Today, I had to make a terrible choice. My SP3 froze and then would not fully boot, stopping at the login screen without actually showing the login fields. I called MS tech support. After rebooting over a dozen times--the SP3 would not enter any safe or restore modes--the tech told me the only way was to completely wipe my system and start again. I asked to be escalated and was told I had to wait several days before escalation--"in case a patch comes out." After I noted that I would not be able to install any patch, the useless "tech" gave me the old "I'll get my supervisor" trick. After an hour on hold I hung up. (Yes, I know I'm the stupid one.) Then I called the MS store line. The rep was very friendly, but an "intermittent phone problem" on their end made it impossible to carry on a conversation. Even with regular backups, it would still take several days to reload my Surface from a full wipe and recent data would be lost forever. I decided to cut open the back of my machine to recover the mSATA drive and my data. MS can go to #@%!. I will NEVER buy another computer from them--ever. It was a top-of-the-line SP3. I had to destroy a very expensive computer or lose data forever. My wife was in the middle of entering several hours worth of financial data...never even had the chance to back it up. We've lost a machine my wife loved, a lot of money, and a ton of time. Now I'm waiting for my mSATA to SATA adapter to arrive so I can see if we even have any data left. #@%$ Microsoft. Never again.
