Run separate explorer window as Admin

This can be accomplished in 2 ways:

1. best, most reliable method, uses undocumented /separate switch, launches explorer in a separate process

runas /u:domain\username "explorer.exe /separate"

2. Per-user setting, but can be set in default user profile so that it works for all users

in an explorer window: Folder Options>View tab>Advanced Settings>Launch folder windows in a separate process.
If this setting is enabled, then the command below will work (without the /separate switch)

runas /u:domain\username explorer.exe

more far-reaching fix if you have a 'Pro' version of windows 7 - editing local group policy:
start>Run>gpedit.msc
Computer Configuration>Administrative Templates>System>Power Management>Sleep Settings>

Set
Allow Applications to Prevent Automatic Sleep (On Battery)
and
Allow Applications to Prevent Automatic Sleep (Plugged In)

to disabled.

but this applies to ALL applications, not just chrome.
