I always assumed it was just used so that it didn't scare end users into thinking their PC was about to crash.

From my own test I find out that turning screen updating off and on takes about 15ms (tested in C# via Excel Interop).
Both affected computers (if it IS the computers which affected) are 8-year-old laptops and no changes to BIOS have been made to them. I find this information through RUN, msinfo32, - BIOS version/date: TOSHIBA v2.30 , 3/18/2008 SMBIOS version: 2.4 BOOT DEVICE: \Device\Harddisk Volume2 Operating System version: 6.0.6002 Service Pack 2 Build 6002 - That is for MY computer; not the other person's. Other than the difficulties currently with Windows Update, everything seems to operate normally. In Services is Bits (Background Intelligent Transfer Service) started?
Something is going on with Microsoft's Update Servers.
Screen Updating = False 'swap between sheets 1/2 (need both sheets or this will crash) For i = 1 To numb Switches Sheets(1 (i Mod 2)). Screen Updating = True 'get results for part two results = results & vb Cr Lf & "Screen Updating IS disabled: " & Format(Time - start Time, "hh:mm:ss") & " seconds" 'show results Msg Box results End Sub Firstly I've been using the script written by Richie (UK) Post #7 Here It simply iterates through a loop changing the value of i in one cell.
I have changed it slightly so it loops 10,000 times and I execute it 10 times for sample size.
Keep that on mind if you will execute anything which would take less time.
And after all don’t turn screen updating on/off many times in some loop. And one more note (which you probably don’t want to hear) if you want it quick use C .
Other kinds of software updates are working well on both machines.
