Hey guys, I thought it would be nice to have one central thread for any tweaks, fixes, or improvements that yuo might have for this device. Post away!
Here are a couple that are are from the Reddit FAQ
https://www.reddit.com/r/gpdwin/comments/5c9duk/gpd_win_general_faq/BIOS Changes for Performance Chipset Tab -> North Bridge -> Memory Configuration -> DRAM Speed Grade -> Fast
This BIOS setting can be missing from the list on the 10/25/2016 BIOS Revision (and perhaps others) if you have hit F3 to reset the BIOS to optimized defaults and have not yet rebooted since doing so. It will re-appear in the settings list after saving settings and rebooting. No cause is known for this behavior and it does not appear to be 100% consistent.
Chipset Tab -> North Bridge -> Intel IGD Configuration -> GFX Boost -> Enabled (Thanks /u/mefaun!)
BIOS Changes for Troubleshooting/Thermal (If you bugcheck/hard shutdown, try these) Advanced Tab -> CPU Configuration -> CPU Thermal Configuration -> DTS -> Enabled
Chipset Tab -> North Bridge -> Intel IGD Configuration -> IGD Thermal -> Enabled
Removable Windows Components Media Features - If you're installing MPC or any alternate Media Player, you can remove this.
Microsoft Print to PDF - If you're not printing to PDF, you can remove this.
Print and Document Services - If you're not printing from your GPD WIN, you can remove this.
Remote Differential Compression API Support - It is highly unlikely you will ever have a need for this, it is only used by a few specific applications. It is generally safe to remove.
Work Folders Client - If you're not synchronizing folders, you can remove this.
XPS Services -If you're not opening/using .XPS documents (you probably aren't), you can remove this.
XPS Viewer - If you're not opening/using .XPS documents (you probably aren't), you can remove this.
Windows Cleanup Commands Run Disk Cleanup against your C:\, clicking the button to "Clean Up System Files". This should reclaim ~4GB from a default install, more if you've installed updates or experienced a BSOD.
Run the following commands to clean your base image, reduce the size of your WinSxS folder, and reclaim other used space:
dism /online /Cleanup-Image /StartComponentCleanup /ResetBase
powercfg /h off
NOTE: The powercfg command listed above disables Hibernation support. If you intend to use Hibernation, you can safely skip that step.
Using the above, I was able to get the default install (not clean install) down to approximately 16.0GB used, after the W10 Anniversary edition installation.
You probably should do a clean install if you don't mind the hassle of doing so. You'll save more space, and based on anecdotal evidence you should have fewer issues overall.
