Virtual PC - Differencing disk bloat
Hi,
I've installed Windows XP mode on Win7 x64, loaded the VM, run all the Windows Updates on it, which bloated the vhd file to over 3GB. I then merged the Windows XP Mode and Windows XP Mode Base vhds to create a new parent disk.
I then created a new differencing disk based on the new parent vhd. At first the file was very small, which I expected. However I left it running overnight (did not do any updates, software installs, anything) and now the differencing disk is 1667 MB!
Is this normal? I want to set up a test/development environment. Am I better off using a dynamic disk rather than differencing ones?
Thanks for any help!
Jim
