Today after recurrence of losing all my favorites Microsoft IE (I suppose it has something to do with OneDrive/Synchronization options, though could be updates related) I went on updates spree instead of properly and systematically researching the problem (kind of most tempting way when dealing with technical issues).
After installing bunch of Windows Updates along with refresh of laptop hardware drivers and BIOS firmware I ended up with VMware throwing following error at me:
And this is for VM which is previously worked fine and having about 30 GB of free RAM. At www.petri.com you can find quite good discussion of possible reasons and ways of addressing this problem, and in my case it was because of KB2995388, so I fixed it by removing this optional update.
This problem can be solved modifying config.ini file located by default at C:ProgramDataVMwareVMware Workstation.\nhttp://www.coretechnologist.com/forum-2/business-computing/not-enough-physical-memory-is-available-error-vmware/
I don’t remember exactly, but it seems that I tried something similar at the time I had this issue and it didn’t help me, but I’m not 100% sure.
