposed to work with 7 and I tried it with XP and it works fine and the mouse is easy to use, but I don't know how it will work with WMC7. I got it at Meritline.com, but will warn you that they literally ship some items on a slow boat from China, but I only paid $8 for it and was honestly surprised it worked as well as it did.
Just go to NewEgg or do a google search and I'm sure you'll find one that suits your needs. Make sure it's and MCE remote and certified for Win7. It should put your system to sleep and also wake it up which a lot of other remotes don't do.
