How To Fix Windows 8.1 Upgrade Error Code 0x800706BE

Reader Question:
“Hi Wally, When I try to upgrade my Lenovo laptop it gives me error code 0x800706BE and the upgrade fails. I’m trying to install Windows 8.1.“ - Evan L., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.
