Windows 7: 3GB Switch Question

3GB Switch Question

We are deploying 32bit and 64bit Win7 PCs here. I accidentally ran: BCDEDIT.EXE /Set IncreaseUserVa 3072 on a 64bit PC.

So, did I just restrict this PC to only using 3GB? And if I did, is there anything I can do to reverse it?

Thanks for any help!

Thanks for your help TGSoldier. Your response got me on the right track. The entry that worked was:
bcedit.exe /deletevalue IncreaseUserVa
I had to remove the 3072, I guess the 3072 was confusing it.

Thanks again!
