Problems with Vista SP1 & Applications

Microsoft said that Vista SP1 would offer application compatibility and driver improvements, but what i've experienced is that Vista SP1 delivers more problems than it fixes. And I thought Vista was supposed to be such a good OS (back when I first bought it on January 31, 2007) Overall, Vista works well for me, but after I installed the RC1 version of SP1, DesktopX wouldn't load and windows said something like "dxwidget.exe has stopped working" after startup.

My windows Complete PC Backup & Restore (I own the Business edition) stopped working shortly after I installed SP1 as well. After 4 months, i've decided to revert back to SP0 of Vista, and then DesktopX started to work again. But unfortunately, my Sidebar doesn't work sometimes, and backup still encounters problems. After I start a backup, Windows says that the backup failed, about one second later.

I want to know what's causing my sidebar and backup programs to stop working. The sidebar loads intermittently, and Windows Backup STOPPED WORKING since January. I have yet to see what other problems I have with Vista. I'm gonna stick with Vista SP0. I just hope that Windows 7 will solve these problems.

If you have any problems with Vista SP1, or Vista in general, feel free to reply.
