I have an MSI WindPad 110W that I bought new (not used) with 4 GB of memory installed and about 256 MB reserved for video. I did a clean install of Windows 8 on it and have since been using it.
After going to sleep (either automatically or manually) and being woken up I notice the memory (shown in Task Manager) is usually upwards of 80 or 90 % used. Usually there is one Metro/Windows Store app running, the Reader app that comes preinstalled with Windows and sometimes Firefox. Looking in Task Manager I do not see anything taking up the several gigabytes of memory Windows claims is in use. Is there something I should look further at or into to see what the cause is?
Here is Task Manager showing the problem. Note that 92% is about 3 GB and the highest process use is 37 MB by Explorer.

Finally, someone suggested Performance Monitor. This is what it shows:
Again, if anyone can help me correct this problem, or even help me confirm it is an actual bug in some software or Windows itself so I can stop using it/file a bug report, I'll be happy.
