Probably.
in Essence, it was Windows XP's features with Windows 98SE's kernel, and an FAT32 file system instead of NTFS.
It was horribly unstable. So bad, in fact, that a friend told me that a shop refused to work on her laptop because it had Windows ME on it. I thought 98SE was a much better product. Its registry was a mess if memory serves me correctly.
The only real difficulty i had with Windows ME was when i got one of the first computer virii that existed, an old boot sector exploit. My own fault using old floppies that hadn't been virus checked. All that was required was the insertion of the DOS Disk, and an fdisk /mbr command.
As i said in my post, the key to Windows ME was to keep the registry clean. For that purpose i use System Mechanic's registry cleaning tool once a week. The laptop still runs fine with Windows ME.
Fact is that all operating systems will have individual quirks. This includes the various flavours of Windows. For example: i run SuSE 9.2 Professional on this machine with a dialup connection. Last week as i was getting SuSE updates from one of their ftp sites, my connection died. i couldn't get back on line. It seems that my modem commands were changed. i didn't know the Hays modem commands, so i was pretty screwed. Couldn't have the modem redetected and configured for some reason. Ended up that i had to insert a Knoppix CD, run kppp and look at the modem command set after i configured the Internet tool. Copied that into SuSE's kppp utility, and was back in business. The quirk involved is that SuSE (and Redhat/Fedora) both have messed up their internet connection tools. i still can't connect with kinternet.
