I meant to have a new release of zcash4win out a while ago, and was (and still am going to) change the name, but have been delayed by illness!
Version 1.0.11 is entering auto-deprecation some time tomorrow when the block height for it gets hit, and I released version 1.0.12 of zcash4win earlier today on https://zcash4win.com
Just go into Add/Remove Programs, uninstall zcash4win, then double click the msi file for 1.0.12 to install the new release
In addition to bumping the zcash version to 1.0.12, it also flips the block explorer it uses to be https://zcashnetwork.info which shows unconfirmed transactions
Also for command line only Windows users, the zipfile for stand alone command line zcash for windows version 1.0.12 is now at https://zcash.dl.mercerweiss.com/zcash-win-v1.0.12.zip
Cheers and sorry again for the delay!
