When I had 1,9001,900 items of various files & folders on my Desktop(Windows 7), explorer.exe/the Desktop was constantly crashing, and would take several seconds to load an explorer window[Windows key + E](if it happened at all).
After removing about 100 items, the problem went away. So, there seems to be a limit that Windows 7 can handle.
Also, having any shortcuts that no longer work willwill cause the Desktop to lag/crash.
