Greetings from Slovakia. Here is my knowledge of using Windows Vista Business SP2 64 bit (OEM licensed)> Server 2008 (via Vista_SHA2_WUC) on a 13 year old ntb Fujitsu Esprimo V6545 in 2021.
- Windows Defender manually updated via mpas-fe from Microsoft,
- monthly cumulative updates from the Microsoft Update Catalog manually (last July 2021),
- .Net Framework 4.7.2 last update January 2020. (I have successfully installed .Net Framework 4.8, but I do not recommend disabling multiple applications that worked normally in Vista)
- Browsers:
IE9 - last update January 2020
MyPal 64bit –v. 29.2.1
Serpent 64bit -52.9.0 of July 9, 2021
New Moon 64bit –v.28.10.4a.1 of 8 July 2021
Default: 360 Chrome Browser v. 13.0.2250.0 (Chrome ver. 86.0.4249.198) with Chrome Store add-ons.
Security and protection: on a monthly basis, I manually run the applications JRT, RKill, mbam, Kaspersky TDSSKiller, HitmanPro_x64, adwcleaner-7-2-7. The system is clean, without MW, AdWare, SpyWare.
The peculiarity is that Microsoft did not end the updates for Server 2008 even in 2021, for which thanks, because the Vista OS team is still alive, fast, 99% usable even at the beginning of the third decade of the second millennium ...
