I had a few issues while attempting to upgrade my laptop from Windows 8 to Windows 8.1.
- If your harddrive is encrypted with something like TrueCrypt, you'll have to decode it, apply the upgrade and then re-encode it.
- A batch file script I use to sync podcasts between my PC and mp3 player had once gone a little nuts and written some files to my system reserved partition. This meant that there wasn't enough free space in there for the 8.1 upgrade to do its thing. I had to use a GParted Live CD to work out what was wrong and clean up the podcast mess.
Once the install of the 8.1 upgrade was completed the first thing I attempted to do was connect to one of the servers I manage via remote desktop. I usually do this by selecting the appropriate entry from my start -> run history. Imagine my joy to find out that all the entries for all commands had been removed. Thanks MS.
